[0006] [Technical Problem to be Solved by the Invention]

[0007] For example, in the case where the reduction mechanism does not have a worm gear meshing with the driven gear, if the gears of the reduction mechanism are enlarged in order to obtain a desired gear ratio, the main body of the fishing reel will be enlarged.

[0008] The technical problem of the present invention is to provide a spinning reel capable of tightly winding a fishing line around a spool while suppressing the enlargement of the main body of the fishing reel.

[0009] [Technical Solution for Solving the Technical Problem]

[0010] One technical solution of the present invention relates to a spinning fishing reel, which has a fishing reel main body, a spool shaft, a spool, a handle, a pinion gear, a first intermediate gear, a second intermediate gear, and a reciprocating mechanism. The spool shaft is supported by the fishing reel main body in a manner that enables it to move back and forth in the front-rear direction. The spool is connected to the spool shaft, and fishing line is wound around its outer circumference. The handle is supported by the fishing reel main body in a rotatable manner. The pinion gear is supported by the fishing reel main body in a rotatable manner, and the rotation of the handle is transmitted to this pinion gear. The first intermediate gear is arranged to be rotatable about a first axis parallel to the spool shaft. The first intermediate gear has a first large-diameter gear and a first small-diameter gear, wherein the first large-diameter gear meshes with the pinion gear; the diameter of the first small-diameter gear is smaller than that of the first large-diameter gear, and the first small-diameter gear rotates integrally with the first large-diameter gear. The second intermediate gear is arranged to be rotatable about a second axis parallel to the first axis. The second intermediate gear has a second large-diameter gear and a second small-diameter gear, wherein the second large-diameter gear meshes with the first small-diameter gear; the diameter of the second small-diameter gear is smaller than that of the second large-diameter gear, and the second small-diameter gear rotates integrally with the second large-diameter gear. The reciprocating mechanism has a driven gear and a wormshaft for reciprocating the spool shaft back and forth in the front-rear direction, wherein the driven gear meshes with the second small-diameter gear; the wormshaft rotates integrally with the driven gear.

[0011] In this spinning fishing reel, the first intermediate gear and the second intermediate gear meshing with the first intermediate gear are each composed of a stepped gear, and the rotation of the pinion gear is transmitted to the driven gear of the reciprocating mechanism via the first intermediate gear and the second intermediate gear. That is, the rotation of the pinion gear is greatly decelerated by the first intermediate gear and the second intermediate gear and transmitted to the driven gear. Moreover, the enlargement of the first intermediate gear and the second intermediate gear is suppressed, whereby it is possible to suppress the enlargement of the fishing reel main body while tightly winding the fishing line around the spool by the reciprocating mechanism.

[0012] The fishing reel main body may have a housing portion, a fishing rod mounting portion for mounting a fishing rod, and a leg portion connecting the housing portion and the fishing rod mounting portion. One of the wormshaft and the first axis is arranged to be closer to the leg portion than the spool shaft when viewed from the axial direction of the spool shaft. The other of the wormshaft and the first axis is arranged to be farther from the leg portion than the spool shaft when viewed from the axial direction of the spool shaft. In this case, since the first axis and the wormshaft are arranged with the spool shaft therebetween, it is possible to suppress the enlargement of the fishing reel main body while centrally arranging the first intermediate gear, the second intermediate gear, the wormshaft, etc. on one side of the spool shaft when viewed from the axial direction of the spool shaft inside the fishing reel main body.

[0013] The worm shaft can be configured to be positioned closer to the leg than the spool shaft when viewed axially from the spool shaft. In this case, it is also possible to centrally arrange the first intermediate gear, the second intermediate gear, the worm shaft, etc. inside the fishing reel main body on one side of the spool shaft when viewed axially from the spool shaft while suppressing the enlargement of the fishing reel main body.

[0014] The driven gear can be configured to be positioned farther from the spool than the second large-diameter gear in the axial direction of the spool shaft. In this case, it is possible to miniaturize the fishing reel main body in the axial direction of the spool shaft.

[0015] The module of the second large-diameter gear can be 0.3 or less. In this case, it is possible to wind the fishing line more tightly around the spool by the reciprocating mechanism.

[0016] [Advantages of the Invention]

[0017] According to the present invention, it is possible to provide a spinning fishing reel that can wind the fishing line tightly around the spool while suppressing the enlargement of the fishing reel main body. Description of the Drawings

Detailed Description of the Invention

[0025] In the following description, front and back refer to the direction in which the fishing line is released during fishing and the opposite direction is called rear. In addition, left and right refer to the left and right when the spinning reel 100 is viewed from the rear. For example, Figure 1 middle, Figure 1 The left side of the paper is the "front", the right side is the "back", the front side of the paper is the "left", and the back side of the paper is the "right". Figure 2 As shown in the figure, the direction in which the spool shaft 3 extends is referred to as an axial direction.

[0026] A spinning reel 100 according to an embodiment of the present invention includes a reel body 2 , a spool shaft 3 , a spool 4 , a rotor 5 , a handle 6 , a reciprocating mechanism 7 , and a speed reduction mechanism 8 .

[0027] The fishing reel body 2 includes a housing 2a, a fishing rod mounting portion 2b, and a leg 2c. One side (here, the left side) of the housing 2a is open. Figure 2 As shown, inside the housing 2a, there are provided a reciprocating mechanism 7, a speed reduction mechanism 8, a rotor driving mechanism 12 for driving the rotor 5 (see Figure 3 )wait.

[0028] The fishing rod mounting portion 2b is used to mount a fishing rod. It is located on the upper portion of the reel body 2 and extends in the front-to-back direction. The leg portion 2c extends in the vertical direction and connects the housing 2a and the fishing rod mounting portion 2b.

[0029] The reel body 2 includes a lid member 2d that covers the opening of the case portion 2a, and a cover member 2e that covers the rear of the case portion 2a.

[0030] The spool shaft 3 extends in the front-rear direction and is supported by the reel body 2 so as to be movable in the front-rear direction.

[0031] The spool 4 is a member around which the fishing line is wound. The spool 4 is supported by the spool shaft 3. Specifically, the spool 4 is secured to the spool shaft 3 via a knob (not shown) that is screwed onto the top end of the spool shaft 3. The spool 4 reciprocates axially integrally with the spool shaft 3 as the handle 6 is rotated.

[0032] The rotor 5 is a member for winding the fishing line onto the spool 4. The rotor 5 is rotatable about the axis of the spool shaft 3 and winds the fishing line onto the spool 4 in response to rotation of the handle 6 in the winding direction.

[0033] The handle 6 is rotatably supported by the reel body 2. The handle 6 is provided on the left side of the reel body 2 in this embodiment.

[0034] Figure 3This is a view of the interior of the fishing reel main body 2 as seen from the right side with the housing portion 2a of the fishing reel main body 2 omitted. As Figure 3 shown, the rotor drive mechanism 12 has a drive shaft 14, a drive gear 16, and a pinion 18. The drive shaft 14 is a cylindrical shaft and is rotatably supported by the fishing reel main body 2 via bearings (not shown). The drive shaft 14 extends in the left - right direction and is connected to the handle 6 so as to be rotatable integrally.

[0035] The drive gear 16 is connected to the drive shaft 14 and rotates integrally with the drive shaft 14. Specifically, the drive shaft 14 and the drive gear 16 are formed of a single component. The drive gear 16 is a face gear and meshes with the pinion 18. The pinion 18 is a cylindrical shaft and is arranged around the axis of the spool shaft 3. The pinion 18 is connected to the rotor 5 so as to be rotatable integrally. The pinion 18 is rotatably supported by the fishing reel main body 2 via a plurality of bearings arranged on the fishing reel main body 2. As the handle 6 rotates, the drive shaft 14 and the drive gear 16 rotate, causing the pinion 18 meshing with the drive gear 16 to rotate, thereby transmitting the rotation of the handle 6 to the rotor 5.

[0036] The reciprocating mechanism 7 causes the spool 4 to reciprocate axially in response to the rotation of the handle 6. As Figure 2 shown, the reciprocating mechanism 7 has a worm shaft 21, a slider 22, guide shafts 23, 24, and a driven gear 25.

[0037] The worm shaft 21 is rotatably supported by the fishing reel main body 2 via bearings arranged on the fishing reel main body 2. In addition, the worm shaft 21 is arranged parallel to the spool shaft 3 at a position above the drive shaft 14. Figure 4 This is a view of a part of the fishing reel main body 2 as seen from the front. As Figure 4 shown, when viewed axially, the worm shaft 21 is arranged at a position closer to the leg portion 2c than the spool shaft 3. As Figure 3 shown, a helical groove is formed on the outer peripheral surface of the worm shaft 21. In addition, in Figure 2 the illustration of the helical groove of the worm shaft 21 is omitted.

[0038] The slider 22 extends vertically while clamping the drive shaft 14 and is formed in a substantially U - shaped manner 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 helical groove of the worm shaft 21.

[0039] The guide shafts 23 and 24 guide the slider 22 to reciprocate axially. The guide shaft 23 is supported by the fishing reel main body 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 fishing reel main body 2 at a position below the drive shaft 14 and is arranged parallel to the spool shaft 3. In addition, it can also be configured to guide the slider 22 to move axially through one guide shaft. For example, the guide shaft 24 can be omitted.

[0040] 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 helical groove of the worm shaft 21, so that the spool shaft 3 and the slider 22 move axially back and forth together.

[0041] The reduction mechanism 8 decelerates the rotation of the handle 6 and transmits it to the driven gear 25. Specifically, the reduction mechanism 8 decelerates the rotation of the pinion 18 and transmits it to the driven gear 25. Preferably, the reduction mechanism 8 decelerates in such a way that the reduction ratio between the pinion 18 and the driven gear 25 is about 6. The reduction mechanism 8 has a first intermediate gear 31 and a second intermediate gear 32.

[0042] The first intermediate gear 31 is arranged so as to be rotatable about a first shaft 33 parallel to the spool shaft 3. The first shaft 33 is supported by the fishing reel main body 2. The first shaft 33 is arranged at a position farther from the leg 2c than the spool shaft 3 when viewed axially. That is, the first shaft 33 is arranged at a position below the spool shaft 3 when viewed axially. The first shaft 33 and the worm shaft 21 are arranged with the spool shaft 3 therebetween in the vertical direction. The first intermediate gear 31 is restricted from moving axially by the mechanism support portion 2f inside the housing portion 2a of the fishing reel main body 2. The first intermediate gear 31 has a first large-diameter gear 31a and a first small-diameter gear 31b. The first large-diameter gear 31a is a helical gear and meshes with the pinion 18. The diameter of the first large-diameter gear 31a is smaller than the diameter of the driven gear 25.

[0043] The first small-diameter gear 31b is a spur gear. The diameter of the first small-diameter gear 31b is smaller than that of the first large-diameter gear 31a, and it rotates integrally with the first large-diameter gear 31a around the first shaft 33. The first small-diameter gear 31b is disposed in front of the first large-diameter gear 31a. In the present embodiment, the first large-diameter gear 31a and the first small-diameter gear 31b are separately formed. Specifically, the first small-diameter gear 31b has an engaging portion at the rear end and is connected to the first large-diameter gear 31a in a manner capable of rotating integrally, wherein the engaging portion engages with a non-circular hole formed in the inner peripheral surface of the first large-diameter gear 31a. In addition, the first small-diameter gear 31b may be integrally formed with the first large-diameter gear 31a.

[0044] The second intermediate gear 32 is provided so as to be rotatable around a second shaft 34 parallel to the first shaft 33. The second shaft 34 is disposed in parallel with the spool shaft 3. The second shaft 34 is disposed at a position above the spool shaft 3 when viewed from the axial direction. The second shaft 34 is supported by the fishing reel main body 2. The second intermediate gear 32 is restricted from moving in the axial direction by the mechanism support portion 2f. The second intermediate gear 32 has a second large-diameter gear 32a and a second small-diameter gear 32b. The second large-diameter gear 32a and the second small-diameter gear 32b are spur gears. The second large-diameter gear 32a meshes with the first small-diameter gear 31b. The diameter of the second large-diameter gear 32a is larger than that of the first large-diameter gear 31a and smaller than that of the driven gear 25. The second large-diameter gear 32a is disposed at a position in front of the driven gear 25. That is, the driven gear 25 is disposed at a position axially farther from the spool 4 than the second large-diameter gear 32. The second large-diameter gear 32a overlaps with the driven gear 25 and the first large-diameter gear 31a when viewed from the axial direction. Preferably, the module of the second large-diameter gear 32a is 0.3 or less.

[0045] The diameter of the second small-diameter gear 32b is smaller than that of the second large-diameter gear 32a, and it rotates integrally with the second large-diameter gear 32a. The second small-diameter gear 32b is disposed behind the second large-diameter gear 32a. The second small-diameter gear 32b meshes with the driven gear 25. In the present embodiment, the second large-diameter gear 32a and the second small-diameter gear 32b are separately formed. Specifically, the second small-diameter gear 32b has an engaging portion at the front end and is connected to the second large-diameter gear 32a in a manner capable of rotating integrally, wherein the engaging portion engages with a non-circular hole formed in the inner peripheral surface of the second large-diameter gear 32a. In addition, the second small-diameter gear 32b may be integrally formed with the second large-diameter gear 32a.

[0046] In the spinning fishing reel 100 having the above-described structure, the rotation of the pinion gear 18 is decelerated and transmitted to the driven gear 25 through the first intermediate gear 31 and the second intermediate gear 32 of the speed reduction mechanism 8. Accordingly, the axial movement speed of the reciprocating movement mechanism 7 can be significantly decreased. Also, compared with a case where the speed reduction mechanism 8 has, for example, only one intermediate gear, the enlargement of the speed reduction mechanism 8 can be suppressed. That is, by suppressing the enlargement of the first intermediate gear 31 and the second intermediate gear 32, accordingly, while suppressing the enlargement of the fishing reel main body 2, the fishing line can be tightly wound around the spool 4 by the reciprocating movement mechanism 7.

[0047] <Other Embodiments>

[0048] As described above, one embodiment of the present invention has been described, but the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the gist of the invention. For example, the handle 6 may also be disposed on the right side portion of the fishing reel main body 2.

[0049] In the above-described embodiment, the driven gear 25 and the second small-diameter gear 32b meshing with the driven gear 25 are spur gears, but the driven gear 25 and the second small-diameter gear 32b may be formed of helical gears.

[0050] In the above-described embodiment, when viewed from the axial direction, the worm shaft 21 is disposed closer to the leg portion 2c than the spool shaft 3, and the first shaft 33 is disposed farther from the leg portion 2c than the spool shaft 3, but these arrangements may be changed. For example, as Figure 5 schematically shown, when viewed from the axial direction, the worm shaft 21 may be disposed farther from the leg portion 2c than the spool shaft 3, and the first shaft 33 may be disposed closer to the leg portion 2c than the spool shaft 3.
