[ problem to be solved by the invention ]

For example, in the case where the speed reduction mechanism does not have a worm gear that meshes with the driven gear, if the gear of the speed reduction mechanism is increased in size to obtain a desired gear ratio, the reel unit is increased in size.

The present invention has been made in an effort to provide a spinning reel that can tightly wind a fishing line around a spool while suppressing an increase in size of a reel unit.

[ solution for solving problems ]

A spinning reel according to an aspect of the present invention includes a reel unit, a spool shaft, a spool, a handle, a pinion, a 1 st intermediate gear, a 2 nd intermediate gear, and a reciprocating mechanism. The spool shaft is supported by the reel unit so as to be movable in the front-rear direction. The spool is connected to the spool shaft, and a fishing line is wound around the outer periphery thereof. The handle is rotatably supported by the reel unit. The pinion gear is rotatably supported by the reel unit, and rotation of the handle is transmitted to the pinion gear. The 1 st intermediate gear is provided rotatably about a 1 st axis parallel to the spool axis. The 1 st intermediate gear is provided with a 1 st large-diameter gear and a 1 st small-diameter gear, wherein the 1 st large-diameter gear is meshed with the pinion; the diameter of the 1 st small-diameter gear is smaller than that of the 1 st large-diameter gear, and the 1 st small-diameter gear and the 1 st large-diameter gear rotate integrally. The 2 nd intermediate gear is provided rotatably about a 2 nd axis parallel to the 1 st axis. The 2 nd intermediate gear is provided with a 2 nd large-diameter gear and a 2 nd small-diameter gear, wherein the 2 nd large-diameter gear is meshed with the 1 st small-diameter gear; the diameter of the 2 nd small-diameter gear is smaller than that of the 2 nd large-diameter gear, and the 2 nd small-diameter gear and the 2 nd large-diameter gear rotate integrally. The reciprocating mechanism is provided with a driven gear and a worm shaft (worm shaft) and is used for reciprocating the spool shaft in the front-back direction, wherein the driven gear is meshed with the 2 nd small-diameter gear; the worm shaft and the driven gear rotate integrally.

In this spinning reel, the 1 st intermediate gear and the 2 nd intermediate gear meshing with the 1 st intermediate gear are each constituted by a step gear, and the rotation of the pinion is transmitted to the driven gear of the reciprocating mechanism via the 1 st intermediate gear and the 2 nd intermediate gear. That is, the rotation of the pinion gear is greatly decelerated by the 1 st intermediate gear and the 2 nd intermediate gear and transmitted to the driven gear. In addition, the 1 st intermediate gear and the 2 nd intermediate gear are prevented from being enlarged, so that the fishing line can be tightly wound on the spool through the reciprocating mechanism while the fishing line reel body is prevented from being enlarged.

The reel unit may have a housing portion, a rod mounting portion for mounting a fishing rod, and a leg portion connecting the housing portion and the rod mounting portion. One of the worm shaft and the 1 st shaft is disposed at a position closer to the leg portion than the spool shaft when viewed in the axial direction of the spool shaft. The other of the worm shaft and the 1 st shaft is disposed at a position farther from the leg than the spool shaft when viewed in the axial direction of the spool shaft. In this case, since the 1 st shaft and the worm shaft are disposed with the spool shaft interposed therebetween, the 1 st intermediate gear, the 2 nd intermediate gear, the worm shaft, and the like can be disposed in the reel unit so as to be concentrated on one side of the spool shaft when viewed in the axial direction of the spool shaft while suppressing an increase in size of the reel unit.

The worm shaft may be configured to be located closer to the leg portion than the spool shaft when viewed from the axial direction of the spool shaft. In this case, the 1 st intermediate gear, the 2 nd intermediate gear, the worm shaft, and the like can be arranged in the reel unit so as to be concentrated on the spool shaft when viewed from the axial direction of the spool shaft, while suppressing an increase in size of the reel unit.

The driven gear may be disposed at a position farther from the spool than the 2 nd large-diameter gear in the axial direction of the spool shaft. In this case, the reel unit can be downsized in the axial direction of the spool shaft.

The module of the 2 nd large diameter gear may be 0.3 or less. In this case, the fishing line can be wound more tightly around the spool by the reciprocating mechanism.

[ Effect of the invention ]

According to the present invention, it is possible to provide a spinning reel that can tightly wind a fishing line around a spool while suppressing an increase in size of a reel unit.

Detailed Description

In the following description, the front and rear means that the direction in which the fishing line is released during fishing is referred to as front and the opposite direction is referred to as rear. The left and right sides refer to the left and right sides when the spinning reel 100 is viewed from the rear. For example, in fig. 1, the left side of fig. 1 is "front", the right side is "rear", the front side of the paper surface is "left", and the back side of the paper surface is "right". As shown in fig. 2, the direction in which the spool shaft 3 extends is referred to as the axial direction.

The spinning reel 100 according to an embodiment of the present invention includes a reel unit 2, a spool shaft 3, a spool 4, a rotor 5, a handle 6, a traverse mechanism 7, and a speed reduction mechanism 8.

The reel unit 2 includes a housing portion 2a, a rod mounting portion 2b, and a leg portion 2 c. One side (here, the left side) of the case portion 2a is open. As shown in fig. 2, inside the housing portion 2a, there are provided a reciprocating mechanism 7, a speed reduction mechanism 8, a rotor driving mechanism 12 (see fig. 3) that drives the rotor 5, and the like.

The fishing rod attachment portion 2b is a portion for attaching a fishing rod. The fishing rod attachment portion 2b is provided at an upper portion of the reel unit 2 and extends in the front-rear direction. The leg portion 2c extends in the vertical direction and connects the housing portion 2a and the rod attachment portion 2 b.

The reel unit 2 includes a cover member 2d that covers the opening of the housing portion 2a, and a cover member 2e that covers the rear of the housing portion 2 a.

The spool shaft 3 extends in the front-rear direction. The spool shaft 3 is supported by the reel unit 2 so as to be movable in the front-rear direction.

The reel 4 is a member for winding a fishing line around the outer periphery thereof. The spool 4 is supported by the spool shaft 3. More specifically, the spool 4 is fixed to the spool shaft 3 by a not-shown knob member screwed to the tip end of the spool shaft 3. The spool 4 reciprocates in the axial direction integrally with the spool shaft 3 in accordance with the rotation of the handle 6.

The rotor 5 is a member for winding a fishing line around the reel 4. The rotor 5 is rotatable about the axis of the spool shaft 3, and winds fishing line around the spool 4 in response to rotation of the handle 6 in the winding direction.

The handle 6 is rotatably supported by the reel unit 2. The handle 6 is provided on the left side of the reel unit 2 in the present embodiment.

Fig. 3 is a view of the inside of the reel unit 2 viewed from the right side with the housing portion 2a of the reel unit 2 omitted. As shown in fig. 3, the rotor drive mechanism 12 has a drive shaft 14, a drive gear 16, and a pinion gear 18. The drive shaft 14 is a cylindrical shaft and is rotatably supported by the reel unit 2 via a bearing, not shown. The drive shaft 14 extends in the left-right direction, and is connected to the handle 6 so as to be integrally rotatable.

The drive gear 16 is connected to the drive shaft 14 and rotates integrally with the drive shaft 14. In detail, the drive shaft 14 and the drive gear 16 are formed of a single member. The drive gear 16 is a face gear and meshes with the pinion gear 18. The pinion gear 18 is a cylindrical shaft and is disposed around the axis of the bobbin shaft 3. The pinion gear 18 is connected to the rotor 5 so as to be rotatable integrally therewith. The pinion gear 18 is rotatably supported by the reel unit 2 via a plurality of bearings disposed on the reel unit 2. As the handle 6 rotates, the drive shaft 14 and the drive gear 16 rotate, rotating the pinion gear 18 meshed with the drive gear 16, thereby transmitting the rotation of the handle 6 to the rotor 5.

The traverse mechanism 7 reciprocates the spool 4 in the axial direction in response to rotation of the handle 6. As shown in fig. 2, the reciprocating mechanism 7 has a worm shaft 21, a slider 22, guide shafts 23, 24, and a driven gear 25.

The worm shaft 21 is rotatably supported by the reel unit 2 via a bearing disposed on the reel unit 2. The worm shaft 21 is disposed above the drive shaft 14 in parallel with the spool shaft 3. Fig. 4 is a view of a part of the reel unit 2 viewed from the front. As shown in fig. 4, the worm shaft 21 is disposed closer to the leg portion 2c than the spool shaft 3 when viewed from the axial direction. As shown in fig. 3, a spiral groove is formed on the outer peripheral surface of the worm shaft 21. In fig. 2, the spiral groove of the worm shaft 21 is not shown.

The slider 22 extends vertically with the drive shaft 14 interposed therebetween, and is formed in a substantially U shape so as to extend along the outer peripheral portion of the drive shaft 14. The slider 22 is fixed to the rear end of the spool shaft 3. The slider 22 has an engagement pin, not shown, that engages with the spiral groove of the worm shaft 21.

The guide shafts 23, 24 guide the slider 22 to reciprocate in the axial direction. The guide shaft 23 is supported by the reel unit 2 at a position above the worm shaft 21 and is arranged parallel to the spool shaft 3. The guide shaft 24 is supported by the reel unit 2 below the drive shaft 14 and is arranged parallel to the spool shaft 3. Further, the slider 22 may be configured to be guided to move in the axial direction by 1 guide shaft. For example, the guide shaft 24 may be omitted.

The driven gear 25 is connected to the worm shaft 21 so as to be integrally rotatable. In the present embodiment, the driven gear 25 is a spur gear. The rotation of the handle 6 is transmitted to the driven gear 25 via the reduction mechanism 8. When the rotation of the handle 6 is transmitted to the driven gear 25, the worm shaft 21 rotates. Then, as the worm shaft 21 rotates, the engagement pin of the slider 22 is guided by the spiral groove of the worm shaft 21, and the spool shaft 3 reciprocates in the axial direction together with the slider 22.

The reduction mechanism 8 reduces the rotation of the handle 6 and transmits the rotation to the driven gear 25. Specifically, the reduction mechanism 8 reduces the rotation of the pinion gear 18 and transmits the rotation to the driven gear 25. The reduction mechanism 8 preferably reduces the speed so that the reduction ratio between the pinion gear 18 and the driven gear 25 is about 6. The reduction mechanism 8 has a 1 st intermediate gear 31 and a 2 nd intermediate gear 32.

The 1 st intermediate gear 31 is provided rotatably about a 1 st shaft 33 parallel to the spool shaft 3. The 1 st shaft 33 is supported by the reel unit 2. The 1 st shaft 33 is arranged to be located farther from the leg portion 2c than the spool shaft 3 when viewed from the axial direction. That is, the 1 st shaft 33 is disposed below the spool shaft 3 when viewed from the axial direction. The 1 st shaft 33 and the worm shaft 21 are disposed in the vertical direction with the spool shaft 3 interposed therebetween. The 1 st intermediate gear 31 is restricted from moving in the axial direction by a mechanism support portion 2f provided inside the housing portion 2a of the reel unit 2. The 1 st intermediate gear 31 has a 1 st large-diameter gear 31a and a 1 st small-diameter gear 31 b. The 1 st large diameter gear 31a is a helical gear and meshes with the pinion gear 18. The 1 st large-diameter gear 31a has a smaller diameter than the driven gear 25.

The 1 st small-diameter gear 31b is a spur gear. The 1 st small-diameter gear 31b has a smaller diameter than the 1 st large-diameter gear 31a, and rotates integrally with the 1 st large-diameter gear 31a about the 1 st shaft 33. The 1 st small-diameter gear 31b is disposed in front of the 1 st large-diameter gear 31 a. In the present embodiment, the 1 st large-diameter gear 31a and the 1 st small-diameter gear 31b are formed separately. Specifically, the 1 st small-diameter gear 31b has an engagement portion at the rear end thereof, which engages with a non-circular hole formed in the inner peripheral surface of the 1 st large-diameter gear 31a, and is connected to the 1 st large-diameter gear 31a so as to be integrally rotatable. The 1 st small-diameter gear 31b may be formed integrally with the 1 st large-diameter gear 31 a.

The 2 nd intermediate gear 32 is provided rotatably about a 2 nd shaft 34 parallel to the 1 st shaft 33. The 2 nd axis 34 is disposed parallel to the spool shaft 3. The 2 nd shaft 34 is disposed above the spool shaft 3 when viewed from the axial direction. The 2 nd shaft 34 is supported by the reel unit 2. The 2 nd intermediate gear 32 is restricted from moving in the axial direction by the mechanism supporting portion 2 f. The 2 nd intermediate gear 32 has a 2 nd large-diameter gear 32a and a 2 nd small-diameter gear 32 b. The 2 nd large-diameter gear 32a and the 2 nd small-diameter gear 32b are spur gears. The 2 nd large diameter gear 32a meshes with the 1 st small diameter gear 31 b. The 2 nd large diameter gear 32a has a diameter larger than that of the 1 st large diameter gear 31a and smaller than that of the driven gear 25. The 2 nd large diameter gear 32a is disposed forward of the driven gear 25. That is, the driven gear 25 is disposed at a position farther from the spool 4 than the 2 nd large-diameter gear 32 in the axial direction. The 2 nd large diameter gear 32a overlaps with the driven gear 25 and the 1 st large diameter gear 31a when viewed from the axial direction. The module of the 2 nd large diameter gear 32a is preferably 0.3 or less.

The 2 nd small-diameter gear 32b has a smaller diameter than the 2 nd large-diameter gear 32a, and rotates integrally with the 2 nd large-diameter gear 32 a. The 2 nd small-diameter gear 32b is disposed rearward of the 2 nd large-diameter gear 32 a. The 2 nd small-diameter gear 32b meshes with the driven gear 25. In the present embodiment, the 2 nd large-diameter gear 32a and the 2 nd small-diameter gear 32b are separately configured. Specifically, the 2 nd small-diameter gear 32b has an engagement portion at the tip thereof, which engages with a non-circular hole formed in the inner peripheral surface of the 2 nd large-diameter gear 32a, and is connected to the 2 nd large-diameter gear 32a so as to be integrally rotatable. The 2 nd small-diameter gear 32b may be formed integrally with the 2 nd large-diameter gear 32 a.

In the spinning reel 100 having the above-described configuration, the rotation of the pinion gear 18 is decelerated and transmitted to the driven gear 25 by the 1 st intermediate gear 31 and the 2 nd intermediate gear 32 of the speed reduction mechanism 8. This can significantly reduce the moving speed of the reciprocating mechanism 7 in the axial direction. Further, as compared with the case where the speed reduction mechanism 8 has only 1 intermediate gear, for example, the size increase of the speed reduction mechanism 8 can be suppressed. That is, by suppressing the size increase of the 1 st intermediate gear 31 and the 2 nd intermediate gear 32, the fishing line can be tightly wound around the spool 4 by the reciprocating mechanism 7 while suppressing the size increase of the reel unit 2.

< other embodiments >

While one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention. For example, the handle 6 may be disposed on the right side of the reel unit 2.

In the above embodiment, the driven gear 25 and the 2 nd small diameter gear 32b meshing with the driven gear 25 are spur gears, but the driven gear 25 and the 2 nd small diameter gear 32b may be constituted by helical gears.

In the above embodiment, the worm shaft 21 is disposed at a position closer to the leg portion 2c than the spool shaft 3 and the 1 st shaft 33 is disposed at a position farther from the leg portion 2c than the spool shaft 3 when viewed from the axial direction, but these arrangements may be changed. For example, as schematically shown in fig. 5, the worm shaft 21 may be disposed at a position farther from the leg portion 2c than the spool shaft 3 and the 1 st shaft 33 may be disposed at a position closer to the leg portion 2c than the spool shaft 3 when viewed from the axial direction.
