AI Technical Summary
In existing spinning reels, the meshing of sliding gears and cam gears is prone to instability, resulting in uneven movement of the drum shaft.
By introducing rotation limiting and sliding components into the spinning reel, the rotation direction of the second gear is limited, and friction is used to suppress meshing instability. For example, a one-way clutch or sliding component is used to generate friction by sliding against the reel body, thus ensuring stable gear meshing.
It effectively suppresses the meshing instability of sliding gears and cam gears, and improves the smoothness of the drum shaft movement and winding efficiency.

Abstract
Description
Technical Field
[0001] This invention relates to a spinning reel. Background Technology
[0002] Conventional spinning reels disclose a reciprocating mechanism (see Patent Document 1). This conventional reciprocating mechanism includes a sliding gear that rotates in conjunction with the rotation of a 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 protruding from the gear body. The boss engages with a groove in the slider. The boss moves along the groove, thereby moving the spool in the forward and backward direction via the spool shaft.
[0003] Patent document 1: Japanese Patent Application Publication No. 2004-065119.
[0004] In conventional reciprocating mechanisms, when the drum moves in the forward and backward direction via the drum shaft, the meshing of the sliding gear and cam gear may be unstable due to the force acting on the drum axially. Summary of the Invention
[0005] The present invention was made in view of the above-mentioned problems. The object of the present invention is to provide a spinning winding wheel capable of suppressing instability in the meshing of the sliding gear and the cam gear. Specifically, the object of the present invention is to provide a spinning winding wheel capable of suppressing instability in the meshing of the first gear and the second gear.
[0006] One embodiment of the present invention provides a spinning reel comprising 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 movable relative to the reel body in a forward-backward direction.
[0007] The reciprocating mechanism includes a first gear, a second gear, and a slider. The first gear rotates in a first rotational direction in conjunction with the 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 protruding from the gear body. The slider is mounted on a spool shaft and includes an engagement groove that engages with the first boss. A rotation limiting member is disposed between the winding reel body and the second gear. The rotation limiting member limits the rotation of the second gear in the first rotational direction.
[0008] In the spinning type winding wheel of the present invention, if the first gear rotates in the first rotation direction, the second gear rotates in the second rotation direction. At this time, the rotation limiting member restricts the rotation of the second gear in the first rotation direction, so it is possible to suppress the instability of the meshing of the first gear and the second gear.
[0009] In other embodiments of the spinning reel of the present invention, preferably, the rotation limiting member is 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, thus generating friction between the sliding member and the reel body. That is, the friction acts on the second gear via the sliding member. This suppresses instability in the meshing of the first and second gears.
[0010] In other embodiments of the spinning reel of the present invention, the reel body preferably has a second boss portion that rotatably supports the second gear. In this case, a 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 type winding wheel, the sliding member slides relative to the second boss portion of the winding wheel body, so the frictional force acts on the second gear through the sliding member. As a result, instability in the meshing of the first gear and the second gear can be suppressed.
[0012] In another embodiment of the spinning reel according to the invention, preferably, the second gear has a groove provided in the gear body. In this case, the sliding member has an engaging portion and a sliding portion, the engaging portion engaging with the groove, and the sliding portion integrally formed with the engaging portion, extending along the outer surface of the second boss portion and sliding against the outer surface of the second boss portion.
[0013] In this spinning type winding reel, the sliding member engages with the groove of the second gear, causing the sliding member and the second gear to rotate integrally. In this state, the sliding part of the sliding member slides against the outer surface of the second boss, so friction is applied to the second gear via the sliding member. This suppresses instability in the meshing of the first and second gears.
[0014] In another embodiment of the spinning winding wheel of the present invention, the sliding portion is formed in an arc shape. The sliding portion extends from the engaging portion along the outer surface of the second boss portion in the second rotational direction.
[0015] In this spinning reel, while the handle shaft and the first gear rotate in the first rotational direction to wind the fishing line, the second gear rotates in the second rotational direction. The arc-shaped sliding part extends along the outer surface of the second boss in the same direction as the second rotational direction of the second gear. Therefore, when winding the fishing line, the inner diameter of the arc-shaped sliding part increases, thus reducing the frictional force acting on the sliding part. As a result, the handle shaft can rotate smoothly when winding the line.
[0016] On the other hand, when the second gear is to rotate in the first rotational direction, the inner diameter of the arc-shaped sliding part is tensioned, thus increasing the frictional force acting on the sliding component. As a result, instability in the meshing of the first and second gears can be suppressed.
[0017] In other embodiments of the spinning winding reel of the present invention, preferably, the second boss portion has a boss body and a cylindrical component that is non-rotatably mounted on the outer periphery of the boss body. In this case, a sliding component is disposed between the second gear and the cylindrical component, and slides relative to the cylindrical component.
[0018] In this spinning type winding wheel, the cylindrical component is mounted to the outer periphery of the boss body in a non-rotatable manner. In this state, the sliding component slides relative to the cylindrical component. Even with this configuration, frictional force is applied to the second gear via the sliding component. As a result, instability in the meshing of the first and second gears can be suppressed. Furthermore, in this structure, the cylindrical component can be easily replaced if it wears out.
[0019] In other embodiments of the spinning reel 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 allows rotation of the second gear in the second rotational direction and limits rotation of the second gear in the first rotational direction.
[0020] In this spinning reel, when the handle shaft and the first gear rotate in the first rotational direction to wind the fishing line, the second gear rotates in the second rotational direction. Here, a one-way clutch allows the second gear to rotate in the second rotational direction, so the handle shaft can rotate smoothly when winding the line. On the other hand, the one-way clutch restricts the rotation of the second gear in the first rotational direction, so it can suppress instability in the meshing of the first and second gears.
[0021] Invention Effects
[0022] In this invention, the instability of the meshing of the first gear and the second gear can be suppressed in the spinning type winding wheel. Attached Figure Description

[0032] <First Embodiment>
[0033] The spinning type winding wheel 1 according to one embodiment of the present invention is as follows: Figure 1 As shown, it includes a winding reel body 3, a handle 5, a rotor 7, a drum 11, and a drive unit 13 (see reference). Figure 2 ), swing mechanism 30 (an example of a reciprocating mechanism; see reference) Figure 2 ), sliding component 40 (an example of a rotation limiting component; see reference) Figure 4 ).
[0034] like Figure 1 As shown, the handle 5 is rotatably supported on the winding reel body 3. In this embodiment, an example is shown where the handle 5 is positioned on the left side of the winding reel body 3. The handle 5 can also be positioned on the right side of the winding reel body 3. Figure 2 As shown, an oscillating mechanism 30 for moving the spool 11 in the front-back direction is arranged in the internal space of the winding wheel body 3.
[0035] Rotor 7 is used to wind fishing line onto spool 11. For example... Figure 1 and Figure 2 As shown, rotor 7 is positioned at the front of winding reel body 3. Rotor 7 is configured to rotate relative to winding reel body 3. For example, as... Figure 2 As shown, the rotor 7 is rotatably connected to the planetary gear 17. The planetary gear 17 is rotatably supported on the winding reel body 3. The rotor 7 and the planetary gear 17 rotate in conjunction.
[0036] The fishing line is wound onto the spool 11. The spool 11 is configured to move integrally with the spool shaft 9. For example, as Figure 2 As shown, the drum 11 is assembled at the end of the drum shaft 9.
[0037] The spool 9 is configured to move forward and backward relative to the winding reel body 3. The spool 9 is supported and movable relative to the winding reel body 3 in the front-back direction. The spool 9 is inserted into the inner circumference of the cylindrical planetary gear 17. The spool 9 reciprocates relative to the winding reel body 3 in the front-back direction via the operation of the oscillating mechanism 30. The front-back direction is the direction in which the spool axis X1 of the spool 9 extends.
[0038] like Figure 2 As shown, the drive unit 13 includes a drive shaft 21, a drive gear 23, and a sliding gear 31 (an example of the 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 mounted on the drive shaft 21.
[0039] 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 mounted to the inner circumference of the drive shaft 21. The handle shaft 6 is rotatably supported on the winding reel body 3. The axis of the handle shaft 6 is concentric with the drive axis X2.
[0040] A drive gear 23 is used to rotate the rotor 7. The drive gear 23 is located on the drive shaft 21. The drive gear 23 meshes with the planetary gear 17.
[0041] A sliding gear 31 is used to move the drum 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 disposed on the drive shaft 21 at a distance from the drive gear 23 in an axial direction extending from the drive shaft center X2. The drum shaft 9 and the guide shaft 34 (described later) are arranged between the drive gear 23 and the sliding gear 31. The sliding gear 31 meshes with the cam gear 33 (an example of the second gear) described later.
[0042] 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 can be formed separately. The drive shaft 21, drive gear 23, and sliding gear 31 rotate in conjunction with the rotation of the handle shaft 6. If the drive gear 23 and sliding gear 31 rotate, the planetary gear 17 and cam gear 33 rotate.
[0043] For example, in this embodiment, the rotation direction of the handle shaft 6, drive shaft 21, drive gear 23, and sliding gear 31 for winding the fishing line is defined as the first rotation direction R1. The rotation direction opposite to the first rotation direction R1 is defined as the second rotation direction R2. In addition, the first rotation direction R1 and the second rotation direction R2 are defined relative to the drive shaft X2 and shaft X3, respectively.
[0044] When the handle shaft 6, drive shaft 21, drive gear 23 and sliding gear 31 rotate in the first rotation direction R1 with the drive shaft center X2 as the reference, the cam gear 33 rotates in the second rotation direction R2 with the shaft center X3 as the reference.
[0045] The swing mechanism 30, in conjunction with the rotation of the handle shaft 6, causes the drum shaft 9 to move in the back-and-forth direction. For example... Figure 3 As shown, the swing mechanism 30 includes a sliding gear 31, a cam gear 33, a guide shaft 34, and a slider 35. Additionally, Figure 3 In the diagram, the teeth of the sliding gear 31 and the teeth of the cam gear 33 are simplified.
[0046] The sliding gear 31 constitutes the drive body 13 as described above. A cam gear 33 is used to move the slider 35 in the back-and-forth direction. The cam gear 33 is rotatably supported on the winding wheel body 3. For example, the cam gear 33 is rotatably supported on the boss portion 3b (an example of the second boss portion) of the winding wheel body 3. The cam gear 33 is disposed between the winding wheel body 3 and the slider 35.
[0047] Here, as Figure 2 and Figure 3 As shown, the boss portion 3b is included in the winding wheel body 3. That is, the winding wheel body 3 has a main body portion 3a, a boss portion 3b, and a side cover 3e (see reference). Figure 1 The main body 3a and the side cover 3e form a space for arranging the swing mechanism 30.
[0048] The boss portion 3b has a boss body 32 and a cylindrical component 41. The boss body 32 protrudes from the main body portion 3a. In detail, the boss body 32 protrudes from the side wall of the main body portion 3a in an axial direction extending from a shaft X3 parallel to the drive shaft X2.
[0049] like Figure 4 and Figure 5 As shown, the cylindrical member 41 is disposed between the cam gear 33 and the winding wheel body 3. The cylindrical member 41 is disposed on the outer periphery of the boss body 32 in a manner that prevents relative rotation. For example, the cylindrical member 41 is disposed radially away from the axis X3 between the outer peripheral surface of the boss body 32 and the inner peripheral surface of the step portion 38b (described later) of the cam gear 33. Furthermore, as... Figure 5 As shown, the cylindrical component 41 is disposed axially between the bottom surface of the stepped portion 38b of the cam gear 33 and the main body portion 3a, extending from the axis X3.
[0050] like Figure 4 and Figure 5 As shown, the cylindrical component 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. Figure 5As shown, the boss body 32 is disposed inside the cylindrical portion 41a.
[0051] The cylindrical portion 41a has a first end face 41a1 and a second end face 41a2. The first end face 41a1 is disposed facing the bottom surface of the stepped portion 38b. The second end face 41a2 is disposed facing the main body portion 3a.
[0052] like Figure 4 and Figure 5 As shown, an 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 about the axis X3. Figure 5 As shown, a sliding portion 40b of the sliding member 40 is disposed in the annular groove portion 41b (described later).
[0053] like Figure 4 and Figure 5 As shown, the protrusion 41c protrudes from the cylindrical portion 41a. For example, the protrusion 41c protrudes from the second end face 41a2 of the cylindrical portion 41a. Figure 5 As shown, the protrusion 41c fits into the recess 3c provided on the winding wheel body 3. For example, the recess 3c is provided on the side wall of the main body portion 3a of the winding wheel body 3. In this way, the protrusion 41c fits into the recess 3c, thereby configuring the cylindrical member 41 to be non-rotatable relative to the main body portion 3a when it is disposed on the outer periphery of the boss body 32.
[0054] like Figure 3 As shown, 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 rotatably supported on the winding wheel body 3 about an axis X3. The teeth of the gear body 38 mesh with the teeth of the sliding gear 31. For example, as... Figure 4 As shown, the gear body 38 has a hole 38a, a stepped portion 38b, and a groove 38c. The boss body 32 of the winding wheel body 3 is disposed in the hole 38a. The shaft X3 passes through the center of the hole 38a. The stepped portion 38b is formed in an annular shape. The aforementioned cylindrical member 41 is disposed in the stepped portion 38b.
[0055] like Figure 4 and Figure 5 As shown, the groove 38c is provided on the gear body 38 on the side opposite to the surface forming the boss 39. For example, the groove 38c extends outward from the inner circumferential surface of the stepped portion 38b in a radial direction away from the shaft X3. Figure 5 As shown, the engaging portion 40a (described later) of the sliding member 40 is disposed in the groove portion 38c.
[0056] like Figure 4 and Figure 5As shown, the boss 39 protrudes from the gear body 38. For example, the boss 39 protrudes from the gear body 38 in the axial direction extending from the drive shaft X2. The boss 39 engages with the engagement groove 37 of the slider 35, which will be described later.
[0057] like Figure 3 As shown, the boss portion 39, when disposed inside the engagement groove 37, 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 of the boss portion 39 being formed in a cylindrical shape is shown, but the boss portion 39 may also be formed in a frustum shape.
[0058] like Figure 2 and Figure 3 As shown, a guide shaft 34 is used to guide the slider 35 in the front-to-back direction. The guide shaft 34 is positioned above the spool 9. The guide shaft 34 is arranged parallel to the spool 9 (spool axis X1) and fixed to the winding reel body 3 (body part 3a).
[0059] like Figure 2 and Figure 3 As shown, a slider 35 is used to allow the spool 9 to move in the forward and backward direction. The slider 35 is mounted on the spool 9. For example, the slider 35 has a slider body 36 and a locking groove 37. The slider body 36 is fixed to the rear end of the spool 9. In addition, a guide shaft 34 is inserted into the slider body 36. The slider body 36 moves in the forward and backward direction along the guide shaft 34.
[0060] like Figure 3 As shown, the 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 assembled to the drum shaft 9 and the guide shaft 34, the engagement groove 37 extends upward from the drum shaft 9.
[0061] Viewing the engagement groove 37 from the handle 5 side along the axial direction extending from the drive shaft X2 ( Figure 3 In this case, the engaging groove 37 is formed in a curved shape. For example, in this case, the engaging groove 37 is formed in an S-shape. The boss portion 39 engages with the engaging groove 37.
[0062] Figure 4 and Figure 5 The sliding member 40 shown rotates integrally with the cam gear 33. The sliding member 40 restricts the rotation of the cam gear 33 in the first rotational direction R1. For example, the sliding member 40 slides with the winding wheel body 3. Specifically, the sliding member 40 slides relative to the cylindrical member 41 included in the winding wheel body 3.
[0063] like Figure 5As shown, the sliding member 40 is disposed axially between the cam gear 33 and the winding wheel body 3 (body part 3a) extending from the shaft X3. The sliding member 40 is disposed radially between the cam gear 33 and the cylindrical member 41 away from the shaft X3.
[0064] like Figure 4 and Figure 5 As shown, the sliding member 40 has an engaging portion 40a and a sliding portion 40b. The engaging portion 40a engages with the groove 38c of the cam gear 33. Figure 4 As shown, the sliding part 40b and the engaging part 40a are integrally formed. Figure 4 and Figure 5 As shown, the sliding part 40b extends along the outer surface of the cylindrical component 41.
[0065] For example, such as Figure 4 As shown, the sliding portion 40b extends from the engaging portion 40a along the outer surface of the cylindrical member 41 in the second rotational direction R2. The sliding portion 40b slides against the outer surface of the cylindrical member 41. More specifically, the sliding portion 40b is formed in an arc shape. The sliding portion 40b extends from the engaging portion 40a along the annular groove portion 41b in the second rotational direction R2. The sliding portion 40b slides against the annular groove portion 41b.
[0066] The aforementioned spinning type winding reel 1 has the following characteristics. In this spinning type winding reel 1, if the sliding gear 31 rotates along the first rotation direction R1, the cam gear 33 rotates along the second rotation direction R2. At this time, the sliding member 40 restricts the rotation of the cam gear 33 in the first rotation direction R1, so it is possible to suppress the instability of the meshing of the sliding gear 31 and the cam gear 33.
[0067] For example, if the cam gear 33 and the sliding gear 31 rotate in a first rotational direction R1 in conjunction, the sliding member 40 rotates integrally with the cam gear 33. At this time, the sliding member 40 slides against the winding wheel body, such as the cylindrical member 41, so friction is generated between the sliding member 40 and the winding wheel body 3. That is, this friction acts on the cam gear 33 via the sliding member 40.
[0068] This suppresses instability in the meshing of the sliding gear 31 and the cam gear 33. Furthermore, in this structure, the cylindrical member 41 is fitted into the main body portion 3a of the winding wheel body 3. Specifically, the protrusion 41c of the cylindrical member 41 fits into the recess 3c of the winding wheel body 3 (main body portion 3a). Therefore, the cylindrical member 41 can be easily replaced if it wears out.
[0069] In this spinning type winding reel 1, the engaging portion 40a of the sliding member 40 engages with the groove portion 38c of the cam gear 33, thereby causing the sliding member 40 and the cam gear 33 to rotate integrally. In this state, the sliding portion 40b of the sliding member 40 slides against the outer surface of the cylindrical member 41, so the aforementioned frictional force acts on the cam gear 33 via the sliding member 40. This allows for the appropriate suppression of instability in the meshing of the sliding gear 31 and the cam gear 33.
[0070] In this spinning reel 1, the arc-shaped sliding portion 40b extends along the outer surface of the cylindrical component 41 in the same direction as the second rotation direction R2 of the cam gear 33. Therefore, when winding the fishing line, the inner diameter of the arc-shaped sliding portion 40b increases, thus reducing the frictional force acting on the sliding component 40. As a result, the handle shaft 6 can rotate smoothly when winding the line.
[0071] On the other hand, when the cam gear 33 is to rotate in the first rotational direction R1, the arc-shaped sliding part 40b is tensioned, and the inner diameter of the arc-shaped sliding part 40b becomes smaller, so the frictional force acting on the sliding member 40 can be increased. As a result, the instability of the meshing of the sliding gear 31 and the cam gear 33 can be suppressed.
[0072] (Variation Example 1)
[0073] The foregoing embodiment illustrates an example where the cylindrical member 41 is assembled to the main body 3a. Alternatively, the cylindrical member 41 may be assembled to the boss body 32. In this case, the inner circumferential surface of the cylindrical portion 41a of the cylindrical member 41 is pressed into the outer circumferential surface of the boss body 32. Furthermore, in this case, Figure 4 and Figure 5 The protrusion 41c shown can also be omitted from the structure of the cylindrical component 41.
[0074] Even with this configuration, the frictional force generated by the sliding member 40 and the cylindrical member 41 acts on the cam gear 33 via the sliding member 40. Therefore, similar to the aforementioned embodiment, instability in the meshing of the sliding gear 31 and the cam gear 33 can be suppressed. Furthermore, if the cylindrical member 41 wears out, it can be easily replaced.
[0075] (Variation Example 2)
[0076] The foregoing embodiment illustrates an example where the engaging portion 40a of the sliding member 40 is disposed in the groove portion 38c of the cam gear 33. For example... Figure 6As shown, the groove portion 138c of the cam gear 33 may also 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 end portion of the engaging portion 40a of the sliding member 40 abuts against the second abutting portion 138c2.
[0077] In this structure, the engaging portion 40a of the sliding member 40 is held by the first abutting portion 138c1 and the second abutting portion 138c2. As a result, the frictional force generated by the sliding of the sliding member 40 and the cylindrical member 41 can be properly applied to the cam gear 33 via the sliding member 40.
[0078] (Variation Example 3)
[0079] The foregoing embodiments illustrate an example where the sliding member 40 slides against the cylindrical member 41. Instead, as... Figure 7 As shown, the cylindrical component 41 can also be omitted, and the sliding component 40 can slide with the boss body 32.
[0080] In this case, the sliding member 40 is disposed radially away from the axis X3 between the cam gear 33 and the boss portion 3b. The boss body 32 has an annular groove portion 3d. The annular groove portion 3d is formed on the outer peripheral surface of the boss body 32. For example, the annular groove portion 3d is formed on the outer peripheral surface of the boss body 32 in the circumferential direction about the axis X3.
[0081] The sliding member 40 has an engaging portion 40a and a sliding portion 40b, similar to those in the previous embodiment. The structures 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 rotational 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 3d of the boss body 32. In this state, the sliding portion 40b slides with the annular groove 3d of the boss body 32.
[0082] In this structure, the sliding member 40 slides relative to the boss body 32 of the reel body 3. Therefore, 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 suppresses instability in the meshing of the sliding gear 31 and the cam gear 33. Furthermore, when winding the fishing line, the inner diameter of the arc-shaped sliding part 40b increases, thus reducing the frictional force acting on the sliding member 40. This allows the handle shaft 6 to rotate smoothly when winding the line.
[0083] (Variation Example 4)
[0084] In the foregoing embodiments and variations 1 and 2, an example was shown in which an annular groove 41b was formed on the outer peripheral surface of the cylindrical member 41 to allow the sliding member 40 to slide on the outer peripheral surface of the cylindrical member 41. The shape of the portion of the sliding member 40 that slides on the outer peripheral surface of the cylindrical member 41 can be arbitrarily formed, as long as the sliding member 40 can slide on the outer peripheral surface of the cylindrical member 41. For example, an annular stepped portion may be formed on the outer peripheral surface of the cylindrical member 41 instead of the annular groove 41b.
[0085] <Second Implementation>
[0086] The spinning type winding reel 101 of the second embodiment is as follows: Figure 1 As shown, it includes a winding reel body 3, a handle 5, a rotor 7, a drum 11, and a drive unit 13 (see reference). Figure 2 ), swing mechanism 30 (an example of a reciprocating mechanism; see reference) Figure 2 ), one-way clutch 140 (an example of a rotation limiting component; see reference) Figure 8 ).
[0087] The structure of the spinning reel 101 is substantially the same as that of the first embodiment, except for the one-way clutch 140. Here, the description of the structure that is the same as that of the first embodiment is omitted.
[0088] like Figure 8 and Figure 9 As shown, the one-way clutch 140 is disposed between the cam gear 33 and the boss portion 3b (an example of the second boss portion). For example, the one-way clutch 140 is disposed between the gear body 38 and the boss body 32 in a radial direction away from the shaft X3.
[0089] Thus, 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 allows the cam gear 33 to rotate in the second rotational direction R2, while restricting the rotation of the cam gear 33 in the first rotational direction R1.
[0090] 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 a radial direction away from the shaft center X3.
[0091] Alternatively, the one-way clutch 140 may also have 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 a radial direction away from the shaft center X3.
[0092] The outer ring 140b is disposed radially away from the shaft X3 on the outer side of the rolling element 140a. The outer ring 140b is disposed on the stepped portion 38b of the gear body 38. For example, the outer ring 140b is non-rotatably fitted to the inner circumferential surface of the stepped portion 38b of the gear body 38. Specifically, the outer ring 140b is pressed into the inner circumferential surface of the stepped portion 38b of the gear body 38.
[0093] The aforementioned spinning type winding reel 1 has the following characteristics. For example, in this spinning type winding reel 1, if the sliding gear 31 rotates along the first rotation direction R1, then the cam gear 33 rotates along the second rotation direction R2. At this time, the one-way clutch 140 restricts the rotation of the cam gear 33 in the first rotation direction R1, so it is possible to suppress the instability of the meshing of the sliding gear 31 and the cam gear 33.
