Description

[Technical Field]

[0001] The present invention relates to a spinning reel. [Background technology]

[0002] A conventional spinning reel has a reciprocating mechanism (see Patent Document 1). The conventional reciprocating mechanism has a sliding gear that rotates in conjunction with the rotation of the handle shaft, a cam gear that meshes with the sliding gear, and a slider. The cam gear has a gear body that meshes with the sliding gear and a boss portion that protrudes from the gear body. The boss portion engages with an engagement groove in the slider. As the boss portion moves along the engagement groove, the spool moves back and forth via the spool shaft. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-065119 Summary of the Invention [Problem to be solved by the invention]

[0004] In a conventional reciprocating mechanism, when the spool moves back and forth via the spool shaft, the force acting on the spool in the axial direction of the spool can cause the meshing of the sliding gear and the cam gear to become unstable.

[0005] The present invention has been made in consideration of the above problems, and an object of the present invention is to provide a spinning reel that can prevent instability in the meshing between the sliding gear and the cam gear, i.e., a spinning reel that can prevent instability in the meshing between the first gear and the second gear. [Means for solving the problem]

[0006] A spinning reel according to one aspect of the present invention includes a reel body, a handle shaft, a spool shaft, a reciprocating mechanism, and a rotation limiting member. The handle shaft is rotatably supported relative to the reel body. The spool shaft is supported so as to be movable back and forth relative to the reel body.

[0007] The reciprocating mechanism has a first gear, a second gear, and a slider. The first gear rotates in a first rotational direction in conjunction with rotation of the handle shaft. The second gear rotates in a second rotational direction opposite to the first rotational direction. The second gear includes a gear body that meshes with the first gear and a first boss portion that protrudes from the gear body. The slider is attached to the spool shaft and includes an engagement groove that engages with the first boss portion. The rotation limiting member is disposed between the reel body and the second gear. The rotation limiting member limits rotation of the second gear in the first rotational direction.

[0008] In the spinning reel of the present invention, when the first gear rotates in a first rotational direction, the second gear rotates in a second rotational direction. At this time, the rotation limiting member limits the rotation of the second gear in the first rotational direction, thereby preventing instability in the meshing of the first gear and the second gear.

[0009] In a spinning reel according to another aspect of the present invention, the rotation-limiting member is preferably a sliding member that rotates integrally with the second gear and slides against the reel body. In this case, the sliding member slides against the reel body, generating friction between the sliding member and the reel body. That is, the friction acts on the second gear via the sliding member. This prevents instability in the meshing of the first gear and the second gear.

[0010] In a spinning reel according to another aspect of the present invention, the reel body preferably has a second boss portion that rotatably supports the second gear. In this case, the sliding member is disposed between the second gear and the second boss portion and slides relative to the second boss portion.

[0011] In this spinning reel, the sliding member slides against the second boss of the reel body, and frictional force acts on the second gear via the sliding member, which prevents instability in the meshing of the first gear and the second gear.

[0012] In a spinning reel according to another aspect of the present invention, the second gear preferably has a groove provided in the gear body. In this case, the sliding member has an engaging portion that engages with the groove, and a sliding portion that is formed integrally with the engaging portion, extends along the outer surface of the second boss, and slides against the outer surface of the second boss.

[0013] In this spinning reel, the engaging portion of the sliding member engages with the groove of the second gear, causing the sliding member to rotate integrally with the second gear. In this state, the sliding portion of the sliding member slides against the outer surface of the second boss, and frictional force acts on the second gear through the sliding member. This prevents instability in the meshing of the first gear and the second gear.

[0014] In a spinning reel according to another aspect of the present invention, the sliding portion is formed in an arc shape and extends from the engagement portion in the second rotation direction along the outer surface of the second boss portion.

[0015] In this spinning reel, when the handle shaft and first gear rotate in a first rotational direction to reel in the fishing line, the second gear rotates in a second rotational direction. The direction in which the arc-shaped sliding portion extends along the outer surface of the second boss portion is the same as the second rotational direction in which the second gear rotates. Therefore, when the fishing line is reeled in, the inner diameter of the arc-shaped sliding portion expands, thereby reducing the frictional force acting on the sliding member. This allows the handle shaft to rotate smoothly when reeling in the line.

[0016] On the other hand, when the second gear tries to rotate in the first rotation direction, the inner diameter of the arc-shaped sliding portion tightens, increasing the frictional force acting on the sliding member, thereby preventing instability in the meshing of the first gear and the second gear.

[0017] In a spinning reel according to another aspect of the present invention, the second boss portion preferably includes a boss body and a cylindrical member attached to the outer periphery of the boss body so as not to rotate relative to the boss body. In this case, the sliding member is disposed between the second gear and the cylindrical member and slides relative to the cylindrical member.

[0018] In this spinning reel, the tubular member is attached to the outer periphery of the boss body so as not to rotate relative to the boss body. In this state, the sliding member slides relative to the tubular member. Even with this configuration, frictional force acts on the second gear via the sliding member. This prevents instability in the meshing of the first gear and the second gear. Furthermore, with this configuration, the tubular member can be easily replaced if it becomes worn.

[0019] In a spinning reel according to another aspect of the present invention, the reel body preferably has a second boss portion that rotatably supports the second gear. In this case, the rotation limiting member is a one-way clutch disposed between the second gear and the second boss portion. The one-way clutch permits rotation of the second gear in the second rotational direction and restricts rotation of the second gear in the first rotational direction.

[0020] In this spinning reel, when the handle shaft and first gear rotate in a first rotational direction to reel in fishing line, the second gear rotates in a second rotational direction. Here, the one-way clutch allows the second gear to rotate in the second rotational direction, allowing the handle shaft to rotate smoothly when reeling in line. On the other hand, the one-way clutch restricts the rotation of the second gear in the first rotational direction, preventing instability in the meshing of the first gear and the second gear. [Effects of the Invention]

[0021] According to the present invention, it is possible to prevent instability in the meshing of the first gear and the second gear in a spinning reel. [Brief explanation of the drawings]

[0023] First Embodiment As shown in FIG. 1, a spinning reel 1 incorporating one embodiment of the present invention comprises a reel body 3, a handle 5, a rotor 7, a spool 11, a driver 13 (see FIG. 2), an oscillating mechanism 30 (an example of a reciprocating mechanism; see FIG. 2), and a sliding member 40 (an example of a rotation limiting member; see FIG. 4).

[0024] As shown in FIG. 1, the handle 5 is rotatably supported on the reel body 3. In this embodiment, an example is shown in which the handle 5 is located on the left side of the reel body 3. The handle 5 may also be located on the right side of the reel body 3. As shown in FIG. 2, an oscillating mechanism 30 for moving the spool 11 in the front-to-rear direction is located in the internal space of the reel body 3.

[0025] The rotor 7 is used to wind fishing line onto the spool 11. As shown in Figures 1 and 2, the rotor 7 is located at the front of the reel body 3. The rotor 7 is configured to be rotatable relative to the reel body 3. For example, as shown in Figure 2, the rotor 7 is connected to a pinion gear 17 so as to be rotatable together with the pinion gear 17. The pinion gear 17 is rotatably supported by the reel body 3. The rotor 7 rotates in conjunction with the rotation of the pinion gear 17.

[0026] Fishing line is wound around the spool 11. The spool 11 is configured to be movable integrally with the spool shaft 9. For example, as shown in FIG. 2, the spool 11 is attached to the tip of the spool shaft 9.

[0027] The spool shaft 9 is configured to be able to advance and retreat relative to the reel body 3. The spool shaft 9 is supported so that it can move in the front-to-rear direction relative to the reel body 3. The spool shaft 9 is inserted into the inner periphery of a cylindrical pinion gear 17. The spool shaft 9 moves back and forth in the front-to-rear direction relative to the reel body 3 by operation of the oscillating mechanism 30. The front-to-rear direction is the direction in which the spool axis center X1 of the spool shaft 9 extends.

[0028] 2, the driver 13 has a drive shaft 21, a drive gear 23, and a sliding gear 31 (an example of a first gear). The drive shaft 21 rotates in conjunction with the rotation of the handle 5. For example, the handle shaft 6 of the handle 5 is attached to the drive shaft 21.

[0029] The drive shaft 21 has a drive axis X2. For example, the drive shaft 21 is formed in a cylindrical shape. The handle shaft 6 is detachably attached to the inner periphery of the drive shaft 21. The handle shaft 6 is rotatably supported by the reel body 3. The axis of the handle shaft 6 is concentric with the drive axis X2.

[0030] The drive gear 23 is used to rotate the rotor 7. The drive gear 23 is provided on the drive shaft 21. The drive gear 23 meshes with the pinion gear 17.

[0031] The sliding gear 31 is used to move the spool shaft 9. The sliding gear 31 rotates in a first rotation direction R1 in conjunction with the rotation of the handle shaft 6. The sliding gear 31 is provided on the drive shaft 21 at a distance from the drive gear 23 in the axial direction in which the drive axis X2 extends. The spool shaft 9 and a guide shaft 34 (described later) are arranged between the drive gear 23 and the sliding gear 31. The sliding gear 31 meshes with a cam gear 33 (an example of a second gear) (described later).

[0032] The drive shaft 21, drive gear 23, and sliding gear 31 are integrally formed. Alternatively, the drive shaft 21, drive gear 23, and sliding gear 31 may be formed separately from one another. The drive shaft 21, drive gear 23, and sliding gear 31 rotate in conjunction with the rotation of the handle shaft 6. When the drive gear 23 and sliding gear 31 rotate, the pinion gear 17 and cam gear 33 rotate.

[0033] For example, in this embodiment, the direction in which the handle shaft 6, drive shaft 21, drive gear 23, and sliding gear 31 rotate to reel in the fishing line is defined as a first rotation direction R1. The direction of rotation opposite to the first rotation direction R1 is defined as a second rotation direction R2. The first rotation direction R1 and the second rotation direction R2 are defined relative to the drive axis X2 and axis X3, respectively.

[0034] When the handle shaft 6, drive shaft 21, drive gear 23, and sliding gear 31 rotate in a first rotation direction R1 about the drive axis X2, the cam gear 33 rotates in a second rotation direction R2 about the axis X3.

[0035] The oscillating mechanism 30 moves the spool shaft 9 back and forth in response to rotation of the handle shaft 6. As shown in Fig. 3, the oscillating mechanism 30 has a sliding gear 31, a cam gear 33, a guide shaft 34, and a slider 35. Note that in Fig. 3, the teeth of the sliding gear 31 and the teeth of the cam gear 33 are shown in a simplified manner.

[0036] As described above, the sliding gear 31 constitutes the driver 13. The cam gear 33 is used to move the slider 35 in the front-to-rear direction. The cam gear 33 is rotatably supported by the reel body 3. For example, the cam gear 33 is rotatably supported by the boss portion 3b (an example of a second boss portion) of the reel body 3. The cam gear 33 is disposed between the reel body 3 and the slider 35.

[0037] 2 and 3, the boss portion 3b is included in the reel body 3. That is, the reel body 3 has a main body 3a, a boss portion 3b, and a side cover 3e (see FIG. 1). The main body 3a and the side cover 3e form a space for disposing the oscillating mechanism 30.

[0038] The boss portion 3b has a boss main body 32 and a cylindrical member 41. The boss main body 32 protrudes from the main body portion 3a. Specifically, the boss main body 32 protrudes from the side wall of the main body portion 3a in the axial direction in which an axis X3 parallel to the drive axis X2 extends.

[0039] As shown in Figures 4 and 5, the cylindrical member 41 is disposed between the cam gear 33 and the reel body 3. The cylindrical member 41 is disposed on the outer periphery of the boss body 32 so as to be relatively non-rotatable. For example, the cylindrical member 41 is disposed between the outer periphery of the boss body 32 and the inner periphery of a stepped portion 38b (described later) of the cam gear 33 in the radial direction away from the axis X3. Furthermore, as shown in Figure 5, the cylindrical member 41 is disposed between the bottom surface of the stepped portion 38b of the cam gear 33 and the body portion 3a in the axial direction in which the axis X3 extends.

[0040] 4 and 5, the cylindrical member 41 has a cylindrical portion 41a, an annular groove portion 41b, and a protrusion 41c. The cylindrical portion 41a is formed in a cylindrical shape. As shown in Fig. 5, the boss main body 32 is disposed inside the cylindrical portion 41a.

[0041] The cylindrical portion 41a has a first end surface 41a1 and a second end surface 41a2. The first end surface 41a1 is disposed opposite to the bottom surface of the stepped portion 38b. The second end surface 41a2 is disposed opposite to the main body portion 3a.

[0042] 4 and 5, the annular groove 41b is formed on the outer peripheral surface of the cylindrical portion 41a. For example, the annular groove 41b is formed on the outer peripheral surface of the cylindrical portion 41a in the circumferential direction around the axis X3. As shown in Fig. 5, a sliding portion 40b (described later) of the sliding member 40 is disposed in the annular groove 41b.

[0043] As shown in FIGS. 4 and 5, the protrusion 41c protrudes from the tubular portion 41a. For example, the protrusion 41c protrudes from the second end surface 41a2 of the tubular portion 41a. As shown in FIG. 5, the protrusion 41c is fitted into a recess 3c provided in the reel body 3. For example, the recess 3c is provided in the side wall of the main body portion 3a of the reel body 3. By fitting the protrusion 41c into the recess 3c in this manner, the tubular member 41 is configured to be non-rotatable with respect to the main body portion 3a while being disposed on the outer periphery of the boss body 32.

[0044] As shown in FIG. 3, the cam gear 33 has a gear body 38 and a boss portion 39 (an example of a first boss portion). The gear body 38 is supported by the reel body 3 so as to be rotatable about the axis X3. The teeth of the gear body 38 mesh with the teeth of the sliding gear 31. For example, as shown in FIG. 4, the gear body 38 has a hole portion 38a, a step portion 38b, and a groove portion 38c. The boss body 32 of the reel body 3 is disposed in the hole portion 38a. The axis X3 passes through the center of the hole portion 38a. The step portion 38b is formed in an annular shape. The above-mentioned cylindrical member 41 is disposed in the step portion 38b.

[0045] 4 and 5, the groove 38c is provided on the surface of the gear body 38 opposite to the surface on which the boss 39 is formed. For example, the groove 38c extends outward from the inner circumferential surface of the stepped portion 38b in the radial direction away from the axis X3. As shown in Fig. 5, an engaging portion 40a (described later) of the sliding member 40 is disposed in the groove 38c.

[0046] 4 and 5, the boss portion 39 protrudes from the gear body 38. For example, the boss portion 39 protrudes from the gear body 38 in the axial direction in which the drive axis X2 extends. The boss portion 39 engages with an engagement groove 37 of the slider 35, which will be described later.

[0047] 3, the boss portion 39 is disposed inside the engagement groove 37 and moves along the engagement groove 37 in conjunction with the rotation of the gear body 38. The boss portion 39 is formed in a cylindrical shape. In this embodiment, an example in which the boss portion 39 is formed in a cylindrical shape is shown, but the boss portion 39 may also be formed in a truncated cone shape.

[0048] 2 and 3, the guide shaft 34 is used to guide the slider 35 in the front-to-rear direction. The guide shaft 34 is disposed above the spool shaft 9. The guide shaft 34 is disposed parallel to the spool shaft 9 (spool axis X1) and is fixed to the reel body 3 (main body portion 3a).

[0049] As shown in Figures 2 and 3, the slider 35 is used to move the spool shaft 9 in the front-rear direction. The slider 35 is attached to the spool shaft 9. For example, the slider 35 has a slider body 36 and an engagement groove 37. The slider body 36 is fixed to the rear end of the spool shaft 9. The guide shaft 34 is inserted into the slider body 36. The slider body 36 moves in the front-rear direction along the guide shaft 34.

[0050] 3, a boss portion 39 is disposed in the engagement groove 37. The engagement groove 37 is provided in the slider body 36. For example, when the slider body 36 is attached to the spool shaft 9 and the guide shaft 34, the engagement groove 37 extends upward from the spool shaft 9.

[0051] When the engagement groove 37 is viewed from the handle 5 side in the axial direction in which the drive axis X2 extends (as in FIG. 3), the engagement groove 37 is formed in a curved shape. For example, in this case, the engagement groove 37 is formed in an S-shape. A boss portion 39 engages with the engagement groove 37.

[0052] 4 and 5 rotates integrally with the cam gear 33. The sliding member 40 limits the rotation of the cam gear 33 in the first rotation direction R1. For example, the sliding member 40 slides against the reel body 3. Specifically, the sliding member 40 slides against a cylindrical member 41 included in the reel body 3.

[0053] 5, the sliding member 40 is disposed between the cam gear 33 and the reel body 3 (main body portion 3a) in the axial direction in which the axis X3 extends. The sliding member 40 is disposed between the cam gear 33 and the cylindrical member 41 in the radial direction away from the axis X3.

[0054] 4 and 5, the sliding member 40 has an engaging portion 40a and a sliding portion 40b. The engaging portion 40a engages with the groove portion 38c of the cam gear 33. As shown in FIG. 4, the sliding portion 40b is formed integrally with the engaging portion 40a. As shown in FIGS. 4 and 5, the sliding portion 40b extends along the outer surface of the cylindrical member 41.

[0055] For example, as shown in FIG. 4, the sliding portion 40b extends from the engaging portion 40a in the second rotation direction R2 along the outer surface of the cylindrical member 41. The sliding portion 40b slides on the outer surface of the cylindrical member 41. Specifically, the sliding portion 40b is formed in an arc shape. The sliding portion 40b extends from the engaging portion 40a in the second rotation direction R2 along the annular groove portion 41b. The sliding portion 40b slides on the annular groove portion 41b.

[0056] The above-described spinning reel 1 has the following features. In this spinning reel 1, when the sliding gear 31 rotates in the first rotational direction R1, the cam gear 33 rotates in the second rotational direction R2. At this time, the sliding member 40 limits the rotation of the cam gear 33 in the first rotational direction R1, thereby preventing instability in the meshing between the sliding gear 31 and the cam gear 33.

[0057] For example, when the cam gear 33 rotates in the first rotation direction R1 in conjunction with the rotation of the sliding gear 31, the sliding member 40 rotates integrally with the cam gear 33. At this time, the sliding member 40 slides against the reel body, for example, the cylindrical member 41, and a frictional force is generated between the sliding member 40 and the reel body 3. In other words, this frictional force acts on the cam gear 33 via the sliding member 40.

[0058] This prevents instability in the meshing between the sliding gear 31 and the cam gear 33. Furthermore, with this configuration, the cylindrical member 41 is attached to the main body 3a of the reel body 3. Specifically, the protruding portion 41c of the cylindrical member 41 fits into the recessed portion 3c of the reel body 3 (main body 3a). This allows the cylindrical member 41 to be easily replaced when it wears out.

[0059] In the present spinning reel 1, the engaging portion 40a of the sliding member 40 is engaged with the groove portion 38c of the cam gear 33, so that the sliding member 40 rotates integrally with the cam gear 33. In this state, the sliding portion 40b of the sliding member 40 slides against the outer surface of the cylindrical member 41, and the above-mentioned friction force acts on the cam gear 33 via the sliding member 40. This makes it possible to suitably prevent instability in the meshing between the sliding gear 31 and the cam gear 33.

[0060] In this spinning reel 1, the direction in which the arc-shaped sliding portion 40b extends along the outer surface of the tubular member 41 is the same as the second rotation direction R2 in which the cam gear 33 rotates. Therefore, when the fishing line is wound in, the inner diameter of the arc-shaped sliding portion 40b expands, thereby reducing the frictional force acting on the sliding member 40. This allows the handle shaft 6 to rotate smoothly when winding in the line.

[0061] On the other hand, when the cam gear 33 tries to rotate in the first rotation direction R1, the arc-shaped sliding portion 40b tightens and the inner diameter of the arc-shaped sliding portion 40b decreases, thereby increasing the frictional force acting on the sliding member 40. This makes it possible to prevent the meshing between the sliding gear 31 and the cam gear 33 from becoming unstable.

[0062] (Variation 1) In the above embodiment, an example has been shown in which the cylindrical member 41 is attached to the main body portion 3a. Alternatively, the cylindrical member 41 may be attached to the boss main body 32. In this case, the inner circumferential surface of the cylindrical portion 41a of the cylindrical member 41 is press-fitted into the outer circumferential surface of the boss main body 32. In this case, the protrusion 41c shown in FIGS. 4 and 5 may be omitted from the configuration of the cylindrical member 41.

[0063] Even with this configuration, the frictional force generated by the sliding of the sliding member 40 and the tubular member 41 acts on the cam gear 33 via the sliding member 40. This makes it possible to prevent instability in the meshing of the sliding gear 31 and the cam gear 33, as in the above embodiment. Furthermore, when the tubular member 41 wears out, it can be easily replaced.

[0064] (Variation 2) In the above embodiment, an example has been shown in which the engaging portion 40a of the sliding member 40 is disposed in the groove portion 38c of the cam gear 33. As shown in FIG. 6, the groove portion 138c of the cam gear 33 may have a first abutting portion 138c1 and a second abutting portion 138c2. In this case, the base end of the engaging portion 40a of the sliding member 40 abuts against the first abutting portion 138c1. The tip end of the engaging portion 40a of the sliding member 40 abuts against the second abutting portion 138c2.

[0065] In this configuration, the engaging portion 40a of the sliding member 40 is held by the first contact portion 138c1 and the second contact portion 138c2. This allows the frictional force generated by the sliding of the sliding member 40 and the cylindrical member 41 to be suitably applied to the cam gear 33 via the sliding member 40.

[0066] (Variation 3) In the above embodiment, an example has been shown in which the sliding member 40 slides on the cylindrical member 41. Alternatively, as shown in Fig. 7, the sliding member 40 may be configured to slide on the boss main body 32 without using the cylindrical member 41.

[0067] In this case, the sliding member 40 is disposed between the cam gear 33 and the boss portion 3b in the radial direction away from the axis X3. The boss body 32 has an annular groove 3d. The annular groove 3d is formed in the outer peripheral surface of the boss body 32. For example, the annular groove 3d is formed in the outer peripheral surface of the boss body 32 in the circumferential direction around the axis X3.

[0068] The sliding member 40 has an engaging portion 40a and a sliding portion 40b, as in the previous embodiment. The configurations of the engaging portion 40a and the sliding portion 40b are substantially the same as in the previous embodiment. The sliding portion 40b extends along the outer surface of the boss body 32. For example, the sliding portion 40b is formed in an arc shape. The sliding portion 40b extends from the engaging portion 40a along the outer surface of the boss body 32 in the second rotation direction R2. The sliding portion 40b is disposed on the outer surface of the boss body 32. For example, the sliding portion 40b is disposed in the annular groove portion 3d of the boss body 32. In this state, the sliding portion 40b slides in the annular groove portion 3d of the boss body 32.

[0069] In this configuration, the sliding member 40 slides against the boss body 32 of the reel body 3, and the frictional force generated by the sliding of the sliding member 40 and the boss body 32 acts on the cam gear 33 via the sliding member 40. This makes it possible to prevent instability in the meshing of the sliding gear 31 and the cam gear 33. Furthermore, when the fishing line is being reeled in, the inner diameter of the arc-shaped sliding portion 40b expands, thereby reducing the frictional force acting on the sliding member 40. This allows the handle shaft 6 to rotate smoothly when reeling in the line.

[0070] (Variation 4) In the above embodiment and the above modified examples 1 and 2, an example has been shown in which an annular groove portion 41b is formed on the outer peripheral surface of the cylindrical member 41 so that the sliding member 40 can slide on the outer peripheral surface of the cylindrical member 41. The shape of the portion where the sliding member 40 slides on the cylindrical member 41 may be formed in any way as long as the sliding member 40 can slide on the outer peripheral surface of the cylindrical member 41. For example, instead of the annular groove portion 41b, an annular step portion may be formed on the outer peripheral surface of the cylindrical member 41.

[0071] Second Embodiment As shown in FIG. 1, the spinning reel 101 in the second embodiment comprises a reel body 3, a handle 5, a rotor 7, a spool 11, a driver 13 (see FIG. 2), an oscillating mechanism 30 (an example of a reciprocating mechanism; see FIG. 2), and a one-way clutch 140 (an example of a rotation limiting member; see FIG. 8).

[0072] The configuration of the spinning reel 101 is substantially the same as that of the first embodiment, except for the one-way clutch 140. Here, a description of the configuration that is the same as that of the first embodiment will be omitted.

[0073] 8 and 9, the one-way clutch 140 is disposed between the cam gear 33 and the boss portion 3b (an example of a second boss portion). For example, the one-way clutch 140 is disposed between the gear body 38 and the boss body 32 in the radial direction away from the axis X3.

[0074] As a result, the boss body 32 of the boss portion 3b rotatably supports the gear body 38 of the cam gear 33 via the one-way clutch 140. In this state, the one-way clutch 140 permits rotation of the cam gear 33 in the second rotation direction R2 and restricts rotation of the cam gear 33 in the first rotation direction R1.

[0075] The one-way clutch 140 has a rolling element 140a and an outer ring 140b. The rolling element 140a is disposed on the outer peripheral surface of the boss body 32. For example, the rolling element 140a is disposed between the outer peripheral surface of the boss body 32 and the outer ring 140b in the radial direction away from the axis X3.

[0076] The one-way clutch 140 may further include an inner ring. In this case, the inner ring is disposed on the outer peripheral surface of the boss body 32. The rolling element 140a is disposed between the inner ring and the outer ring 140b in the radial direction away from the axis X3.

[0077] The outer ring 140b is disposed on the outer side of the rolling element 140a in the radial direction away from the axis X3. The outer ring 140b is disposed in the stepped portion 38b of the gear body 38. For example, the outer ring 140b is non-rotatably attached to the inner circumferential surface of the stepped portion 38b of the gear body 38. Specifically, the outer ring 140b is press-fitted into the inner circumferential surface of the stepped portion 38b of the gear body 38.

[0078] The above-described spinning reel 1 has the following characteristics. For example, in this spinning reel 1, when the sliding gear 31 rotates in the first rotational direction R1, the cam gear 33 rotates in the second rotational direction R2. At this time, the one-way clutch 140 limits the rotation of the cam gear 33 in the first rotational direction R1, thereby preventing instability in the meshing between the sliding gear 31 and the cam gear 33. [Industrial Applicability]
