Technical Field

The present invention relates to a straddle-type vehicle, and more particularly to a structure of a tail lamp unit and a rear body cover of the straddle-type vehicle.

Background

Previously, there has been a saddle-riding type vehicle having an integrated tail lamp unit disposed to protrude from a rear body cover.

For example, in a saddle riding type vehicle disclosed in patent document 1, an integrated tail lamp unit is disposed in a rear body cover provided at a rear portion of a vehicle body, and a portion of a translucent cover thereof protrudes from the rear body cover. The integrated tail lamp unit is formed by integrating the tail lamp part and the stop lamp part and is covered by one translucent cover. The tail lamp unit and the stop lamp unit are the same lamp, and are turned on as the tail lamp during normal running and as the stop lamp during operation of the brake, and the brightness is brighter.

In addition, the left winker unit and the right winker unit in patent document 1 are disposed on both sides of the tail lamp unit in the rear view of the vehicle.

Patent document 1: JP 2005-119570A

Disclosure of Invention

[ problems to be solved by the invention ]

However, in the vehicle of patent document 1, since the translucent cover that allows light of the tail lamp unit to pass therethrough protrudes from the rear body cover and part of the light is refracted, reflected, or scattered in the translucent cover, even if a reflecting member that guides the light to the rear of the vehicle is provided around the lamp, scattering of the light to the outer periphery of the tail lamp unit cannot be suppressed. The actual light emission range of the tail lamp unit in the rear view of the vehicle is larger than the area of the translucent cover in the rear view of the vehicle. Further, since the brightness of the stop lamp portion corresponds to the maximum brightness of the tail lamp unit, the extension of the light emission range is more remarkable when the brake is operated.

In patent document 1, there is no structure for separating the tail lamp unit and the turn signal lamp units disposed on the left and right sides, respectively, and the brightness when the turn signal lamp units are turned on is almost the same as the brightness when the stop lamp units are turned on, so that there is a possibility that the tail lamp units and the turn signal lamp units interfere with each other due to the spread of the light emission ranges of the turn signal lamp units.

For example, when the brake lamp portion is turned on by operating the brake while the turn lamp portion is turned on, strong light from the brake lamp portion is scattered to a light emission range of the turn lamp portion when the vehicle is viewed from behind, and interference with the turn lamp portion occurs. Alternatively, when the winker lamp unit is turned on to notify the driver of the turning direction of the vehicle behind while the stop lamp unit is turned on, strong light from the winker lamp unit is scattered in the light emission range of the tail lamp unit when the vehicle is viewed behind, and thus interference with the stop lamp unit occurs.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a saddle-ride type vehicle having high visibility between light emission ranges of a stop lamp unit and a turn lamp unit even when the stop lamp unit and the turn lamp unit are simultaneously turned on.

[ means for solving problems ]

In order to improve the visibility of the light emission range of the brake lamp unit in the rear view of the vehicle, the inventors of the present invention first conceived to house the tail lamp unit inside the rear body cover so that the translucent cover of the integrated tail lamp unit does not protrude from the rear body cover.

Therefore, when the turn lamp part and the brake lamp part are simultaneously lighted, the mutual interference can be avoided. However, since other parts such as a storage box and a seat lock device are also disposed in the rear vehicle body cover, the space is limited. If the tail lamp unit is completely accommodated in the rear body cover, the rear body cover may become large, the external shape of the vehicle may also become large, and the maneuverability of the vehicle may be deteriorated.

In addition, the size of the vehicle in the vertical direction is not suitable to be increased in consideration of the comfort of the driver in placing his feet. The tail lamp and the turn lamp cannot be further apart in the up-down direction. Further, there is also a method of increasing the distance between the tail lamp unit and the turn lamp unit in the lateral direction, but this increases the lateral dimension of the vehicle, and deteriorates the vehicle mobility.

Under such circumstances, the present inventors paid attention to the fact that the intensity of the light of the tail lamp unit is considerably weaker than that of the stop lamp unit, and studied the internal structure of the tail lamp unit to improve the visibility of the stop lamp unit.

First, the present inventors changed the integrated tail lamp unit to be divided into the lighting areas of the tail lamp section and the stop lamp section, and disposed the stop lamp section at the center in the left-right direction, and disposed the stop lamp section and the turn lamp section as far apart as possible, so as to reduce the degree of mutual interference.

Further, a diffusion member is added to the tail lamp section, and the diffusion member is disposed to separate the stop lamp section from the turn lamp section in the rear view of the vehicle. The diffusion member not only makes the lamp shape inside not appear and makes the luminance uniform, but also has the effect of reducing the light transmittance. Therefore, after the diffusion member is added to the tail lamp section, the tail lamp section becomes darker and the brightness is kept uniform.

By arranging the diffusion member that can make the outer peripheral portion of the tail lamp unit darker and maintain uniform brightness, the light emission range of the tail lamp unit can be more concentrated than in the previous integrated tail lamp unit. Therefore, even if the brightness of the brake lamp portion when turned on is the same as the brightness of the turn lamp portion when turned on, the tail lamp portion having relatively dark brightness and relatively concentrated light emission ranges is interposed between the brake lamp portion and the turn lamp portion, so that the visibility of the light emission ranges when the brake lamp portion and the turn lamp portion are simultaneously turned on can be improved.

On the other hand, the tail lamp portion incorporating the diffusion member has a considerably lower luminance than the winker portion, and the recognition of the tail lamp portion may be degraded when the winker portion is lit. In view of the above, the present inventors have further examined the shape of the rear body cover and finally studied a novel method capable of solving the above-mentioned problems at the same time. The following explains the constitution of the invention obtained by the inventors after various investigations and developments.

A saddle-riding vehicle according to embodiment 1 of the present invention is characterized by comprising: a rear body cover disposed at a rear portion of a vehicle body, a tail lamp unit disposed at the rear body cover, a left turn lamp unit disposed at the rear body cover and located more leftward than the tail lamp unit, and a right turn lamp unit disposed at the rear body cover and located more rightward than the tail lamp unit; the tail light unit includes: a stop lamp section disposed at the center in the left-right direction and turned on in association with a brake operation, a tail lamp section that can be turned on during traveling, a base that holds the stop lamp section and the tail lamp section, and a translucent cover disposed behind the base and separate from the base; the light-transmitting cover is provided with a light irradiation surface which enables the light emitted from the brake lamp part and the tail lamp part to penetrate towards the outside of the vehicle body; the tail lamp part is provided with a left diffusion part which is at least arranged between the brake lamp part and the left turn lamp part under the rear view of the vehicle, and a right diffusion part which is at least arranged between the brake lamp part and the right turn lamp part; a tail lamp unit accommodating portion for accommodating at least a part of the tail lamp unit is provided in the rear body shell; the tail lamp unit housing portion has a peripheral wall portion that protrudes rearward with respect to a surface of the rear body cover and is formed continuously at least on a left side, an upper side, and a right side of the tail lamp unit; the peripheral wall portion is disposed at least at a position separating the left diffusion member and the left turn signal lamp portion and at a position separating the right diffusion member and the right turn signal lamp portion, protrudes rearward from rear ends of the left turn signal lamp portion and the right turn signal lamp portion in a vehicle side view, and shields the light irradiation surface in the vehicle side view.

According to embodiment 1 of the present invention, the stop lamp portion is disposed at the center in the left-right direction, and the stop lamp portion and the turn lamp portion are disposed as far apart as possible while suppressing an increase in size of the rear portion of the vehicle, thereby greatly reducing the degree of mutual interference at the time of lighting.

The tail lamp unit has a left diffusion member disposed at least between the stop lamp unit and the left turn lamp unit and a right diffusion member disposed at least between the stop lamp unit and the right turn lamp unit in a rear view of the vehicle. Thus, even if the brightness of the brake lamp portion when lit is substantially the same as the brightness of the turn lamp portion when lit, the tail lamp portion having relatively dark brightness and clearly concentrated light emission ranges is interposed between the brake lamp portion and the turn lamp portion, so that the visibility of the light emission ranges when the brake lamp portion and the turn lamp portion are lit simultaneously can be improved.

The tail lamp unit housing portion has a peripheral wall portion that protrudes rearward from the surface of the rear vehicle body housing and is formed continuously at least on the left, upper, and right sides of the tail lamp unit, and the peripheral wall portion is disposed at least at a position that separates the left diffusion member and the left winker portion and at a position that separates the right diffusion member and the right winker portion, protrudes rearward from the rear ends of the left winker portion and the right winker portion in a vehicle side view, and shields a light irradiation surface in the vehicle side view. Even if the turn signal lamp portions on the left and right sides are turned on or stray light such as a street light is emitted from above the straddle-type vehicle, the light hardly enters the tail lamp unit housing portion, and therefore a "dark area" is formed in the tail lamp unit housing portion. Since the diffusion member of the tail lamp unit is located in the "dark area", the tail lamp unit can be easily viewed even when the brightness of the tail lamp unit is low.

In particular, the peripheral wall portion shields not only the diffusion member of the tail lamp portion but also the light irradiation surface of the light-transmitting cover through which light from the tail lamp unit passes in a vehicle side view, and therefore light refracted, reflected, or scattered at the light-transmitting cover cannot be scattered toward the outer periphery of the tail lamp unit. Thus, the light emission range of the tail lamp unit in the vehicle rear view substantially matches the area of the translucent cover in the vehicle rear view, and the light interference from the winker unit is not received, so that the visibility of the light emission range of the tail lamp unit can be improved.

Therefore, according to embodiment 1 of the present invention, it is possible to provide a straddle-type vehicle in which the visibility of the light emission ranges of the stop lamp portion and the turn lamp portion is improved and the visibility of the light emission range of the tail lamp portion is improved, respectively, while suppressing the increase in size of the rear portion of the vehicle.

In embodiment 2 of the present invention, the stop lamp unit includes a stop lamp light source that emits light in the direction of irradiation of the tail lamp unit; the tail lamp unit has a tail lamp light source that emits light in the same direction as the stop lamp light source.

According to the 2 nd aspect of the present invention, the tail light source of the tail light section is directed in the same irradiation direction as the stop light source of the stop light section. Thus, the tail lamp unit does not need to reserve a space for reflecting light, and the dimensions of the tail lamp unit and the tail lamp unit housing portion in the front-rear direction can be shortened. Therefore, the dimension of the vehicle in the front-rear direction can be shortened, and the mobility of the vehicle can be improved.

In the saddle-riding vehicle according to claim 3 of the present invention, the stop lamp portion has an extension portion that surrounds the stop lamp light source and extends rearward; the left diffusion member and the right diffusion member are disposed at the same position as the rear edge of the extension portion in the front-rear direction.

According to the 3 rd aspect of the present invention, the stop lamp light source is disposed further forward than the diffusion member of the tail lamp unit, that is, at a relatively rear position in the tail lamp unit. Therefore, the light of the stop lamp part is limited by the extension part and is not scattered towards the peripheral direction, so that the boundary of the light is more clear. In other words, the diffusion member of the tail lamp portion is less likely to be interfered by light of the stop lamp portion when the stop lamp portion is lit, and the light emission range of the stop lamp portion can be clearly distinguished from the light emission range of the tail lamp portion when viewed from the rear of the vehicle. Therefore, the visibility of the light emission range of the tail lamp unit can be further improved.

In the saddle-riding vehicle according to claim 4 of the present invention, the light-transmitting cover has a stop lamp facing portion facing the stop lamp light source, and a tail lamp facing portion facing the left and right diffusion members; the tail lamp facing portion is disposed rearward of the stop lamp facing portion.

According to the 4 th aspect of the present invention, since the tail light opposing portion is disposed further rearward than the stop light opposing portion, when light from the stop light source passes through the stop light opposing portion of the light-transmitting cover, light refracted, reflected, or scattered at the stop light opposing portion is separated from light refracted, reflected, or scattered at the tail light opposing portion in the front-rear direction. In other words, a region where light is hardly emitted is interposed between the stop lamp facing portion and the tail lamp facing portion in the front-rear direction of the light emitting region.

Thus, the non-light-emitting region can separate the light-emitting region of the stop lamp facing portion from the light-emitting region of the tail lamp facing portion when viewed from diagonally behind the vehicle, so that the stop lamp facing portion can be more clearly distinguished from the tail lamp facing portion. Therefore, the visibility of the light emission range of the tail lamp unit can be further improved.

In the saddle-riding vehicle according to the 5 th aspect of the present invention, the left turn lamp portion has a left turn lamp translucent cover through which light from the light source of the left turn lamp portion passes, and the right turn lamp portion has a right turn lamp translucent cover through which light from the light source of the right turn lamp portion passes; and under the rear view of the vehicle, the area of the opposite part of the brake lamp is smaller than the area of each of the left steering lamp light-transmitting cover and the right steering lamp light-transmitting cover.

According to the 5 th aspect of the present invention, the area of the stop lamp opposing portion is smaller than the area of each of the left and right turn lamp translucent covers in the vehicle rear view, and the degree of interference between the portions can be reduced. Therefore, the visibility between the light emission range of the stop lamp portion and the light emission range of the turn lamp portion can be further improved while suppressing an increase in size of the rear portion of the vehicle.

In the saddle-riding vehicle according to the 6 th aspect of the present invention, the translucent cover has a translucent cover peripheral wall portion that extends forward from the outer periphery of the tail lamp opposing portion, and the tail lamp unit housing portion has a rear edge portion that extends inward from the peripheral wall portion toward the tail lamp unit housing portion and that shields the translucent cover peripheral wall portion from the rear view of the vehicle.

According to the 6 th aspect of the present invention, the tail lamp unit housing portion has a rear edge portion that extends from the peripheral wall portion toward the inside of the tail lamp unit housing portion and that shields the translucent cover peripheral wall portion from the rear view of the vehicle. Thus, even if the "dark area" formed by the peripheral wall portion of the tail lamp unit housing portion receives light from the vehicle obliquely rearward due to the irradiation of another vehicle, the rear edge portion can shield a part of the light, and the darkness of the "dark area" can be maintained more reliably. Therefore, the visibility of the light emission range of the tail lamp unit can be further improved.

In the saddle-riding vehicle according to embodiment 7 of the present invention, the tail lamp unit housing portion has a flange portion that extends from the rear edge portion toward an inside of the tail lamp unit housing portion and that shields a part of the tail lamp facing portion from a rear view of the vehicle.

According to the 7 th aspect of the present invention, the tail lamp unit housing portion has a flange portion that extends from the rear edge portion toward the inside of the tail lamp unit housing portion and that shields a part of the tail lamp facing portion from a rear view of the vehicle. Thus, even if the "dark area" formed by the peripheral wall portion of the tail lamp unit housing portion receives light from the vehicle obliquely rearward by irradiation of another vehicle, the flange portion can shield a part of the light, and the darkness of the "dark area" can be maintained more reliably. Therefore, the visibility of the light emission range of the tail lamp unit can be further improved.

In the saddle-riding vehicle according to embodiment 8 of the present invention, the tail lamp facing portion, the left diffusion member, and the right diffusion member are arranged so as to be located more rearward as they go to the outer periphery.

According to the 8 th aspect of the present invention, since the tail lamp opposing portion, the left diffusion member, and the right diffusion member are disposed so as to be located more rearward as they go to the outer periphery, the stop lamp opposing portion and the stop lamp light source can be easily visually recognized from diagonally rearward of the vehicle even if the light emitting area of the stop lamp portion is small. Therefore, the visibility of the light emission range of the stop lamp portion can be further ensured.

In the saddle-riding vehicle according to claim 9 of the present invention, the tail lamp unit has a circular shape in a rear view of the vehicle.

According to the 9 th aspect of the present invention, since the shape of the tail lamp unit is circular, the area is smaller than that of a quadrangle having the same vertical dimension and the same horizontal dimension, but the visibility in the rear view of the vehicle is substantially the same, and therefore the number of lamps can be reduced, and the rear body cover can be further miniaturized.

In the saddle-riding vehicle according to the 10 th aspect of the present invention, the left diffusion member and the right diffusion member are formed in an annular shape so as to surround the stop lamp light source in a rear view of the vehicle.

According to the 10 th aspect of the present invention, the left and right diffusing members are formed in an annular shape so as to surround the stop lamp light source in a rear view of the vehicle. Thus, the stoplight light source can be completely surrounded by the diffusion member which makes the boundary of light most clear, and therefore, the visibility of the stoplight portion in the rear view of the vehicle can be further improved.

In fig. 5(a) to 5(c), the light-transmitting cover 34 is omitted in order to make the stop lamp section 31 and the tail lamp section 32 clearly visible, and the left diffusion member 32bl, the right diffusion member 32br, and the diffusion member 32b are shown by two-dot chain lines. Other components such as the rear body cover RC are also omitted.

As shown in fig. 4 and 5, the tail lamp unit 3 is disposed at the center in the left-right direction when mounted on the vehicle, and includes a stop lamp unit 31 that is lit in association with a braking operation, a tail lamp unit 32 that is disposed on the outer periphery of the stop lamp unit 31 and is lit during traveling, a base 33 that holds and accommodates the stop lamp unit 31 and the tail lamp unit 32, and a translucent cover 34 that is disposed behind the base 33 and is separate from the base 33.

In the embodiment of fig. 4, the LEDs as the stop lamp light sources 31a of the stop lamp unit 31 and the LEDs as the tail lamp light sources 32a of the tail lamp unit 32 are disposed on the same substrate 39. A substantially circular partition wall 39a is formed on the outer periphery of the stop lamp light sources 31a, and the arrangement region of the tail lamp light sources 32a and the arrangement region of the stop lamp light sources 31a are distinguished by this partition wall 39 a.

3.1 brake light part 31

Fig. 6(a) is a cross-sectional view taken along line B-B of fig. 5(C), and fig. 6(B) is a cross-sectional view taken along line C-C of fig. 5 (C). As shown in fig. 6(a) and 6(b), the stop lamp portion 31 disposed at the lateral center of the tail lamp unit 3 includes a stop lamp light source 31a and an extension portion 31b that surrounds the stop lamp light source 31a and extends rearward.

The extension 31b is made of a material that is opaque and reflective to light, and can block the scattering of the light from the stop lamp light source 31a to the surroundings. The rear edge of the extension 31b is disposed at substantially the same position as a diffusion member 32b of a tail lamp unit 32 described later in the front-rear direction. In other words, the stop lamp light source 31a is disposed further forward than the diffusion member 32b, that is, at a position relatively rearward of the tail lamp unit 3.

3.2 taillight section 32

As shown in fig. 4, 6 a, and 6 b, the tail lamp unit 32 includes a tail lamp light source 32a, a diffusion member 32b (a dotted hatching in fig. 3 and 4) located behind the tail lamp light source 32a, and a support wall 32 c.

As shown in fig. 5(a) to 5(c), the diffusion member 32b may be divided into a left diffusion member 32bl positioned on the left side of the center in the left-right direction of the tail light unit and a right diffusion member 32br positioned on the right side of the center in the left-right direction of the tail light unit. The left diffusing member 32bl and the right diffusing member 32br may be formed integrally or may be formed separately. When the left diffusion member 32bl and the right diffusion member 32br are formed as separate and distinct bodies, the tail light source 32a of the tail light unit 32 is preferably configured to be separated to the left and right correspondingly. In this case, the tail lamp unit 32 may be separated to the left and right.

The left diffusion member 32bl is disposed at least between the brake lamp unit 31 and the left turn lamp unit 4 in the vehicle rear view. The right diffusion member 32br is also disposed at least between the stop lamp portion 31 and the right turn lamp portion 5 in the rear view of the vehicle.

Specifically, as shown in fig. 5(a), the left diffusion member 32bl has at least a portion overlapping with a virtual connection line connecting the center point 31c of the stop lamp portion 31 and the center point 4c of the left turn lamp portion 4 in the vehicle rear view. The right diffusion member 32br has at least a portion overlapping with a virtual connection line connecting the center point 31c of the stop lamp portion 31 and the center point 5c of the right turn lamp portion 5 in the vehicle rear view.

As shown in fig. 5(b), the left diffusion member 32bl preferably has a portion overlapping a range between a line connecting the upper end point 31u of the stop lamp portion 31 and the upper end point 4u of the left turn lamp portion 4 and a line connecting the lower end point 31d of the stop lamp portion 31 and the lower end point 4d of the left turn lamp portion 4. Further, the right diffusion member 32br has a portion overlapping with a range between a line connecting the upper end point 31u of the stop lamp portion 31 and the upper end point 5u of the right turn lamp portion 5 and a line connecting the lower end point 31d of the stop lamp portion 31 and the lower end point 5d of the right turn lamp portion 5.

Preferably, as shown in fig. 5(c), the left diffusion member 32bl and the right diffusion member 32br are disposed along the outer periphery of the brake light portion 31 so as to completely surround the brake light portion 31 in the rear view of the vehicle.

As shown in fig. 4, 6(a), and 6(b), the diffusion member 32b includes an inner peripheral flange portion 32bn provided on the inner periphery and extending forward, an outer peripheral flange portion 32bg provided on the outer periphery and extending forward, and a light source facing surface 32bm provided between the inner peripheral flange portion 32bn and the outer peripheral flange portion 32bg and facing the tail light source 32 a. Further, the outer peripheral flange portion 32bg of the diffusion member 32b is engaged with the rear end of the support wall 32 c.

3.3 light-transmitting cover 34

The light-transmitting cover 34 includes a stop lamp facing portion 37 facing the stop lamp light source 31a, a tail lamp facing portion 38 facing the diffusion member 32b (portions indicated by hatching located on the outer periphery of the stop lamp facing portion 37 in fig. 6 a and 6 b), and a light-transmitting cover peripheral wall portion 36 located on the outer periphery of the tail lamp facing portion 38 and extending forward and substantially parallel to the irradiation direction of the tail lamp unit 3. The light-transmitting cover 34 defines a portion through which light emitted from the stop lamp 31 and the tail lamp 32 is transmitted and emitted toward the outside of the vehicle body as a light irradiation surface 35.

In the embodiment shown in fig. 6(a) and 6(b), the light irradiation surface 35 of the light-transmitting cover 34 corresponds to a range including the stop lamp facing portion 37 and the tail lamp facing portion 38.

As shown in fig. 6 b, the tail lamp facing portion 38 (a portion indicated by diagonal hatching located on the outer periphery of the stop lamp facing portion 37) of the present invention is disposed rearward of the stop lamp facing portion 37 in the vehicle plan view. That is, the tail lamp facing portion 38 and the stop lamp facing portion 37 are arranged to be shifted in the front-rear direction. Therefore, the light irradiation surface 35 corresponding to the range including the stop lamp facing portion 37 and the tail lamp facing portion 38 has a shape recessed forward.

Specifically, an inner peripheral flange portion 38n extending forward is provided on the inner periphery of the tail lamp facing portion 38. The tail lamp facing portion 38 is connected to the stop lamp facing portion 37 by an inner peripheral edge portion 38n located on the inner periphery. As shown in fig. 6(a) and 6(b), the inner peripheral flange portion 38n is formed so as to be closer to the center of the light irradiation surface 35 as it goes forward. That is, the diameter of the inner peripheral flange portion 38n is formed to decrease toward the front.

The outer periphery of the tail lamp facing portion 38 is provided with an outer peripheral flange portion 38g extending forward. The tail lamp facing portion 38 is connected to the light-transmitting cover peripheral wall portion 36 by an outer peripheral flange portion 38g located on the outer periphery. Further, a fitting recess k2 described later is formed at the connecting position between the outer peripheral flange portion 38g and the light-transmitting cover peripheral wall portion 36.

The inner peripheral flange portion 38n and the outer peripheral flange portion 38g of the tail lamp facing portion 38 are substantially parallel to the light emitted from the diffusion member 32b, and therefore, substantially no light is emitted. The portion of the tail lamp opposing portion 38 between the inner peripheral flange portion 38n and the outer peripheral flange portion 38g is a light emitting region in the tail lamp opposing portion 38 because it is substantially perpendicular to the light emitted from the diffusion member 32 b. In contrast, the stop lamp facing portions 37 are all light-emitting regions since they are substantially perpendicular to the light emitted from the stop lamp light source 31 a.

The stop lamp facing portion 37 is disposed at substantially the same position as the light source facing surface 32bm of the diffusion member 32b in the front-rear direction. The stop lamp facing portion 37 is disposed further forward than the rear end of the inner peripheral flange portion 38n of the tail lamp facing portion 38, and the stop lamp facing portion 37 is also disposed further forward than the rear end of the outer peripheral flange portion 38g of the tail lamp facing portion 38.

In addition, the surface of the stop lamp facing portion 37 is formed to be convex toward the rear. In other words, the stop lamp facing portion 37 is formed so that the center is located more rearward than the outer periphery.

3.4 other features of the taillight Unit 3

As shown in fig. 6(a), the substrate 39 supporting the stop lamp light sources 31a and the tail lamp light sources 32a is configured such that the substrate surface is inclined slightly upward from the irradiation direction of the stop lamp light sources 31a and the tail lamp light sources 32 a. In the present embodiment, the inclination is made to be approximately 8.2 degrees upward. Therefore, the lower diffusion member 32b is located further rearward than the upper diffusion member 32 b. The lower tail lamp opposing portion 38 (a portion indicated by hatching located on the outer periphery of the stop lamp opposing portion 37) is also located further rearward than the upper tail lamp opposing portion 38. The tail lamp facing portion 38 located lower than the stop lamp facing portion 37 is arranged further rearward than the tail lamp facing portion 38 located higher than the stop lamp facing portion 37. Accordingly, when the stop lamp facing portion 37 and the stop lamp light source 31a are viewed from obliquely above the vehicle, the portion shielded by the tail lamp facing portion 38 can be reduced, so that even if the light emitting area of the stop lamp portion is small, the stop lamp portion can be easily viewed from obliquely behind the vehicle, and the visibility of the stop lamp portion can be ensured.

As shown in fig. 6(a) and 6(b), both the stop lamp light source 31a and the tail lamp light source 32a are provided on the substrate 39 so as to be directed toward the irradiation direction of the tail lamp unit 3. That is, the tail light source 32a and the stop light source 31a are directed in the same irradiation direction. Therefore, the lights emitted from the stop lamp light sources 31a and the tail lamp light sources 32a can be emitted toward the outside of the vehicle body without using a reflecting device. Specifically, the light emitted from the stop lamp light source 31a and the tail lamp light source 32a is emitted rearward in the front-rear direction of the vehicle. The tail light source 32a is provided with 12 LEDs annularly around the stop light source 31 a.

As shown in fig. 4, 6(a), and 6(b), the tail lamp facing portion 38 and the diffusion member 32b are both provided so as to be located more rearward as they go to the outer periphery. Specifically, the tail lamp facing portion 38 is provided such that the rear end of the outer peripheral flange portion 38g is located more rearward than the rear end of the inner peripheral flange portion 38 n. The diffusion member 32b is also provided so that the rear end of the outer peripheral flange portion 32bg is located rearward of the rear end of the inner peripheral flange portion 32 bn. The tail lamp facing portion 38 is provided such that the length of the outer peripheral flange portion 38g in the front-rear direction is greater than the length of the inner peripheral flange portion 38n in the front-rear direction.

As shown in fig. 3, 7, and 8, the area of the stop lamp opposing portion 37 is smaller than the area of each of the left and right blinker translucent covers 41 and 51 in the rear view of the vehicle. Specifically, the length of the stop lamp opposing portion 37 in the left-right direction is smaller than the length of each of the left and right blinker translucent covers 41 and 51. The length of the stop lamp opposing portion 37 in the vertical direction is smaller than the length of each of the left and right blinker translucent covers 41 and 51.

Fig. 3 and 4 show examples in which the outer peripheral contour of the light irradiation surface 35 of the tail light unit 3 may be substantially circular in the rear view of the vehicle. Specifically, in the embodiment shown in fig. 3, 4, and 5(c), the shape of the stop lamp facing portion 37 is substantially circular in the vehicle rear view, and the tail lamp facing portion 38 is formed in a ring shape along the outer periphery of the stop lamp facing portion 37 so as to surround the stop lamp facing portion 37. Therefore, the overall shape of the stop lamp facing portion 37 and the tail lamp facing portion 38 is substantially circular.

In the embodiment shown in fig. 3, 4, and 5(c), the entire diffusion member 32b including the left diffusion member 32bl and the right diffusion member 32br is disposed along the outer periphery of the brake lamp facing portion 37 in the rear view of the vehicle. That is, the diffusion member 32b is formed in an annular shape as a whole in the vehicle rear view, and surrounds the brake lamp facing portion 37.

4. Positional relationship between tail lamp unit 3 and left and right winker units 4 and 5

Fig. 7 is a sectional view taken along line a-a of fig. 3. As shown in fig. 7, the left winker part 4 includes a left winker translucent cover 41 and a left winker light source 42 located in front of the left winker translucent cover 41. The left winker translucent cover 41 allows light from the left winker light source 42 to pass through. The right turn light part 5 has a right turn light translucent cover 51 and a right turn light source 52 located forward of the right turn light translucent cover 51. The right turn light transmissive cover 51 allows light from the right turn light source 52 to pass through. A preferred configuration is such that both the left and right blinker light sources 42, 52 are located further forward than the base 33 of the tail light unit 3. A preferred arrangement is that both the left and right turn light transparent covers 41 and 51 are positioned forward of the light irradiation surface 35 of the transparent cover 34. Preferably, the left and right winker translucent covers 41 and 51 are both positioned forward of the diffuser member 32 b. A preferred arrangement is that both the left and right winker translucent covers 41, 51 are positioned forward of the stop and tail light sources 31a, 32 a.

Thus, the tail lamp unit 3 is less likely to be interfered by light from the left and right winker lamp units 4 and 5, and thus the visibility of the tail lamp unit and the stop lamp unit can be further improved.

Fig. 8 is an enlarged left side view of the rear part of the saddle-riding type vehicle 1 of the present invention, showing the positional relationship between the members located inside the tail lamp unit 3 and the left and right winker parts 4, 5. The portion surrounded by the two-dot chain line has a cross-sectional structure of the tail light unit 3 and the tail light unit accommodating portion 25 along the line B-B in fig. 5 (c). As shown in fig. 8, the tail lamp unit 3 is preferably disposed at a position rearward of the left winker unit 4 and the right winker unit 5. More specifically, it is preferable that the stop lamp light source 31a and the tail lamp light source 32a of the tail lamp unit 3 are located behind the left winker unit 4 and the right winker unit 5, the stop lamp facing portion 37 is located behind the left winker unit 4 and the right winker unit 5, the tail lamp facing portion 38 is located behind the left winker unit 4 and the right winker unit 5, and the diffusion member 32b is located behind the left winker unit 4 and the right winker unit 5. Thus, the tail lamp unit 3 is less likely to be interfered by the light from the winker lamp units 4 and 5, and hence the visibility of the stop lamp unit 31 and the tail lamp unit 32 can be improved.

As shown in fig. 8, the tail lamp unit 3 is preferably disposed above the left winker unit 4 and the right winker unit 5. More specifically, it is preferable that the stop lamp light source 31a and the tail lamp light source 32a of the tail lamp unit 3 are located above the left winker unit 4 and the right winker unit 5, the stop lamp facing portion 37 is located above the left winker unit 4 and the right winker unit 5, and the tail lamp facing portion 38 is also located above the left winker unit 4 and the right winker unit 5. Thus, the tail lamp unit 3 is less likely to be interfered by the light from the winker lamp units 4 and 5, and hence the visibility of the stop lamp unit 31 and the tail lamp unit 32 can be improved.

As shown in fig. 8, the tail light unit 3 is preferably disposed forward of the rearmost end of the rear wheel of the vehicle and forward of the rear end point 24b of the rear housing portion 24. This can shorten the dimension of the vehicle in the front-rear direction, and improve the mobility of the vehicle.

5. Tail lamp unit housing part 25

As shown in fig. 6(a) and 6(b), the tail lamp unit accommodating portion 25 includes a peripheral wall portion 26, a rear edge portion 27, and a base end portion 28. The base end portion 28 is adjacent to the rear housing portion 24 of the rear body housing RC. The base end portion 28 is located at the forefront of the tail lamp unit accommodating portion 25, and is formed continuously with a portion of the rear shell portion 24 of the rear body shell RC adjacent to the tail lamp unit accommodating portion 25, preferably the base end portion 28 forms a continuous curved surface with a portion of the rear shell portion 24 of the rear body shell RC adjacent to the tail lamp unit accommodating portion 25, and more preferably the base end portion 28 has the same center of curvature as a portion of the rear shell portion 24 of the rear body shell RC adjacent to the tail lamp unit accommodating portion 25. The peripheral wall portion 26 protrudes rearward with respect to the surface of the rear body shell RC. More specifically, the peripheral wall portion 26 is formed to protrude rearward from the rear end of the base end portion 28. At this time, as shown in fig. 6(a), in a side view of the vehicle, the average inclination angle θ 1 of the upper edge of the peripheral wall portion 26 with respect to the horizontal line is smaller than the average inclination angle θ 2 of the upper edge of the base end portion 28 with respect to the horizontal line. Here, the average inclination angle θ 1 of the upper edge of the peripheral wall portion 26 refers to an inclination angle of a straight line connecting the front end and the rear end of the upper edge of the peripheral wall portion 26 (a dotted line at the peripheral wall portion 26 in fig. 6 a) with respect to a horizontal line in a vehicle side view, and the average inclination angle θ 2 of the upper edge of the base end portion 28 refers to an inclination angle of a straight line connecting the front end and the rear end of the upper edge of the base end portion 28 (a dotted line at the base end portion 28 in fig. 6 a) with respect to a horizontal line in a vehicle side view. As shown in fig. 6(b), in a vehicle plan view, the average inclination angle θ 3 of the side edge of the peripheral wall portion 26 with respect to the horizontal line is smaller than the average inclination angle θ 4 of the side edge of the base end portion 28 with respect to the horizontal line. Here, the average inclination angle θ 3 of the side edge of the peripheral wall portion 26 refers to an inclination angle of a straight line connecting the front end and the rear end of the side edge of the peripheral wall portion 26 (a dotted line at the peripheral wall portion 26 in fig. 6 (b)) with respect to a horizontal line in a vehicle plan view, and the average inclination angle θ 4 of the side edge of the base end portion 28 refers to an inclination angle of a straight line connecting the front end and the rear end of the side edge of the base end portion 28 (a dotted line at the base end portion 28 in fig. 6 (b)) with respect to a horizontal line in a vehicle plan view.

That is, both the base end portion 28 and the peripheral wall portion 26 are formed so as to be located further toward the rear inside the tail lamp unit housing portion 25, a turning point exists between the base end portion 28 and the peripheral wall portion 26, and the curved surface of the peripheral wall portion 26 and the curved surface of the base end portion 28 do not have the same center of curvature.

As shown in fig. 5(a) to 5(c), the peripheral wall 26 is formed continuously at least on the left, upper, and right sides of the tail light unit 3. As shown in fig. 6(a) and 6(b), the peripheral wall 26 extends rearward from the rear end of the base end 28 and toward the inside of the tail lamp unit housing portion 25. In other words, the peripheral wall portion 26 extends rearward so as to gradually approach a central axis parallel to the front-rear direction of the light irradiation surface 35 of the tail lamp unit 3 from the rear end of the base end portion 28.

As shown in fig. 6(a) and 6(b), the rear end of the peripheral wall 26 has a rear edge 27. The rear edge portion 27 extends from the rear end of the peripheral wall portion 26 toward the inside of the tail lamp unit housing portion 25 to a tail lamp facing portion 38, and has a light-shielding translucent cover peripheral wall portion 36 and a surface substantially perpendicular to the irradiation direction of the tail lamp unit 3 in the vehicle rear view. In other words, the rear edge portion 27 extends so as to approach from the rear end of the peripheral wall portion 26 toward the center of the light irradiation surface 35 of the tail lamp unit 3.

As shown in fig. 6(a) and 8, the length of the upper edge of the peripheral wall portion 26 located above in the front-rear direction is longest.

As shown in fig. 6(a) and 6(b), a fitting edge portion k1 extending forward is provided at the end of the rear edge portion 27 of the tail lamp unit accommodating portion 25 that faces the tail lamp facing portion 38. In contrast, a fitting recess k2 capable of fitting with the fitting edge k1 is provided at a position of the light-transmitting cover 34 facing the fitting edge k 1. The outer peripheral flange portion 38g described above constitutes a part of the fitting recess k 2. Thus, when the tail lamp unit 3 is mounted in the tail lamp unit housing portion 25, the tail lamp unit 3 can be easily mounted in the tail lamp unit housing portion 25 simply by fitting the fitting edge portion k1 into the fitting recess k 2.

As shown in fig. 5(a) and 5(b), the peripheral wall 26 of the tail lamp unit accommodating portion 25 is formed continuously at least on the left, upper, and right sides of the tail lamp unit 3. The peripheral wall 26 is disposed at least at a position separating the left diffusing member 32bl and the left winker 4 and at a position separating the right diffusing member 32br and the right winker 5 in the rear view of the vehicle.

As shown in fig. 8, in a vehicle side view, the peripheral wall portion 26 of the tail lamp unit accommodating portion 25 protrudes rearward beyond the rear ends of the left turn lamp unit 4 and the right turn lamp unit 5. As shown in fig. 6(b) or 7, the peripheral wall 26 of the tail lamp unit accommodating portion 25 is arranged to shield the light irradiation surface 35 from a vehicle side view. The rear edge portion 27 is disposed rearward of the light irradiation surface 35 in the vehicle side view. In other words, the light irradiation surface 35 is disposed so as not to protrude rearward from the rear edge portion 27 in a vehicle side view. That is, the light irradiation surface 35 is disposed so as to be invisible from the side of the vehicle.

As shown in fig. 2 and 5(a) to 5(c), the peripheral wall portion 26 forms a "dark area" in the tail lamp unit housing portion 25 because it is difficult for any of the left and right turn lamp portions 4 and 5 on the left and right sides to emit light, and stray light from a street lamp or the like above the saddle-riding type vehicle to enter the tail lamp unit housing portion 25. Since the diffusion member 32b of the tail lamp unit 32 is located in the "dark area", the luminance of the tail lamp unit 32 when it is turned on can be easily seen.

As shown in fig. 7 and 8, the position of the substrate 39 supporting the stop lamp light source 31a and the tail lamp light source 32a may be set to substantially coincide with the position of the connection between the peripheral wall portion 26 and the base end portion 28 in the front-rear direction (i.e., the starting point at which the peripheral wall portion 26 protrudes rearward from the base end portion 28). The base 33 of the tail lamp unit 3 is located forward of the peripheral wall 26 of the tail lamp unit accommodating portion 25 and substantially coincides with the base end 28 in the front-rear direction.

With this arrangement, the base 33 in front of the substrate 39 supporting the stop lamp light sources 31a and the tail lamp light sources 32a is positioned inside the base end portion 28 having a wider internal space than the peripheral wall portion 26, so that the heat accumulated in the substrate 39 can be efficiently dissipated.

6. Variation example

While various embodiments of the present invention have been described above, the present invention is not limited to the embodiments, and various design changes can be made as described below.

6.1 design Change of body Shell

In the above description, the rear body cover RC is configured by assembling the left and right side cover portions 23 and the rear cover portion 24 as separate members, but the left and right side cover portions 23 and the rear cover portion 24 may be integrally formed as the rear body cover RC. The rear body cover RC may be formed entirely of 2 left and right cover members, or may be formed by arbitrarily dividing the left and right side cover portions 23 and the rear cover portion 24 into two parts and then assembling the two parts.

6.2 design Change of taillight Unit

In the above description, the shape of the tail light unit is exemplified as being substantially circular, but the shape is not limited to this, and may be, for example, a substantially elliptical shape, a square shape, a diamond shape, or the like. In the above description, the annular diffusion member 32b is exemplified by a substantially circular ring shape, but the present invention is not limited to this, and for example, the annular member may be formed into a substantially elliptical, square, or diamond-shaped ring shape. In the above description, the outer peripheral contour of the light irradiation surface 35 of the tail light unit 3 is described as being substantially circular, but the invention is not limited thereto, and may be formed in a shape such as oval, square, or diamond.

Although the above description has been given using LEDs as the stop lamp light source 31a and the tail lamp light source 32a, the LEDs are not limited to LEDs, and other light sources such as a bulb may be used. In the example of fig. 4, a plurality of LEDs as the stop lamp light source 31a are arranged in a rectangular shape, but the arrangement is not limited thereto, and the arrangement may be in a circular shape, a linear shape, a rhombic shape, or the like.

6.3 design modification of taillight unit housing part

In the above description, the tail lamp unit accommodating portion 25 is integrally formed with the rear housing portion 24 of the rear body housing RC, but the two may be separate bodies. In other words, the tail lamp unit housing portion 25 may be provided to the rear housing portion 24 so as to be integrally formed with the rear housing portion 24, or may be configured by attaching a member separate from the rear housing portion 24 to the rear housing portion 24. The peripheral wall 26, the base end 28, and the rear edge 27 of the tail lamp unit housing portion 25 may be integrated or may be separate.

In the above description, the shape of the tail lamp unit receiving portion 25 is exemplified as being substantially circular in the vehicle rear view, but the shape is not limited to this, and may be, for example, substantially elliptical, square, or arched.

In the above description, the upper edge positioned above in the peripheral wall portion 26 of the tail lamp unit accommodating portion 25 has the longest length in the front-rear direction, but the length of the upper edge positioned above in the front-rear direction may be set to be the same as or shorter than the length of the lower edge positioned below in the front-rear direction in accordance with the design of the vehicle or the rear body housing RC.

Although the tail lamp unit accommodating portion 25 is provided in the rear housing portion 24 of the rear body housing RC in the above description, if the rear body housing RC is formed by 2 left and right cover members, the tail lamp unit accommodating portion 25 may be provided so as to straddle 2 left and right cover members forming the rear housing portion 24 in the rear body housing RC. In this case, the tail lamp unit accommodating portion 25 may be provided so as to straddle the left and right 2 cover members, or the tail lamp unit accommodating portion 25 may be formed by joining the left and right 2 cover members to each other.

Although the tail lamp unit accommodating portion 25 accommodates only a part of the tail lamp unit 3 in the above description, the tail lamp unit 3 may be entirely accommodated in the tail lamp unit accommodating portion 25, or the tail lamp unit 3 may be entirely accommodated in the peripheral wall portion 26 of the tail lamp unit accommodating portion 25.

In the present invention, the proximal end portion 28 may be omitted. That is, the tail lamp unit accommodating portion 25 may be configured to have only the peripheral wall portion 26 and the rear edge portion 27 without having the base end portion 28. At this time, the peripheral wall portion 26 protrudes rearward from the surface of the rear body shell RC, that is, the peripheral wall portion 26 is adjacent to the rear shell portion 24 of the rear body shell RC, there is a turning point between the rear shell portion 24 and the peripheral wall portion 26, and the curved surface of the peripheral wall portion 26 and the curved surface of the rear shell portion 24 do not have the same center of curvature. In this case, the other structure of the tail lamp unit housing portion 25 and the other structure of the present invention including the tail lamp unit 3 are not affected. When the base end portion 28 is omitted, the peripheral wall portion 26 extends rearward from the adjacent rear housing portion 24 so as to gradually approach the central axis of the light irradiation surface 35 of the tail lamp unit 3 parallel to the front-rear direction.

6.4 design modification of light irradiation surface

Fig. 9 shows a modification of fig. 6(b) of the present invention. The tail lamp unit accommodating portion 25' shown in fig. 9 includes a flange portion 29 in addition to the peripheral wall portion 26, the rear edge portion 27, and the base end portion 28. The flange portion 29 extends from the end portion of the rear edge portion 27 facing the tail lamp facing portion 38 toward the center of the light irradiation surface 35, and the flange portion 29 has a surface substantially perpendicular to the irradiation direction of the tail lamp unit 3 and shields a part of the outer peripheral portion of the tail lamp facing portion 38 in the vehicle rear view. Due to the presence of the flange portion 29, the light irradiation surface 35' of the light-transmitting cover 34, which allows the light emitted from the stop lamp 31 and the tail lamp 32 to pass through toward the outside of the vehicle body in the rear view of the vehicle, is smaller than the range including the stop lamp facing portion 37 and the tail lamp facing portion 38.

In the above description, the stop lamp facing portion 37 and the tail lamp facing portion 38 are exemplified as the light irradiation surface 35 of the light-transmitting cover 34 being integrally formed, but they may be separate bodies.

6.5 design Change of positional relationship among Tail light Unit, Turn light Unit, and Tail light Unit housing portion

In the above description, the left and right winker units 4 and 5 are disposed below the tail lamp unit 3, but the left and right winker units 4 and 5 may be disposed above the tail lamp unit 3 or at substantially the same height.

In fig. 2, the tail lamp unit accommodating portion 25 is disposed at a position rearward of the rear end of the seat portion 9, but the tail lamp unit accommodating portion 25 may be disposed at a position forward of the rear end of the seat portion 9 when the seat portion 9 is designed to be longer.

The saddle-riding vehicle 1 according to the present invention is not limited to a scooter type vehicle, and may be another type of saddle-riding vehicle. In addition, the present invention is not limited to the two-wheeled vehicle, but is also applicable to a scooter-type vehicle or other straddle-type vehicles in the form of three-wheeled vehicles. The present invention is also applicable to a saddle-ride type Vehicle other than a scooter type Vehicle such as an electric Vehicle, a sport type Vehicle, a light Vehicle with a pedal, a four-wheeled off-road Vehicle such as an ATV (All Terrain Vehicle). The electric motorcycle is not limited to a two-wheeled vehicle, and includes a three-wheeled vehicle. Further, in the case of an electric vehicle, the power unit is a motor rather than an engine.

7. Technical effects of the embodiments

A saddle-riding vehicle 1 according to embodiment 1 of the present invention is characterized by comprising: a rear body cover RC disposed at a rear portion of a vehicle body, a tail lamp unit 3 disposed at the rear body cover RC, a left turn lamp unit 4 disposed at the rear body cover RC and located more leftward than the tail lamp unit 3, and a right turn lamp unit 5 disposed at the rear body cover RC and located more rightward than the tail lamp unit 3; the tail light unit 3 includes: a stop lamp unit 31 that is disposed at the center in the lateral direction and is turned on in association with a brake operation, a tail lamp unit 32 that can be turned on during traveling, a base 33 that holds the stop lamp unit 31 and the tail lamp unit 32, and a translucent cover 34 that is disposed behind the base 33 and is separate from the base 33; the light-transmitting cover 34 has a light-irradiating surface 35 through which light emitted from the stop lamp unit 31 and the tail lamp unit 32 is irradiated toward the outside of the vehicle body; the tail lamp part 32 has a left diffusion member 32bl disposed at least between the stop lamp part 31 and the left turn lamp part 4 in a vehicle rear view and a right diffusion member 32br disposed at least between the stop lamp part 31 and the right turn lamp part 5; the rear body shell RC is provided with a tail lamp unit accommodating portion 25 that accommodates at least a part of the tail lamp unit 3; the tail lamp unit accommodating portion 25 has a peripheral wall portion 26 that protrudes rearward with respect to the surface of the rear body cover RC and is formed continuously at least on the left, upper, and right sides of the tail lamp unit 3; the peripheral wall portion 26 is disposed at least at a position separating the left diffusion member 32bl from the left winker portion 4 and at a position separating the right diffusion member 32br from the right winker portion 5, protrudes rearward from the rear end of each of the left winker portion 4 and the right winker portion 5 in a vehicle side view, and shields the light irradiation surface 35 in the vehicle side view.

According to embodiment 1 of the present invention, the stop lamp unit 31 is disposed at the center in the lateral direction, and the stop lamp unit 31 and the turn lamp units 4 and 5 are disposed as far apart as possible while suppressing an increase in size of the rear portion of the vehicle, thereby greatly reducing the degree of interference with each other at the time of lighting.

The tail lamp unit 32 has a left diffusion member 32bl disposed at least between the stop lamp unit 31 and the left turn lamp unit 4 in the rear view of the vehicle, and a right diffusion member 32br disposed at least between the stop lamp unit 31 and the right turn lamp unit 5. Thus, even if the brightness of the stop lamp unit 31 when turned on is substantially the same as the brightness of the winker lamp units 4 and 5 when turned on, the tail lamp unit 32 having relatively dark brightness and clearly concentrated light emission ranges is interposed between the two, so that the visibility of the light emission ranges of the stop lamp unit 31 when turned on simultaneously with the winker lamp units 4 and 5 can be improved.

The tail lamp unit housing portion 25 has a peripheral wall portion 26 that protrudes rearward from the surface of the rear body cover RC and is formed continuously at least on the left, upper, and right sides of the tail lamp unit 3, and the peripheral wall portion 26 is disposed at least at a position that separates the left diffusion member 32bl from the left winker portion 4 and at a position that separates the right diffusion member 32br from the right winker portion 5, protrudes rearward from the rear ends of the left winker portion 4 and the right winker portion 5 in the vehicle side view, and shields the light irradiation surface 35 in the vehicle side view. Even if the turn signal lamp portions 4 and 5 positioned on the left and right sides are turned on or stray light emitted from a street lamp or the like is irradiated from above the straddle-type vehicle 1, the peripheral wall portion 26 hardly enters the tail lamp unit accommodating portion 25, and thus a "dark area" is formed in the tail lamp unit accommodating portion 25. Since the diffusion member 32b of the tail lamp unit 32 is located in the "dark area", the luminance of the tail lamp unit 32 when it is turned on can be easily seen.

In particular, in the vehicle side view, the peripheral wall portion 26 shields not only the diffusion member 32b of the tail lamp portion 32 but also the light irradiation surface 35 of the light-transmitting cover 34 through which light from the tail lamp unit 3 passes, so that light refracted, reflected, or scattered at the light-transmitting cover 34 cannot be scattered toward the outer periphery of the tail lamp unit 3. Accordingly, the light emission range of the tail lamp unit 3 in the vehicle rear view substantially matches the area of the translucent cover 34 in the vehicle rear view, and the visibility of the light emission range of the tail lamp unit 32 can be improved because the light interference from the winker lamp units 4 and 5 is not received.

Therefore, according to embodiment 1 of the present invention, it is possible to provide a straddle-type vehicle in which the visibility of the light emission ranges of the stop lamp portion 31 and the turn lamp portions 4 and 5 and the visibility of the light emission range of the tail lamp portion 32 are improved, respectively, while suppressing an increase in size of the rear portion of the vehicle.

In embodiment 2 of the present invention, the stop lamp unit 31 has a stop lamp light source 31a that is directed in the irradiation direction of the tail lamp unit 3; the tail lamp unit 32 has a tail lamp light source 32a that emits light in the same direction as the stop lamp light source 31 a.

According to embodiment 2 of the present invention, the tail light source 32a of the tail light unit 32 is directed in the same irradiation direction as the stop light source 31a of the stop light unit 31. Thus, the tail lamp unit 32 does not need to have a space for reflecting light, and the front-rear direction dimensions of the tail lamp unit 3 and the tail lamp unit accommodating portion 25 can be shortened. Therefore, the dimension of the vehicle in the front-rear direction can be shortened, and the mobility of the vehicle can be improved.

In the saddle-riding vehicle according to embodiment 3 of the present invention, the stop lamp portion 31 includes an extension portion 31b that surrounds the stop lamp light source 31a and extends rearward; the left diffusing member 32bl and the right diffusing member 32br are disposed at substantially the same positions as the rear edge of the extension 31b in the front-rear direction.

According to embodiment 3 of the present invention, the stop lamp light source 31a is disposed further forward than the diffusion member 32b of the tail lamp unit 32, that is, at a relatively rear position in the tail lamp unit 3. Thus, the light of the stop lamp unit 31 is restricted by the extension 31b and is not scattered in the outer circumferential direction, and the boundary of the light is more clear. In other words, the diffusion member 32b of the tail lamp unit 32 is less likely to be interfered with by light from the stop lamp unit 31 when the stop lamp unit 31 is lit, and the light emission range of the stop lamp unit 31 can be clearly distinguished from the light emission range of the tail lamp unit 32 when viewed from the rear of the vehicle. Therefore, the visibility of the light emission range of the tail lamp unit 32 can be further improved.

In the saddle-riding vehicle according to embodiment 4 of the present invention, the light-transmitting cover 34 includes a stop lamp facing portion 37 facing the stop lamp light source 31a, and a tail lamp facing portion 38 facing the left diffusion member 32bl and the right diffusion member 32 br; the tail lamp facing portion 38 is disposed rearward of the stop lamp facing portion 37.

According to the 4 th embodiment of the present invention, since the tail lamp facing portion 38 is disposed rearward of the stop lamp facing portion 37, when the light from the stop lamp light source 31a passes through the stop lamp facing portion 37 of the light-transmitting cover 34, the light refracted, reflected, or scattered at the stop lamp facing portion 37 and the light refracted, reflected, or scattered at the tail lamp facing portion 38 are separated in the front-rear direction. In other words, a region where light is hardly emitted is interposed between the stop lamp facing portion 37 and the tail lamp facing portion 38 in the front-rear direction of the light emitting region.

With this configuration, when viewed from diagonally behind the vehicle, the non-light-emitting region can separate the light-emitting region of the stop lamp facing portion 37 from the light-emitting region of the tail lamp facing portion 38, so that the stop lamp facing portion 37 and the tail lamp facing portion 38 can be more clearly distinguished. Therefore, the visibility of the light emission range of the tail lamp unit 32 can be further improved.

In the saddle-riding vehicle according to embodiment 5 of the present invention, the left turn lamp unit 4 has a left turn lamp translucent cover 41 through which light from the light source of the left turn lamp unit 4 passes, and the right turn lamp unit 5 has a right turn lamp translucent cover 51 through which light from the light source of the right turn lamp unit 5 passes; the area of the stop lamp opposing portion 37 is smaller than the area of each of the left and right turn lamp translucent covers 41 and 51 in the rear view of the vehicle.

According to the 5 th embodiment of the present invention, the area of the stop lamp opposing portion 37 is smaller than the area of each of the left and right winker translucent covers 41 and 51 in the vehicle rear view, and the degree of interference between them can be reduced. Therefore, the visibility between the light emission range of the stop lamp unit 31 and the light emission ranges of the winker lamp units 4 and 5 can be further improved while suppressing an increase in size of the rear portion of the vehicle.

In the saddle-riding vehicle according to embodiment 6 of the present invention, the light-transmitting cover 34 has a light-transmitting cover peripheral wall portion 36 extending forward from the outer periphery of the tail lamp facing portion 38, and the tail lamp unit accommodating portion 25 has a rear edge portion 27 extending inward of the tail lamp unit accommodating portion 25 from the peripheral wall portion 36 and shielding the light-transmitting cover peripheral wall portion 36 from the rear view of the vehicle.

According to the 6 th embodiment of the present invention, the tail lamp unit accommodating portion 25 has the rear edge portion 27 that extends from the peripheral wall portion 26 toward the inside of the tail lamp unit accommodating portion 25 and that shields the light-transmitting cover peripheral wall portion 36 from the rear view of the vehicle. Thus, even if the "dark area" formed by the peripheral wall portion 26 of the tail lamp unit housing portion 25 receives light from the vehicle obliquely rearward by irradiation of another vehicle, the rear edge portion 27 can shield a part of the light, and the darkness of the "dark area" can be maintained more reliably. Therefore, the visibility of the light emission range of the tail lamp unit 32 can be further improved.

In the saddle-riding vehicle according to embodiment 7 of the present invention, the tail lamp unit accommodating portion 25 'has a flange portion 29 that extends from the rear edge portion 27 toward the inside of the tail lamp unit accommodating portion 25' and that shields a part of the tail lamp facing portion 38 from the rear view of the vehicle.

According to the 7 th embodiment of the present invention, the tail lamp unit accommodating portion 25 'has a flange portion 29 that extends from the rear edge portion 27 toward the inside of the tail lamp unit accommodating portion 25' and that shields a part of the tail lamp facing portion 38 from the rear view of the vehicle. Thus, even if the "dark area" formed by the peripheral wall portion 26 of the tail lamp unit housing portion 25' receives light from the diagonally rear side of the vehicle due to the irradiation of another vehicle, the flange portion 29 can shield a part of the light, and the darkness of the "dark area" can be maintained more reliably. Therefore, the visibility of the light emission range of the tail lamp unit 32 can be further improved.

In the saddle-riding vehicle according to embodiment 8 of the present invention, the tail lamp facing portion 38, the left diffusing member 32bl, and the right diffusing member 32br are arranged so as to be located more rearward as they go to the outer periphery.

According to embodiment 8 of the present invention, since the tail lamp facing portion 38, the left diffusion member 32bl, and the right diffusion member 32br are disposed so as to be located more rearward as they go to the outer periphery, the stop lamp facing portion 37 and the stop lamp light source 31a can be easily viewed from diagonally rearward of the vehicle even if the light emitting area of the stop lamp portion 31 is small. Therefore, the visibility of the light emission range of the stop lamp unit 31 can be further ensured.

In the saddle-riding type vehicle according to embodiment 9 of the present invention, the tail lamp unit 3 has a substantially circular shape in a rear view of the vehicle.

According to the 9 th embodiment of the present invention, since the shape of the tail lamp unit 3 is substantially circular, the area is smaller than that of a quadrangle having the same vertical dimension and the same horizontal dimension, but the visibility from the rear view of the vehicle is substantially the same, and therefore the number of lamps can be reduced, and the rear body cover RC can be further downsized.

In the saddle-riding vehicle according to embodiment 10 of the present invention, the left diffusion member 32bl and the right diffusion member 32br are annularly formed so as to surround the stop lamp light source 31a in a rear view of the vehicle.

According to the 10 th embodiment of the present invention, the left diffusion member 32bl and the right diffusion member 32br are formed in an annular shape so as to surround the stop lamp light source 31a in a rear view of the vehicle. Thus, the stop lamp light source 31a can be completely surrounded by the diffusion member 32b, which makes the boundary of light most clear, and therefore, visibility of the stop lamp unit 31 in the rear view of the vehicle can be further improved.
