[0002] A fishing reel, for example the dual-bearing reel disclosed in Patent Document 1, includes a reel body, a spool shaft, and a one-way clutch unit. The spool shaft is rotatably supported by the reel body.
[0003] The one-way clutch unit includes a rolling element and an outer member. The rolling element contacts the spool shaft in a radial direction. The outer member functions as an outer ring of the rolling element. The outer member is disposed outside the rolling element in the radial direction. The outer member rotates in only one direction in the circumferential direction. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Patent No. 6560903 Summary of the Invention [Problem to be solved by the invention]
[0005] In the conventional configuration, a friction plate comes into contact with the one-way clutch unit. More specifically, the friction plate comes into contact with an end face of an outer member of the one-way clutch unit. In this case, since the plate comes into contact with the end face of the outer member where friction is not anticipated, it is difficult to stably apply a braking force to the outer member.
[0006] An object of the present invention is to provide a one-way clutch unit for a fishing reel that can stably apply a braking force to an outer member. [Means for solving the problem]
[0007] A one-way clutch unit for a fishing reel according to one aspect of the present invention brakes the rotation of a shaft member of the fishing reel. The one-way clutch unit for a fishing reel includes a rolling element and an outer member. The rolling element contacts the shaft member in a radial direction away from the axis of the shaft member. The outer member is disposed radially outward of the rolling element. The outer member rotates only in one direction in the circumferential direction around the axis of the shaft member. The outer member is provided with a first external force receiving portion that receives a first external force in the axial direction in which the axis extends.
[0008] In the one-way clutch unit of the fishing reel of the present invention, the outer member receives the first external force in the axial direction at the first external force receiving portion, which allows a braking force to be stably applied to the outer member.
[0009] In a one-way clutch unit for a fishing reel according to another aspect of the present invention, the first external force receiving portion preferably has a first protruding portion protruding in the axial direction. In this configuration, the outer member receives the first external force in the axial direction at the first protruding portion. This allows a braking force to be stably applied to the outer member.
[0010] In a one-way clutch unit for a fishing reel according to another aspect of the present invention, the outer member preferably has a retaining portion and a holder. The retaining portion is disposed radially outward of the rolling elements and retains the rolling elements. The holder is provided on the retaining portion and rotates integrally with the retaining portion. The first protrusion is provided on the holder.
[0011] In this configuration, the outer member receives the first external force in the axial direction at the first protrusion of the holder, which allows a braking force to be applied stably to the outer member.
[0012] In a fishing reel one-way clutch unit according to another aspect of the present invention, the holder preferably has a first holder and a second holder. The first holder is provided on the holding part so as to cover an end of the shaft member. The second holder is provided on the holding part on the opposite side of the first holder in the axial direction.
[0013] In this configuration, the first holder and the second holder are provided on the holding portion. The outer member receives the first external force in the axial direction at the first holder. This makes it possible to stably apply a braking force to the outer member.
[0014] In the fishing reel one-way clutch unit according to another aspect of the present invention, the first holder and the second holder are preferably bonded or press-fitted into the holding portion. In this configuration, the first holder and the second holder can be suitably attached to the holding portion.
[0015] In a fishing reel one-way clutch unit according to another aspect of the present invention, the first holder and the second holder are preferably screwed together to clamp the holding part. In this configuration, the first holder and the second holder can be suitably attached to the holding part.
[0016] In a one-way clutch unit for a fishing reel according to another aspect of the present invention, it is preferable that the first external force receiving portion has an annular second protrusion protruding in the axial direction. In this configuration, the outer member receives the first external force in the axial direction at the annular second protrusion. This allows a braking force to be applied stably to the outer member.
[0017] In a fishing reel one-way clutch unit according to another aspect of the present invention, it is preferable that the outer member is further provided with a second external force receiving portion that receives a second external force acting in a direction opposite to the first external force.
[0018] In this configuration, the outer member can be braked by the first external force acting on the first external force receiving portion and the second external force acting on the second external force receiving portion, thereby making it possible to stably apply a braking force to the outer member.
[0019] A fishing reel according to one aspect of the present invention includes a reel body, a shaft member configured to be rotatable relative to the reel body, and the one-way clutch unit described above. In this case, the one-way clutch unit is provided on the reel body and brakes the rotation of the shaft member. By configuring the fishing reel in this manner, the same effects as those described above can be obtained. In a fishing reel according to another aspect of the present invention, it is preferable that the shaft member has a protrusion. The outer member has a retaining portion and a holder. The retaining portion is disposed outside the rolling elements in a radial direction away from the axis of the shaft member and retains the rolling elements. The holder is provided on the retaining portion and rotates integrally with the retaining portion. The holder has a first holder and a second holder. The first holder is provided on the holding part so as to cover the end of the shaft member. The second holder is provided on the holding part on the opposite side to the first holder in the axial direction in which the shaft center extends. The second holder has a recess that engages with the protrusion. In this configuration, the shaft part can be suitably positioned in the second holder by engaging the protrusion of the shaft part with the recess. Effect of the Invention
[0020] According to the present invention, in a one-way clutch unit of a fishing reel, braking force can be stably applied to the outer member. [Brief description of the drawings]

[0022] An embodiment of a dual-bearing reel 1 (one example of a fishing reel) according to the present invention will now be described with reference to the drawings. As shown in Fig. 1, dual-bearing reel 1 comprises a reel body 3, a spool 5, a handle 7, and an operating lever 9. As shown in Fig. 2, dual-bearing reel 1 further comprises a spool shaft 11 (one example of a shaft member), a connecting shaft 13 (one example of a shaft member), and a one-way clutch unit 14. Dual-bearing reel 1 further comprises a first seal member 19 and a second seal member 20.
[0023] The axial direction is the direction in which the first axis X1 of the spool shaft 11 extends. The radial direction is the direction perpendicular to and away from the first axis X1 of the spool shaft 11. The circumferential direction is the direction around the first axis X1 of the spool shaft 11.
[0024] As shown in FIG. 2, the reel body 3 has a frame 31, a first side cover 33, and a second side cover 35. The frame 31 has a first side plate 31a, a second side plate 31b, and a plurality of connecting portions 31c. The first side plate 31a and the second side plate 31b are arranged at intervals from each other in the axial direction. The first side plate 31a and the second side plate 31b are connected to each other via the plurality of connecting portions 31c. The first side plate 31a, the second side plate 31b, and the plurality of connecting portions 31c are integrally formed.
[0025] The first side cover 33 covers the first side plate 31a. For example, the first side cover 33 has a cover body 33a and a protruding portion 33b. The cover body 33a covers the first side plate 31a between the handle 7 and the first side plate 31a. The protruding portion 33b protrudes axially outward from the cover body 33a. The protruding portion 33b is formed in a cylindrical shape. The protruding portion 33b communicates from the internal space of the first side cover 33 and the first side plate 31a to the external space. The second side cover 35 covers the second side plate 31b. In detail, the second side cover 35 covers the second side cover 35 on the side opposite to the handle 7.
[0026] 2, the spool 5 is rotatably supported by the reel body 3. For example, the spool 5 is attached to the spool shaft 11 so as to rotate integrally with the spool shaft 11. In other words, the spool 5 is rotatably supported by the reel body 3 via the spool shaft 11.
[0027] The handle 7 shown in FIG. 1 is a member for rotating the spool shaft 11. The handle 7 is attached to the reel body 3. For example, the handle 7 is rotatably supported by the reel body 3 via a drive shaft 10a shown in FIG. 2. For example, when the handle 7 and the drive shaft 10a rotate, the spool shaft 11 and the spool 5 rotate via the rotation transmission mechanism 10.
[0028] 2, the rotation transmission mechanism 10 is disposed in the internal space between the first side cover 33 and the first side plate 31a. The rotation transmission mechanism 10 is a mechanism that transmits the rotation of the handle 7 to the spool shaft 11. The rotation transmission mechanism 10 has a drive shaft 10a, a drive gear 10b, and a pinion gear 10c.
[0029] The drive shaft 10a is rotatably supported by the first side plate 31a and the first side cover 33. The drive shaft 10a rotates integrally with the handle 7. The drive gear 10b rotates integrally with the drive shaft 10a.
[0030] The pinion gear 10c is rotatably supported by the first side plate 31a and the first side cover 33 via a plurality of bearings 61a, 61b. The pinion gear 10c meshes with the drive gear 10b. The pinion gear 10c is formed in a cylindrical shape. The spool shaft 11 is inserted into the inner periphery of the pinion gear 10c.
[0031] The pinion gear 10c is guided axially along the spool shaft 11 by the clutch yoke 12. Rotation from the pinion gear 10c to the spool shaft 11 is transmitted by engagement between an engagement pin 10d1 of the spool shaft 11 and an engagement recess 10d2 of the pinion gear 10c. When the engagement between the engagement pin 10d1 and the engagement recess 10d2 is released, the rotation of the pinion gear 10c is not transmitted to the spool shaft 11.
[0032] 1 and 2, the operating lever 9 is attached to the reel body 3. For example, as shown in Fig. 2, the operating lever 9 is attached to the protruding portion 33b of the first side cover 33. In detail, the operating lever 9 is attached so as to be able to swing relative to the protruding portion 33b.
[0033] The one-way clutch unit 14 is pressed in the axial direction by the pivoting of the operating lever 9. For example, the one-way clutch unit 14 is pressed in the axial direction between the first friction plate 18a and the second friction plate 18b by the pivoting of the operating lever 9.
[0034] The spool shaft 11 rotates integrally with the spool 5. The spool shaft 11 is configured to be rotatable relative to the reel body 3. As shown in Fig. 2, the spool shaft 11 is rotatably supported by the reel body 3. For example, the spool shaft 11 is rotatably supported by the reel body 3 via a plurality of bearings 71a, 71b.
[0035] 2, 3, and 4, the spool shaft 11 has a first shaft body 11a and a recess 11b. The first shaft body 11a has a first axis X1.
[0036] As shown in Fig. 2, spool 5 is attached to first shaft body 11a so as to rotate integrally therewith. A central portion of first shaft body 11a is rotatably supported by first side plate 31a via bearing 71a. An end portion of first shaft body 11a provided on the opposite side to handle 7 is rotatably supported by bearing member 31d via bearing 71b. Bearing member 31d is attached to second side plate 31b.
[0037] 2 and 4, the first shaft body 11a is inserted into the inner periphery of the pinion gear 10c. For example, a portion of the first shaft body 11a on the handle 7 side is inserted into the pinion gear 10c.
[0038] As shown in Fig. 4, an annular step portion 11c is provided at the end of the first shaft body 11a on the handle 7 side. The step portion 11c is formed on the outer circumferential surface of the end portion of the first shaft body 11a. The step portion 11c is disposed at a distance from the inner circumferential surface of the pinion gear 10c in the radial direction. A cylindrical member 21 is disposed in the step portion 11c.
[0039] The cylindrical member 21 restricts an engaging portion 13b of the connecting shaft 13, which will be described later, from moving radially within the recess 11b of the spool shaft 11. As shown in Fig. 4, the cylindrical member 21 is disposed radially between the end of the spool shaft 11 on the handle 7 side and the pinion gear 10c.
[0040] For example, the cylindrical member 21 is disposed radially between the step portion 11c of the first shaft body 11a and the inner circumferential surface of the pinion gear 10c. When the recess 11b of the spool shaft 11 and the engagement portion 13b of the connecting shaft 13 are engaged with each other, an end of the cylindrical member 21 is disposed on the outer circumferential surface of the annular portion 13d of the connecting shaft 13.
[0041] 2, 3, and 4, recess 11b is provided at an end of spool shaft 11. For example, recess 11b is provided at an end of first shaft body 11a on the handle 7 side. Recess 11b is a groove extending in the radial direction.
[0042] The connecting shaft 13 is configured to be rotatable relative to the reel body 3. As shown in Fig. 4, the connecting shaft 13 is rotatably supported relative to the reel body 3 via the spool shaft 11. As shown in Figs. 4 and 5, the connecting shaft 13 rotates integrally with the spool shaft 11. The connecting shaft 13 is connected to the spool shaft 11. For example, the connecting shaft 13 is connected to an end of the first shaft body 11a on the handle 7 side in the axial direction.
[0043] 3 and 4, the connecting shaft 13 has a second shaft body 13a, an engaging portion 13b, a first small diameter portion 13c, and a protrusion 13e. The connecting shaft 13 further has an annular portion 13d.
[0044] As shown in FIG. 4, the second shaft body 13a is disposed inside the rolling elements 15 in a radial direction relative to a second axis X2, which will be described later. The second shaft body 13a contacts the rolling elements 15. For example, the second shaft body 13a is formed in a cylindrical shape (see FIG. 3). The second shaft body 13a has a second axis X2. When the connecting shaft 13 is connected to the spool shaft 11, the second axis X2 is disposed concentrically with the first axis X1 of the spool shaft 11.
[0045] As shown in Figures 3 and 4, engaging portion 13b is provided on second shaft body 13a. For example, engaging portion 13b is provided on second shaft body 13a via first small diameter portion 13c. As shown in Figure 4, engaging portion 13b engages with recess 11b of spool shaft 11. For example, engaging portion 13b engages with recess 11b provided on the end of first shaft body 11a on the handle 7 side.
[0046] 3, the cross section of the engaging portion 13b is formed in a non-circular shape, for example, a rectangular shape. The rectangular engaging portion 13b and the groove-like recess 11b engage with each other, so that the second shaft body 13a of the connecting shaft 13 rotates integrally with the first shaft body 11a of the spool shaft 11.
[0047] As shown in Figures 3 and 4, the first small diameter portion 13c is provided between the second shaft body 13a and the engaging portion 13b. In detail, the first small diameter portion 13c is provided between the second shaft body 13a and the annular portion 13d. The first small diameter portion 13c is formed in a cylindrical shape. The outer diameter of the first small diameter portion 13c is smaller than the outer diameter of the second shaft body 13a. The annular portion 13d is provided between the engaging portion 13b and the first small diameter portion 13c. The outer diameter of the annular portion 13d is larger than the outer diameter of the first small diameter portion 13c.
[0048] As shown in Figures 3 and 4, the protrusion 13e is provided on the second shaft body 13a. For example, the protrusion 13e protrudes from the outer circumferential surface of the second shaft body 13a in the radial direction away from the second axis X2. The protrusion 13e is formed in an annular shape on the outer circumferential surface of the second shaft body 13a in the circumferential direction around the second axis X2. The protrusion 13e engages with a recess 49b of a second holder 49, which will be described later (see Figure 5).
[0049] In this embodiment, an example is shown in which the protrusion 13e is formed in an annular shape, but at least one protrusion 13e may be formed on the outer circumferential surface of the second shaft body 13a.
[0050] The one-way clutch unit 14 brakes the rotation of the spool shaft 11. In this embodiment, the one-way clutch unit 14 brakes the rotation of the connecting shaft 13, and brakes the rotation of the spool shaft 11 via the connecting shaft 13. As shown in FIG. 4, the one-way clutch unit 14 is attached to the connecting shaft 13. The one-way clutch unit 14 is disposed between the connecting shaft 13 and the protruding portion 33b of the first side cover 33 in the radial direction away from the second axis X2 of the connecting shaft 13.
[0051] 3 and 4, the one-way clutch unit 14 has a rolling element 15 and an outer member 17. As shown in Fig. 4, the rolling element 15 is disposed between the connecting shaft 13 and the outer member 17. For example, the rolling element 15 is disposed between the second shaft body 13a of the connecting shaft 13 and the outer member 17.
[0052] 4, the rolling element 15 comes into contact with the connecting shaft 13 in the radial direction away from the second axis X2 of the connecting shaft 13. For example, when the connecting shaft 13 is connected to the spool shaft 11, the rolling element 15 comes into contact with the second shaft body 13a of the connecting shaft 13 in the radial direction away from the first axis X1 of the spool shaft 11. When the connecting shaft 13 is not connected to the spool shaft 11, the rolling element 15 comes into contact with the second shaft body 13a of the connecting shaft 13 in the radial direction away from the second axis X2 of the connecting shaft 13.
[0053] With the rolling element 15 in contact with the connecting shaft 13, when the connecting shaft 13 rotates in the line winding direction, the rolling element 15 rotates relative to the outer member 17. That is, in this case, the rolling element 15 does not transmit the rotation of the connecting shaft 13 in the line winding direction to the outer member 17. On the other hand, when the connecting shaft 13 rotates in the line reeling direction, the rolling element 15 transmits the rotation of the connecting shaft 13 in the line reeling direction to the outer member 17.
[0054] The outer member 17 is configured to be rotatable integrally with the connecting shaft 13 only in one direction, in the circumferential direction about the second axis X2 of the connecting shaft 13. As shown in Fig. 5, the outer member 17 is provided with a first protrusion 41 (an example of a first external force receiving portion) that receives a first external force in the axial direction in which the second axis X2 of the connecting shaft 13 extends. The outer member 17 is further provided with a second protrusion 42 (an example of a second external force receiving portion) that receives a second external force acting in a direction opposite to the first external force.
[0055] The first external force is a pressing force acting from the first friction plate 18a to the first convex portion 41. The second external force is a pressing force acting from the second friction plate 18b to the second convex portion 42. For example, the distance between the first friction plate 18a and the second friction plate 18b changes due to the swinging of the operating lever 9. The pressing force acting on the first convex portion 41 and the second convex portion 42 changes in response to the change in the distance between the first friction plate 18a and the second friction plate 18b.
[0056] 4 and 5, the outer member 17, for example an outer ring 43 (an example of a retaining portion) described below, is disposed outside the rolling elements 15 in the radial direction away from the second axis X2 of the connecting shaft 13. The outer member 17, for example the outer ring 43, is rotatable with respect to the reel body 3. For example, the outer member 17, for example the outer ring 43, is rotatable with respect to the protruding portion 33b of the first side cover 33.
[0057] When the connecting shaft 13 rotates together with the spool shaft 11 in the line-releasing direction, the rolling element 15 transmits the rotation in the line-releasing direction to the outer member 17, e.g., the outer ring 43. In other words, the outer member 17, e.g., the outer ring 43, rotates integrally with the connecting shaft 13 only in the line-releasing direction. For this reason, in this embodiment, the above "one direction" corresponds to the "line-releasing direction".
[0058] 3 and 5, the outer member 17 has an outer ring 43 and a holder 45. The outer ring 43 holds the rolling elements 15. The outer ring 43 is disposed outside the rolling elements 15 in a radial direction away from the second axis X2 of the connecting shaft 13. The outer ring 43 is configured to be rotatable integrally with the connecting shaft 13 only in one direction in the circumferential direction around the second axis X2 of the connecting shaft 13.
[0059] 5, the holder 45 is provided on the outer ring 43. In detail, the holder 45 is provided on the outer ring 43 so as to cover the end of the connecting shaft 13. The holder 45 rotates integrally with the outer ring 43. The holder 45 is provided with a first convex portion 41 and a second convex portion 42.
[0060] For example, the holder 45 has a first holder 47 and a second holder 49. The first holder 47 is provided on the outer ring 43 so as to cover the tip end of the connecting shaft 13. The first holder 47 is provided on the outer ring 43 so as to cover one end of the outer ring 43. The first holder 47 is bonded or press-fitted to the outer ring 43. As a result, the first holder 47 rotates integrally with the outer ring 43.
[0061] 5, a first convex portion 41 is provided on the first holder 47. The first convex portion 41 protrudes from the first holder 47 in the axial direction in which the second axis X2 of the connecting shaft 13 extends. For example, the first convex portion 41 protrudes from the first holder 47 so that the second axis X2 passes through the first convex portion 41. The first convex portion 41 contacts the first friction plate 18a.
[0062] The first friction plate 18a is attached non-rotatably to the operating lever 9. As shown in Fig. 4 and Fig. 5, the first friction plate 18a is disposed between the first holder 47 and the operating lever 9 in the axial direction in which the second axis X2 of the connecting shaft 13 extends. The first friction plate 18a comes into contact with the first protrusion 41 and the operating lever 9 in the axial direction in which the second axis X2 of the connecting shaft 13 extends.
[0063] 5, the second holder 49 is provided on the outer ring 43 on the opposite side to the first holder 47 in the axial direction in which the second axis X2 of the connecting shaft 13 extends. The second holder 49 is provided on the outer ring 43 so as to cover the other end of the outer ring 43. The second holder 49 is bonded or press-fitted into the outer ring 43. This allows the second holder 49 to rotate integrally with the outer ring 43. That is, the first holder 47 and the second holder 49 rotate integrally with the outer ring 43.
[0064] The second holder 49 is provided with a second protrusion 42. The second protrusion 42 protrudes from the second holder 49 in the axial direction in which the second axis X2 of the connecting shaft 13 extends. For example, the second protrusion 42 is formed in an annular shape.
[0065] The second protrusion 42 contacts the second friction plate 18b. The second holder 49 is provided with a recess 49b. For example, the second holder 49 has a hole 49a. The recess 49b is formed in an annular shape on the inner circumferential surface of the hole 49a. The projection 13e of the connecting shaft 13 engages with the recess 49b.
[0066] 4 and 5, the at least one second friction plate 18b is non-rotatably attached to the protruding portion 33b of the first side cover 33. For example, the at least one second friction plate 18b includes a plurality of (e.g., two) second friction plates 18b.
[0067] The multiple (e.g., two) second friction plates 18b are disposed between the second holder 49 and the first seal member 19 in the axial direction in which the second axis X2 of the connecting shaft 13 extends. The multiple second friction plates 18b are disposed between the second holder 49 and a flange portion 33c provided on the inner circumferential surface of the protruding portion 33b in the axial direction in which the second axis X2 of the connecting shaft 13 extends.
[0068] As shown in Fig. 3, the multiple second friction plates 18b are annular plate members. As shown in Fig. 5, one of the second friction plates 18b contacts the second protruding portion 42 in the axial direction in which the second axis X2 of the connecting shaft 13 extends. The other second friction plate 18b contacts the flange portion 33c (see Fig. 4) of the protruding portion 33b in the axial direction in which the second axis X2 of the connecting shaft 13 extends.
[0069] 5, the first protrusion 41 and the second protrusion 42 contact the first friction plate 18a and the second friction plate 18b, respectively, in the axial direction in which the second axis X2 of the connecting shaft 13 extends. In this state, the first holder 47 and the second holder 49 are sandwiched by the first friction plate 18a and the second friction plate 18b. As a result, when the outer member 17 rotates, the rotation of the outer member 17 is braked by the first friction plate 18a and the second friction plate 18b.
[0070] As shown in Fig. 4, the first seal member 19 is disposed axially between the spool shaft 11 and the rolling elements 15. In this state, the first seal member 19 contacts the connecting shaft 13. The first seal member 19 is formed in an annular shape (see Fig. 3).
[0071] 4, the first seal member 19 is disposed between the spool shaft 11 and the one-way clutch unit 14 in the axial direction. For example, the first seal member 19 contacts the flange portion 33c of the protrusion portion 33b in the axial direction. The tip of the first seal member 19 is disposed between the spool shaft 11 and the rolling elements 15 in the axial direction. In this state, the tip of the first seal member 19, for example, the inner circumferential surface of the first seal member 19, contacts the first small diameter portion 13c of the connecting shaft 13.
[0072] 3 and 4, a positioning member 25 is disposed between the first seal member 19 and the bearing 61a. For example, the positioning member 25 is formed in a cylindrical shape. The positioning member 25 contacts the outer periphery of the first seal member 19 and the outer ring 43 of the bearing 61a in the axial direction. The positioning member 25 restricts the movement of the first seal member 19 in the axial direction.
[0073] 4, the second seal member 20 stops water from entering through a gap between the operating lever 9 and the protruding portion 33b. The second seal member 20 is disposed between the operating lever 9 and the protruding portion 33b in the radial direction. For example, the second seal member 20 is an O-ring.
[0074] Dual-bearing reel 1 having the above configuration includes reel body 3 and one-way clutch unit 14. In one-way clutch unit 14, outer member 17 receives a pressing force in the axial direction at first protrusion 41 (an example of a first external force receiving portion) of holder 45. This allows a braking force to be applied to outer member 17 in a stable manner.
[0075] Specifically, in the one-way clutch unit 14, the holder 45 has a first holder 47 and a second holder 49. The outer member 17 receives a pressing force in the axial direction at the first protruding portion 41 of the first holder 47. This allows a braking force to be applied to the outer member 17 in a stable manner.
[0076] Furthermore, in the one-way clutch unit 14, the outer member 17 receives a pressing force in the axial direction at the second protrusion 42 (an example of a second external force receiving portion) of the second holder 49. This allows a braking force to be applied to the outer member 17 in a stable manner.
[0077] Furthermore, in the one-way clutch unit 14, the outer member 17 is braked by the pressing force acting from the first friction plate 18a to the first convex portion 41 and the pressing force acting from the second friction plate 18b to the second convex portion 42. This allows the braking force to be applied to the outer member 17 in a stable manner.
[0078] Furthermore, in the one-way clutch unit 14, the first holder 47 and the second holder 49 are adhered or press-fitted to the outer ring 43, so that the first holder 47 and the second holder 49 can be appropriately attached to the outer ring 43.
[0079] Furthermore, in the one-way clutch unit 14, the projection 13e of the connecting shaft 13 engages with the recess 49b of the second holder 49. This allows the connecting shaft 13 to be appropriately positioned in the second holder 49.
[0080] (Variation 1) In the above embodiment, an example has been shown in which the first holder 47 and the second holder 49 are adhered or press-fitted to the outer ring 43. As shown in Fig. 6A, the first holder 47 and the second holder 49 may be screwed together to hold the outer ring 43 therebetween.
[0081] In this case, for example, a female screw portion 47a is formed in the first holder 47. A male screw portion 49c is formed in the second holder 49. The outer ring 43 is clamped between the first holder 47 and the second holder 49 by screwing the female screw portion 47a into the male screw portion 49c. The outer peripheral surface of the outer ring 43 and the inner peripheral surfaces of the first holder 47 and the second holder 49 may be bonded with an adhesive. With this configuration, the first holder 47 and the second holder 49 can be suitably attached to the outer ring 43.
[0082] (Variation 2) In the embodiment described above, an example is shown in which the first convex portion 41 is formed on the first holder 47 so that the second axis X2 passes through the first convex portion 41. Alternatively, as shown in FIG. 6B, an annular third convex portion 51 (an example of a first external force receiving portion) may be formed on the first holder 47. In this case, the second axis X2 passes through the inner periphery of the annular third convex portion 51. In this way, even if the annular third convex portion 51 is formed on the first holder 47, it is possible to stably apply a braking force to the outer member 17. Note that even in this case, the first holder 47 and the second holder 49 may be screwed together as in (Modification 1).
[0083] (Other embodiments) (A) In the above embodiment, an example in which the outer member 17 has the outer ring 43 and the holder 45 has been shown. Alternatively, as shown in FIG. 7, the outer member 17 may have only the outer ring 43. In this case, an annular fourth convex portion 52 (an example of a first external force receiving portion) and an annular fifth convex portion 53 (an example of a second external force receiving portion) are provided on the outer ring 43. For example, the annular fourth convex portion 52 and the annular fifth convex portion 53 are formed integrally with the outer ring 43. The annular fourth convex portion 52 contacts the first friction plate 18a. The annular fifth convex portion 53 contacts the second friction plate 18b. In this way, even if the outer member 17 is configured without using the holder 45, a braking force can be stably applied to the outer member 17.
[0084] (B) In the above embodiment, an example has been shown in which the first seal member 19 is disposed axially outside the one-way clutch unit 14. As shown in Fig. 8A, the one-way clutch unit 14 may be configured so that the first seal member 19 is included in the one-way clutch unit 14.
[0085] In this case, the one-way clutch unit 14 has a rolling element 15, an outer member 17, and a third seal member 22. The outer member 17 has an outer ring 43, and a holder 45 including a first holder 47 and a second holder 49.
[0086] An annular recess 49d is formed on the inner circumferential surface of the second holder 49. The outer circumferential portion of the third seal member 22 is disposed in the annular recess 49d. A tip of the third seal member 22, for example, an inner circumferential surface of the third seal member 22, contacts the connecting shaft 13, for example, the first small diameter portion 13c.
[0087] In this way, even if the one-way clutch unit 14 is configured to have the third seal member 22, a braking force can be stably applied to the outer member 17. Furthermore, in this configuration, the third seal member 22 can stop water flowing from the spool shaft 11 toward the rolling elements 15.
[0088] (C) In the other embodiment (B), as shown in FIG. 8A, the third seal member 22 is disposed between the rolling elements 15 and the second friction plate 18b. In this case, water flowing from the spool shaft 11 toward the rolling elements 15 may adhere to the second friction plate 18b, which may reduce the durability of the second friction plate 18b. To solve this problem, the one-way clutch unit 14 may be configured as shown in FIG. 8B. For example, the first holder 47 is disposed in the annular stepped portion 33d of the reel body 3. The annular stepped portion 33d is formed on the inner circumferential surface of the protruding portion 33b.
[0089] An opening end 47b (an example of a second external force receiving portion) of the first holder 47 is disposed facing the bottom surface of the annular step portion 33d. An annular second friction plate 18b is disposed between the opening end 47b of the first holder 47 and the bottom surface of the annular step portion 33d. The opening end 47b of the first holder 47 contacts the annular second friction plate 18b. The first holder 47 is sandwiched between the first friction plate 18a and the second friction plate 18b. The third seal member 22 is disposed in an annular recess 149d formed on the inner circumferential surface of the protruding portion 33b.
[0090] In this configuration, when the outer ring 43 and the first holder 47 constituting the outer member 17 rotate, the rotation of the outer member 17 is braked by the first friction plate 18a and the second friction plate 18b. Even with this configuration, a braking force can be applied to the outer member 17 in a stable manner.
[0091] In addition, in this configuration, the second friction plate 18b is disposed at a position that is out of the path of water flowing from the spool shaft 11 toward the rolling elements 15, so that it is possible to prevent water from adhering to the second friction plate 18b, thereby improving the durability of the second friction plate 18b.
[0092] (D) In the above embodiment, as shown in FIG. 4, the bearing 71a supports the spool shaft 11. The bearing 61a supports the pinion gear 10c. This defines the position of the first axis X1 of the spool shaft 11 that is inserted into the inner periphery of the pinion gear 10c. The connecting shaft 13 is engaged with the spool shaft 11. This causes the second axis X2 of the connecting shaft 13 to be disposed concentrically with the first axis X1 of the spool shaft 11.
[0093] In this case, depending on the connection accuracy of the connecting shaft 13 and the spool shaft 11, there is a risk of misalignment occurring between the second axis X2 of the connecting shaft 13 and the first axis X1 of the spool shaft 11. To solve this problem, as shown in Figure 9A, the one-way clutch unit 14 may be supported on the reel body 3 via a bearing 62. For example, the one-way clutch unit 14 is supported on the protruding portion 33b of the reel body 3 via the bearing 62.
[0094] The bearing 62 is disposed in the annular stepped portion 33d of the reel body 3. The bearing 62 supports the one-way clutch unit 14, for example, the outer ring 43 of the outer member 17. The outer ring 62a of the bearing 62 axially contacts the second friction plate 18b and the bottom surface of the stepped portion 33d of the protruding portion 33b in the axial direction in which the second axis X2 extends.
[0095] The first holder 47 is disposed on the annular step portion 33d of the reel body 3. An open end 47b (an example of a second external force receiving portion) of the first holder 47 is disposed facing the bottom surface of the annular step portion 33d. A bearing 62 and an annular second friction plate 18b are disposed between the open end 47b of the first holder 47 and the bottom surface of the annular step portion 33d. The open end 47b of the first holder 47 contacts the annular second friction plate 18b. The first holder 47 is sandwiched between the first friction plate 18a and the second friction plate 18b.
[0096] In this configuration, when the outer ring 43 and the first holder 47 constituting the outer member 17 rotate, the rotation of the outer member 17 is braked by the first friction plate 18a and the second friction plate 18b. Even with this configuration, a braking force can be applied to the outer member 17 in a stable manner.
[0097] In addition, in this configuration, the bearing 62 supports the outer ring 43 of the outer member 17, so that when the connecting shaft 13 is connected to the spool shaft 11, the second axis X2 of the connecting shaft 13 can be suitably positioned on the first axis X1 of the spool shaft 11.
[0098] (E) The first holder 47 of the outer member 17 of the alternative embodiment (D) may be configured as shown in Fig. 9B. In this case, a gap is provided between the opening end 47b of the first holder 47 and the bearing 62 in the axial direction.
[0099] The first holder 47 has a first protrusion 41 (an example of a first external force receiving portion) and a flange portion 47c (an example of a second external force receiving portion). The flange portion 47c protrudes in a radial direction away from the second axis X2 and extends in a circumferential direction around the second axis X2.
[0100] The flange portion 47c is disposed facing the end of the protruding portion 33b of the reel body 3 in the axial direction in which the second axis X2 extends. The second friction plate 18b is disposed axially between the flange portion 47c and the end of the protruding portion 33b. The flange portion 47c and the end of the protruding portion 33b contact the second friction plate 18b. Even with this configuration, the same effects as those of the other embodiment (D) can be obtained. (F) In the above embodiment and other embodiments, examples have been shown in which the spool shaft 11 is attached to the one-way clutch unit 14 via the connecting shaft 13. Alternatively, the connecting shaft 13 may be formed integrally with the spool shaft 11, thereby directly attaching the spool shaft 11 to the one-way clutch unit 14. In this case, the spool shaft 11 is considered to be a shaft member that is braked by the one-way clutch unit 14. [Explanation of symbols]
