Technical Field

The present invention relates to a vehicle wheel including a wheel main body and an annular decorative member detachably attached to the wheel main body.

Background

A wheel for a vehicle has a wheel body having a rim and a spoke. As a vehicle wheel that does not come off and that achieves improvement in aerodynamic performance without losing appearance, there is known a vehicle wheel that includes: a wheel body; and a flow regulating plate for regulating an air flow flowing on the wheel surface side when the vehicle is running (patent document 1). In this vehicle wheel, the rectifying plate is formed in a ring plate shape covering a spoke outer diameter region (outer peripheral portion) on the design surface side (outer surface side of the wheel body) of the spoke, and the outer peripheral edge portion of the rectifying plate is joined to an outer rim flange, which is a vehicle outer portion, of the rim by friction stir welding in the circumferential direction. In addition, in embodiment 3 of patent document 1 (fig. 9 and 10), an annular fitting groove portion having a width corresponding to the radial width of the rectifying plate and a depth corresponding to the plate thickness of the rectifying plate is formed over the entire circumferential region on the design surface including the spoke portion of the spoke. The rectifying plate is fitted in the fitting groove portion, joined to the outer rim flange at the outer peripheral edge by friction stir welding, and further joined to the spoke portion at the inner peripheral edge.

Further, the following structure is known for an automobile wheel: the trim ring is provided to be detachable from the front surface (outer surface) side of the wheel body with respect to the outer peripheral portion of the wheel body (patent document 2). In this vehicle wheel, an inwardly projecting flange portion that projects radially inward is provided on a rim flange on an outer surface side of a wheel main body. The decorative ring integrally has a plurality of insertion legs, and distal end portions of the insertion legs have wedge claws bulging toward the radially outer side. The decorative ring is mounted to the stationary wheel main body by elastically receiving a support ring made of a metal wire provided on the radially inner side by an insertion leg and engaging a wedge claw with the inwardly projecting flange portion.

Disclosure of Invention

In view of such a background, an object of the present invention is to provide a vehicle wheel: the outer member constituting the decorative member can be reliably attached to the wheel main body in a detachable manner without complicating the manufacturing and the attachment, and the rigidity of the spoke can be prevented from being lowered.

In order to solve the above problem, one embodiment of the present invention is a vehicle wheel 1 including a wheel body 2, the wheel body 2 including a hub mounting portion 6, a plurality of spokes 7 radially extending from the hub mounting portion, and a cylindrical rim 5 coupled to radially outer ends of the spokes, the vehicle wheel 1 including: a ring-shaped outer member 11 disposed along an inner periphery of the rim on an outer surface side of the wheel body with respect to the spokes; and an annular inner member 12 disposed along an inner periphery of the rim on an inner surface side of the wheel main body with respect to the spokes, wherein an annular recessed portion 10 is formed over an entire circumference of an outer surface side portion of the outer end of the rim and/or the spokes, the outer member has an annular protrusion 13a fitted into the annular recessed portion, and the outer member and the inner member have coupling means 18 for detachably coupling to each other.

According to this configuration, the outer member is coupled to the inner member via the coupling means, so that the outer member is detachably attached to the wheel main body in a state where the outer member cooperates with the inner member to sandwich the plurality of spokes. Therefore, the outer member can be reliably attached to the wheel main body without falling off. Further, since the outer member is attached to the wheel main body by being coupled to the inner member, it is not necessary to form the wheel main body into a special shape such as an undercut shape. Therefore, the manufacture of the wheel main body is not complicated. In addition, the outer member can be attached to the wheel main body by an easy work of coupling the inner member to the coupling means, and the outer member is an annular integrated body having the annular protrusion, so that the attachment of the outer member is not complicated. Further, the annular recessed portion into which the annular protrusion is fitted is formed in the outer surface side portion of the outer end of the rim and/or the spoke, which has less influence on rigidity and strength, and therefore, a decrease in rigidity of the spoke is suppressed.

In the above configuration, the outer member 11 may include: a plurality of plate portions 14 located between the spokes 7; and a ring portion 13 connecting the plate portions, the annular projection 13a being provided on the ring portion.

According to this structure, the wheel body can be decorated with the plurality of plate portions. Therefore, the appearance and design of the vehicle wheel can be improved.

In the above configuration, substantially the entire ring portion 13 may be immersed in the annular recess 10.

According to this structure, the wind flowing along the outer surface of the wheel main body is not disturbed by the ring portion. Therefore, the aerodynamic performance of the vehicle wheel can be improved.

In the above configuration, the plate portion 14 may be located on an imaginary plane 15 defined by outer surface side contours of the spokes 7 adjacent in the circumferential direction, or may be located inside the imaginary plane.

According to this configuration, the plate portion does not protrude from the virtual surface, and therefore handling of the vehicle wheel is not complicated even in a state where the exterior member is attached.

In the above configuration, the outer member 11 may further include a center plate portion 71 that connects radially inner ends of the plurality of plate portions 14.

According to this structure, the area of the outer member is increased, and therefore, the appearance and design of the vehicle wheel can be made different. Further, since the plurality of plate portions are connected by the center plate portion, the rigidity of the plurality of plate portions is improved.

In the above configuration, the vehicle wheel 1 may further include a center cover 75, the center cover 75 may be inserted into a boss hole 8 formed in an axis of the boss mounting portion 6, and the center plate portion 71 may be held in an annular shape by the center cover.

According to this structure, the center plate portion is held by the hub mounting portion through the center cover, so that looseness and vibration of the center plate portion and the plurality of plate portions are suppressed.

In the above configuration, the coupling means 18 may include a plurality of coupling portions 19, and the plurality of coupling portions 19 may be integrally provided on the inner surface side of the plurality of plate portions 14 to be coupled to the inner part 21.

According to this configuration, the degree of freedom in designing the coupling portion can be improved as compared with a case where the coupling portion is provided in the ring portion.

In the above configuration, the coupling means 18 may include: a plurality of screw members 34 inserted into a plurality of through holes 33 formed in the inner member 12; and a plurality of screw holes 35 having bottoms, which are formed on the inner surface side of the coupling portion 19 so as to be screwed with the screw members.

According to this configuration, the outer member can be reliably coupled to the inner member by the screw member.

In the above configuration, the coupling means 18 may include an engaging claw 45 integrally formed with the outer member 11 and engaged with the inner member 12.

According to this structure, the outer member can be joined to the inner member without using any other member.

In the above configuration, the coupling unit 18 may include a plurality of locking pieces 43, and the plurality of locking pieces 43 may be integrally provided to the inner part 12 so as to protrude outward and lock the plurality of engagement claws 45.

According to this structure, the inner member can be locked to the engagement claw at an outer position. Therefore, the engagement claw does not protrude inward from the inner member and interfere with the brake device.

Effects of the invention

Thus, according to the present invention, there is provided a vehicle wheel comprising: the outer member can be reliably detachably attached to the wheel main body without complicating the manufacturing and attachment, and the drop-off can be avoided, and the reduction in the rigidity of the spokes can be suppressed.

Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following description, the exterior surface of the vehicle wheel 1 (i.e., the surface on the outer side in the vehicle width direction) is referred to as the front surface, the front surface side of the vehicle wheel 1 is referred to as the outer side, and the back surface side of the vehicle wheel 1 is referred to as the inner side.

EXAMPLE 1 embodiment

First, embodiment 1 of the present invention will be described with reference to fig. 1 to 6. As shown in fig. 1 and 2, a vehicle wheel 1 includes a cylindrical wheel body 2 that holds a tire. The wheel main body 2 is a one-piece wheel made of light metal such as aluminum alloy or magnesium alloy, and is formed by casting, forging, press forming, or the like.

The wheel main body 2 has: a wheel disc 4 mounted to a hub 3 of a vehicle (see fig. 4); and a cylindrical rim 5 integrally provided on an outer peripheral portion of the spoke 4. The spoke 4 has: a hub mounting portion 6 disposed at the center in the radial direction; and a plurality of spokes 7 radially extending from an outer peripheral portion of the hub mounting portion 6. The radially outer ends of the spokes 7 are joined to the inner periphery of the rim 5.

The hub mounting portion 6 is formed in a ring shape having a hub hole 8 formed on the axis thereof, and a plurality of bolt holes 9 are formed around the hub hole 8 of the hub mounting portion 6. The plurality of spokes 7 may have the same shape or different shapes. The plurality of spokes 7 may have a linear shape, a curved shape, a twisted shape, or the like. In the present embodiment, 5 linear spokes 7 are arranged at equal intervals in the circumferential direction, and the spokes 4 have a rotationally symmetrical shape.

At the outer surface side portion of the coupling portion of the rim 5 to the spokes 7, an annular recess 10 is formed over the entire circumference of the rim 5. The annular recess 10 is in the form of a U-shaped cross-sectional groove open to the outer surface side at the radially outer end of the spoke 7 at the junction of the rim 5 and the spoke 7. The annular recess 10 is a recess having an L-shaped cross section that opens to the outer surface side and the radial inner side at a portion of the rim 5 to which the spokes 7 are not connected.

On the outer surface side of the wheel main body 2 (more specifically, the outer surface side of the plurality of spokes 7), a ring-shaped outer member 11 as an external member is disposed coaxially with the wheel main body 2. On the other hand, an annular inner member 12 is disposed coaxially with the wheel main body 2 on the inner surface side of the wheel main body 2 (more specifically, on the inner surface side of the spokes 7). The inner part 12 and the outer part 11 are injection-molded articles made of a resin material, and the outer part 11 is attached to the wheel main body 2 by being joined to the inner part 12. In other embodiments, the inner part 12 or the outer part 11 can also be made of metal. The external member 11 may be coated or plated to improve the appearance.

As shown in fig. 3 and 4, the outer member 11 is disposed on the outer surface side of the spokes 7 to constitute a decorative member. The outer member 11 has an annular ring portion 13 and a plurality of plate portions 14 projecting radially inward from the ring portion 13. The ring portion 13 has an annular projection 13a projecting inward on the inner surface side. An annular projection 13a is formed over the entire circumference of the ring portion 13, and the annular projection 13a is fitted into the annular recess 10. In the present embodiment, the ring portion 13 is entirely submerged in the annular recessed portion 10. That is, the ring portion 13 constitutes the annular protrusion 13a as a whole.

Each plate portion 14 has a radial dimension smaller than the length dimension of the spokes 7 (i.e., has a projection length smaller than the radial dimension of the space between the spokes 7), and each plate portion 14 is disposed only on the outer peripheral portion of the plurality of spokes 7 between 1 pair of spokes 7 adjacent to each other in the circumferential direction. In the present embodiment, 5 plate portions 14 are formed in the outer member 11 in the same number as the spokes 7. Each plate portion 14 has: a flow rectification plate portion 16 provided along an imaginary surface 15 (imaginary spoke surface), the imaginary surface 15 being defined by outer surface side contours of 2 spokes 7 adjacent in the circumferential direction; and a flange portion 17 that protrudes inward from the peripheral edge of the flow rectification plate portion 16. In the present embodiment, the spokes 7 are linear, and therefore the flow straightening plate portions 16 of the plate portions 14 are flat plate-shaped. The flange portion 17 of the plate portion 14 is provided to surround the flow rectification plate portion 16 together with the ring portion 13, and reinforces the flow rectification plate portion 16. The outer surface of the ring portion 13 and the outer surfaces of the respective rectification plate portions 16 are located on the imaginary plane 15, and the ring portion 13 and the respective plate portions 14 are located inside the imaginary plane 15.

The outer member 11 and the inner member 12 are attached to the wheel main body 2 by being coupled to each other by coupling means 18 (coupling means), and the coupling means 18 is used to detachably couple the outer member 11 and the inner member 12 to each other. A plurality of coupling portions 19 for coupling with the inner member 12 are integrally provided on the inner surface side of the plurality of plate portions 14 of the outer member 11. In the present embodiment, 1 coupling portion 19 is provided for each plate portion 14.

As shown in fig. 4, an outer bead seat portion 22 having a larger diameter than the groove portion 21 is provided on the outer surface side of the groove portion 21 of the rim 5, and an outer rim flange 23 is provided on the outer surface side of the outer bead seat portion 22. An inner rim flange 24 is provided at an end portion on the inner surface side of the rim 5. A brake device 25 is disposed radially outward of the hub 3 and radially inward of the rim 5.

Each spoke 7 is coupled to the outer peripheral portion of the hub mounting portion 6 at the radially inner end and coupled to the outer bead seat portion 22 of the rim 5 at the radially outer end. Since the annular recess 10 is provided in the joint portion of the rim 5 with the spokes 7, the ring portion 13 of the outer member 11 that is submerged in the annular recess 10 has an inner diameter larger than the outer diameter of the inner member 12. The plurality of plate portions 14 (more specifically, the joint portions 19) of the outer member 11 are arranged facing each other on the outer surface side of the inner member 12.

The inner member 12 has: an inner body portion 31 which is an annular body portion; and a plurality of (5) corresponding coupling portions 32 integrally provided in the inner body portion 31 so as to protrude from the inner body portion 31 toward the outer surface side at positions corresponding to the plurality of coupling portions 19. The inner body portion 31 has a groove cross-sectional shape that opens to the inner surface side, and the inner body portion 31 is disposed in contact with the inner surfaces of the plurality of spokes 7. The inner body portion 31 may have the same outer diameter as the inner diameter of the groove portion 21 (minimum radius portion) of the rim 5. In this case, the inner body portion 31 is positioned in the radial direction by abutting against the inner surface of the rim 5. In this way, the inner body portion 31 is disposed in the outer peripheral portion that does not easily interfere with the brake device 25, and the degree of freedom in the cross-sectional shape of the inner body portion 31 is increased, so that the inner body portion 31 can be formed in a cross-sectional shape having a desired strength.

Each corresponding coupling portion 32 penetrates the inner body portion 31, and defines a through hole 33 extending from the inner body portion 31 to the outer surface side. The shaft of the screw member 34 (screw, bolt, or the like) is inserted into the through hole 33 from the inner surface side. The joint portion 19 of the outer member 11 defines a bottomed screw hole 35 that opens to the inner surface side for screwing with the screw member 34 inserted into the through hole 33 of the corresponding joint portion 32. The shaft portion of the screw member 34 penetrates the corresponding coupling portion 32 and is screwed into the screw hole 35 of the corresponding coupling portion 19. Thereby, the outer member 11 is coupled to the inner member 12, and the outer member 11 is detachably attached to the wheel main body 2 in a state where the plurality of spokes 7 are sandwiched in cooperation with the inner member 12. The coupling unit 18 is constituted by these coupling portions 19, corresponding coupling portions 32, and screw members 34.

In a state where the outer member 11 is attached to the wheel body 2, the outer surface of the ring portion 13 and the outer surface of the plate portion 14 are located on the imaginary plane 15, and the plate portion 14 does not protrude outward with respect to the imaginary plane 15. Therefore, even in a state where the outer part 11 is attached, the outer part 11 does not interfere with a device for replacing a tire or an auxiliary for alignment adjustment, and handling of the vehicle wheel 1 is not complicated. Further, even if the outer surface of the ring portion 13 or the plate portion 14 is located inward with respect to the virtual surface 15, the same effect can be achieved.

The order of mounting the outer member 11 to the wheel body 2 is as follows. As shown in fig. 5 and 6, first, the inner member 12 is disposed on the inner surface side of the plurality of spokes 7. The inner member 12 may be configured such that the corresponding joints 32 are located at the center of 1 circumferentially adjacent pair of spokes 7. Alternatively, the inner body 31 may be formed with positioning recesses corresponding to the spokes 7. Next, as shown in fig. 1 and 3, the outer member 11 is disposed on the outer surface side of the spoke 7. The outer member 11 is configured such that the annular protrusion 13a of the ring portion 13 is fitted in the annular recess 10 so as to be easily positioned with respect to the wheel body 2 in the radial direction. In addition, the outer member 11 is configured such that the plurality of plate portions 14 are located between the spokes 7 so as to be easily positioned relative to the wheel body 2 in the circumferential direction. Then, as shown in fig. 4, the plurality of screw members 34 are inserted into the through-holes 33 from the inner surface side of the inner member 12 and screwed into the screw holes 35 of the outer member 11. Thereby, the inner member 12 and the outer member 11 are coupled to each other, and the outer member 11 is attached to the wheel main body 2.

The vehicle wheel 1 is configured as described above. Therefore, the following effects can be achieved.

The outer member 11 is coupled to the inner member 12 via the coupling means 18, and the outer member 11 is detachably attached to the wheel main body 2. Therefore, the outer member 11 is reliably attached to the wheel main body 2 so as not to fall off. Further, since the outer member 11 is attached to the wheel main body 2 by being coupled to the inner member 12, it is not necessary to form the wheel main body 2 into a special shape such as an undercut shape. Therefore, the manufacture of the wheel main body 2 does not become complicated. In addition, the outer member 11 can be attached to the wheel main body 2 by an easy work of coupling the inner member 12 to the coupling means 18, and the outer member 11 is an annular integrated body having the ring portion 13, so that the attachment of the outer member 11 is not complicated. Further, the annular recessed portion 10 into which the annular protrusion 13a is fitted is formed on the outer surface side portion of the outer ends of the rim 5 and the spokes 7, which has little influence on the rigidity and strength, and therefore, a decrease in the rigidity of the spokes 7 is suppressed.

The outer member 11 has: a plurality of plate portions 14 located between 1 pair of spokes 7 adjacent to each other in the circumferential direction; and a ring portion 13 connecting the plurality of plate portions 14. Therefore, the wheel body 2 can be decorated with the plurality of plate portions 14, and the appearance and the aesthetic appearance of the vehicle wheel 1 can be improved.

The ring portion 13 is substantially entirely submerged in the annular recess 10, and does not protrude outward with respect to the virtual surface 15. Therefore, the wind flowing along the outer surface of the wheel main body 2 is not disturbed by the ring portion 13. This improves the aerodynamic performance of the vehicle wheel 1.

The coupling unit 18 includes a plurality of coupling portions 19, and the plurality of coupling portions 19 are integrally provided on the inner surface side of the plurality of plate portions 14 for coupling with the inner part 12. This improves the degree of freedom in designing the coupling portion 19, compared to the case where the coupling portion 19 is provided in the ring portion 13.

In addition, the binding unit 18 includes: a plurality of screw members 34 inserted into the plurality of through holes 33 formed in the inner member 12; and a bottomed screw hole 35 formed on the inner surface side of the coupling portion 19 so as to be screwed with the screw member 34. Thereby, the outer member 11 is reliably coupled to the inner member 12 by the screw member 34.

EXAMPLE 2 EXAMPLE

Next, embodiment 2 of the present invention will be described with reference to fig. 7 and 8. The same or similar elements as those in the above embodiment are denoted by the same reference numerals, and redundant description thereof is omitted. The same applies to the following embodiments. In the present embodiment, the structure of the coupling unit 18 is different from the above-described embodiments. The following description will be specifically made. Each corresponding coupling portion 32 of the inner part 12 is constituted by a locking piece 43 protruding outward from the inner body portion 31. The locking piece 43 is a plate piece having a radial dimension smaller than a circumferential dimension and capable of elastic deformation in the radial direction, and has a locking shoulder surface facing the inner surface side on the radially inner side of the tip. The coupling portion 19 of the outer member 11 protrudes inward from the inner surface of the corresponding plate portion 14, and has an engagement claw 45 that engages with the locking piece 43 of the inner member 12 on the radially outer side of the tip. The engaging claws 45 engage with the locking pieces 43 on the inner side of the corresponding plate portion 14 and on the outer side of the inner body portion 31 (i.e., between the plate portion 14 and the inner body portion 31).

As described above, in the present embodiment, since the coupling means 18 is formed integrally with the outer member 11 and includes the engagement claws 45 that engage with the inner member 12, the outer member 11 and the inner member 12 can be coupled without using another member like the screw member 34 of embodiment 1. Further, since the coupling unit 18 is provided integrally with the inner part 12 so as to protrude outward and includes the plurality of locking pieces 43 locked to the plurality of engaging claws 45, the engaging claws 45 are locked to the inner part 12 at a position outside the inner body portion 31. Therefore, the engagement claws 45 do not protrude further inward than the inner body portion 31 and interfere with the brake device 25 shown by imaginary lines in fig. 8.

EXAMPLE 3

Next, embodiment 3 of the present invention will be described with reference to fig. 9 and 10. In the present embodiment, the inner body portion 31 is formed to have a width wider than that of the above-described embodiment. That is, the inner diameter of the inner body portion 31 is smaller than that of the above embodiment. The coupling unit 18 includes a screw hole 35 provided in the outer member 11, which is similar to that of embodiment 1, and an engagement claw 45, which is similar to that of embodiment 2. The engagement claw 45 is formed on a radially outer surface (a surface opposite to the design surface) of the flange portion 17 of the plate portion 14. The coupling unit 18 includes a through hole 33 provided in the inner member 12, which is similar to that of embodiment 1, and a locking piece 43, which is similar to that of embodiment 2. The screw hole 35 and the through hole 33 corresponding to the screw hole 35 are provided radially outward, and the engaging claw 45 and the engaging piece 43 corresponding to the engaging claw 45 are provided radially inward and are longer in the circumferential direction than in the case of embodiment 2.

By adopting such a structure, the respective plate portions 14 of the outer member 11 are joined to the inner member 12 at two locations, radially outside and inside, and therefore the support rigidity of the plate portions 14 is improved. In particular, since the portion provided with the screw hole 35 and the through hole 33 is formed in a closed cross-sectional shape by the outer member 11 and the inner member 12 as shown in fig. 10, the support rigidity of the plate portion 14 is high. Further, the engagement claws 45 and the locking pieces 43 having a large circumferential length are provided on the radially inner side, which is the movable end side, so that the support rigidity of the plate portion 14 is higher than that in the case of the reverse arrangement.

Next, embodiment 4 of the present invention will be described with reference to fig. 11 and 12. In the present embodiment, the inner body portion 31 is formed to have a narrow width at a portion facing the spoke 7, and is formed to have a large width at a portion where the spoke 7 is not provided (a portion facing the plate portion 14 with a space interposed therebetween). In other words, the inner body portion 31 has an annular inner ring portion 53 and a plurality of inner plate portions 54 projecting radially inward from the inner ring portion 53. As shown in fig. 12, the inner plate portion 54 is disposed at a position overlapping the spokes 7 in the vehicle width direction (the left-right direction in fig. 12).

By configuring the inner part 12 in this manner, the inner plate portion 54 constituting the inner part of the inner part 12 in the radial direction does not protrude further inward than the spokes 7 and interfere with the brake device 25 shown by imaginary lines in fig. 12.

EXAMPLE 5 EXAMPLE

Next, embodiment 5 of the present invention will be described with reference to fig. 13 and 14. In the present embodiment, the inner member 12 is formed of a ring spring 61, and the ring spring 61 is formed of a metal wire having elasticity. The annular spring 61 has an outer diameter smaller than the inner diameter of the groove portion 21 of the rim 5, and is disposed so as to abut against the inner surfaces of the plurality of spokes 7 without abutting against the inner surface of the rim 5. The engaging claws 45 of the outer member 11 may have the same shape as in the above-described embodiment, or may have a hook shape as shown in fig. 14.

By configuring the vehicle wheel 1 in this way, the structure of the inner member 12 is simplified, and the inner member 12 is easily manufactured.

EXAMPLE 6 EXAMPLE

Finally, embodiment 6 of the present invention will be described with reference to fig. 15 and 16. In the present embodiment, the plate portion 14 of the outer member 11 is in the form of a spoke at the radially inner portion, and has a width narrower than the gap between the spokes 7, and a radial dimension longer than that of the above-described embodiment. The outer member 11 has a center plate portion 71 that connects the radially inner ends of the plurality of plate portions 14. The center plate portion 71 is annular corresponding to the annular hub attachment portion 6, and covers the hub attachment portion 6 from the outer surface side. Specifically, a center hole 72 matching the boss hole 8 is provided on the axis of the center plate portion 71, and a plurality of outer peripheral holes 73 matching the bolt holes 9 are formed around the center hole 72 of the center plate portion 71.

The vehicle wheel 1 has a center cover 75 inserted and fitted into the boss hole 8. The center cover 75 has a circular plate portion 76 disposed on the outer surface and a cylindrical portion 77 inserted into the boss hole 8, and the circular plate portion 76 is formed to have a larger diameter than the cylindrical portion 77. The center plate portion 71 of the outer member 11 is held by the hub attachment portion 6 of the wheel body 2 by a center cover 75 attached to the hub hole 8.

As described above, since the outer member 11 further includes the annular center plate portion 71 that connects the radially inner end portions of the plurality of plate portions 14, the area of the outer member 11 increases, and thus variations in the appearance and design of the vehicle wheel 1 can be caused. Further, since the plurality of plate portions 14 are connected by the center plate portion 71, the rigidity of the plurality of plate portions 14 is improved.

In addition, the center plate portion 71 is held by the center cover 75 to the hub mounting portion 6, so that looseness and vibration of the center plate portion 71 and the plurality of plate portions 14 are suppressed.

The vehicle wheel 1 according to the present invention can provide various types of outer members 11 having different shapes, colors, patterns, and the like, thereby providing various differences in the appearance and design of the 1 wheel main body 2. Further, by changing the outer member 11 attached to the wheel body 2, the appearance and design of 1 wheel body 2 can be changed according to preference and use.

While the specific embodiments have been described above, the present invention is not limited to the above embodiments, and can be widely modified and implemented. For example, in the above embodiment, the wheel main body 2 is a one-piece wheel, but may be a two-piece wheel or a three-piece wheel. In the above embodiment, the ring portion 13 is configured as the annular protrusion 13a as a whole, but the ring portion 13 may include a portion protruding from the annular recess 10 to the outer surface side (a portion protruding outward from the virtual surface 15). In the above embodiment, the joint portion 19 is provided in the plate portion 14 of the outer member 11, but the joint portion 19 may be provided in the ring portion 13 of the outer member 11. The specific structure, arrangement, number, material, and the like of each member and part can be appropriately changed without departing from the scope of the present invention. In addition, the above embodiments can be combined as appropriate. On the other hand, all of the components shown in the above embodiments are not necessarily essential and can be appropriately selected.
