[0008] In the related art structure, the friction plate is in contact with the one-way clutch unit. In detail, the friction plate is in contact with an end surface of the outer member of the one-way clutch unit. In this case, since the plate is in contact with the end surface of the outer member without taking friction into consideration, it is difficult to stably apply a braking force to the outer member.
[0009] An object of the present application is to provide a one-way clutch unit of a fishing reel, which can stably apply a braking force to an outer member.
[0010] [Means for Solving the Problems]
[0011] A one-way clutch unit of a fishing reel according to one aspect of the present application brakes rotation of a shaft member of a fishing reel. The one-way clutch unit of the fishing reel has a rotation body and an outer member.

[0018] In the one-way clutch unit of the fishing reel according to another aspect of the present application, the first holding frame and the second holding frame are preferably bonded to or pressed into the holding portion. In this structure, the first holding frame and the second holding frame can be appropriately attached to the holding portion.
[0019] In the one-way clutch unit of the fishing reel according to another aspect of the present application, the first holding frame and the second holding frame preferably sandwich the holding portion by being screwed to each other. In this structure, the first holding frame and the second holding frame can be appropriately attached to the holding portion.
[0020] In the one-way clutch unit of the fishing reel according to another aspect of the present application, the first external force receiving portion preferably has a second protrusion protruding in the axial direction. In this structure, the external member receives the first external force in the axial direction on the second protrusion. Accordingly, the braking force can be stably applied to the external member.
[0021] In the one-way clutch unit of the fishing reel according to another aspect of the present application, a second external force receiving portion is preferably provided on the outer member, and receives a second external force acting in a direction opposite to the first external force.
[0022] In this structure, the outer member is 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. Accordingly, the braking force can be stably applied to the outer member.

DETAILED DESCRIPTION
[0042] Hereinafter, an embodiment of a double bearing reel 1 (an example of a fishing reel) to which the present application is applied will be described with reference to the drawings. As shown in FIG. 1, the double bearing reel 1 has a reel body 3, a spool 5, a handle 7, and an operating lever 9. As shown in FIG. 2, the double bearing reel 1 further has a spool shaft 11 (an example of a shaft member), a connecting shaft 13 (an example of a shaft member), and a one-way clutch unit 14. The double bearing reel 1 further has a 1st seal member 19 and a 2nd seal member 20. Figure 1 Figure 1 Figure 2
[0043] Furthermore, axial direction refers to the direction in which the first axis X1 of the spool shaft 11 extends. Radial direction refers to the direction perpendicularly away from the first axis X1 of the spool shaft 11. Circumferential direction refers to the direction around the first axis X1 of the spool shaft 11.
[0044] like Figure 2 As shown, the fishing 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 spaced apart from each other along the axial direction. The first side plate 31a and the second side plate 31b are connected together by 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.
[0045] 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 protrusion 33b. The cover body 33a covers the first side plate 31a between the handle 7 and the first side plate 31a. The protrusion 33b protrudes axially outward from the cover body 33a. The protrusion 33b is formed in a cylindrical shape. The protrusion 33b communicates with the external space from the internal space of the first side cover 33 and the first side plate 31a. The second side cover 35 covers the second side plate 31b. In detail, the second side cover 35 covers the second side plate 31b on the side opposite to the handle 7.
[0046] like Figure 2 As shown, the spool 5 is rotatably supported on the fishing reel body 3. For example, the spool 5 is mounted on the spool shaft 11 in a manner that allows it to rotate integrally with the spool shaft 11. That is, the spool 5 is rotatably supported on the fishing reel body 3 via the spool shaft 11.
[0047] Figure 1 The handle 7 shown is a component used to rotate the spool shaft 11. The handle 7 is mounted on the fishing reel body 3. For example, the handle 7 is... Figure 2 The drive shaft 10a shown is rotatably supported on the fishing reel body 3. 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.
[0048] like Figure 2 As shown, the rotation transmission mechanism 10 is disposed within the interior space of the first side cover 33 and the first side plate 31a. The rotation transmission mechanism 10 is a mechanism for transmitting the rotation of the handle 7 to the winding spool 11. The rotation transmission mechanism 10 has a drive shaft 10a, a drive gear 10b, and a pinion 10c.
[0049] The drive shaft 10a is rotatably supported to 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.
[0050] The pinion 10c is rotatably supported to the first side plate 31a and the first side cover 33 by a plurality of bearings 61a, 61b. The pinion 10c is engaged with the drive gear 10b. The pinion 10c is formed in a cylindrical shape. The spool shaft 11 is inserted through the inner peripheral portion of the pinion 10c.
[0051] The pinion 10c is guided in the axial direction along the spool shaft 11 by the clutch yoke 12. Rotation is transmitted from the pinion 10c to the spool shaft 11 by engagement of the engagement pin 10d1 of the spool shaft 11 and the engagement recess 10d2 of the pinion 10c. In the case where the engagement of the engagement pin 10d1 and the engagement recess 10d2 is released, rotation of the pinion 10c is not transmitted to the spool shaft 11.
[0052] As shown in Figure 1 and Figure 2 , the operation lever 9 is mounted to the reel main body 3. For example, as shown in Figure 2 , the operation lever 9 is mounted to the protruding portion 33b of the first side cover 33. In detail, the operation lever 9 is swingably mounted to the protruding portion 33b.
[0053] By swinging of the operation lever 9, the one-way clutch unit 14 is pushed in the axial direction. For example, by swinging of the operation lever 9, the one-way clutch unit 14 is pushed in the axial direction between the first friction plate 18a and the second friction plate 18b.
[0054] The spool shaft 11 rotates integrally with the spool 5. The spool shaft 11 is configured to be rotatable relative to the reel main body 3. As shown in Figure 2 , the spool shaft 11 is rotatably supported to the reel main body 3. For example, the spool shaft 11 is rotatably supported to the reel main body 3 by a plurality of bearings 71a, 71b.
[0055] As shown in Figure 2 , Figure 3 and Figure 4 , the spool shaft 11 has a first shaft body 11a and a recess 11b. The first shaft body 11a has a first shaft center X1.
[0056] As shown in Figure 2As shown, the spool 5 is integrally rotatably mounted on the first shaft body 11a. The central portion of the first shaft body 11a is rotatably supported on the first side plate 31a via a bearing 71a. The end of the first shaft body 11a located on the side opposite to the handle 7 is rotatably supported on a bearing member 31d via a bearing 71b. The bearing member 31d is mounted on the second side plate 31b.
[0057] like Figure 2 and Figure 4 As shown, the first shaft body 11a is inserted into the inner circumference of the pinion 10c. For example, the portion of the first shaft body 11a on the handle 7 side is inserted into the pinion 10c.
[0058] like Figure 4 As shown, an annular stepped portion 11c is provided at the end of the first shaft body 11a on the handle 7 side. The stepped portion 11c is formed on the outer peripheral surface of the end of the first shaft body 11a. The stepped portion 11c is arranged radially spaced from the inner peripheral surface of the pinion 10c. A cylindrical member 21 is disposed on the stepped portion 11c.
[0059] The cylindrical component 21 restricts the radial movement of the engaging portion 13b of the connecting shaft 13 (described later) within the recess 11b of the winding drum shaft 11. For example... Figure 4 As shown, the cylindrical component 21 is radially positioned between the end of the spool shaft 11 on the handle 7 side and the pinion 10c.
[0060] For example, the cylindrical member 21 is radially disposed between the stepped portion 11c of the first shaft body 11a and the inner circumferential surface of the pinion 10c. When the recess 11b of the winding spool 11 is engaged with the engaging portion 13b of the connecting shaft 13, the end of the cylindrical member 21 is disposed on the outer circumferential surface of the annular portion 13d of the connecting shaft 13.
[0061] like Figure 2 , Figure 3 and Figure 4 As shown, a recess 11b is provided at the end of the winding drum 11. For example, the recess 11b is provided at the end of the first shaft body 11a on the handle 7 side. The recess 11b is a groove extending radially.
[0062] The connecting shaft 13 is configured to rotate relative to the fishing reel body 3. For example... Figure 4 As shown, the connecting shaft 13 is rotatably supported on the fishing reel body 3 via the spool shaft 11. Figure 4 and Figure 5 As shown, the connecting shaft 13 rotates integrally with the winding drum shaft 11. The connecting shaft 13 is connected to the winding drum shaft 11. For example, the connecting shaft 13 is axially connected to the end of the first shaft body 11a on the handle 7 side.
[0063] As Figure 3 and Figure 4 shown, the connecting shaft 13 has a 2nd shaft body 13a, an engaging portion 13b, a 1st small diameter portion 13c, and a protrusion 13e. The connecting shaft 13 also has a ring-shaped portion 13d.
[0064] As Figure 4 shown, the 2nd shaft body 13a is disposed on the inner side of the rotating body 15 in the radial direction with respect to the 2nd shaft center X2 described later. The 2nd shaft body 13a is in contact with the rotating body 15. For example, the 2nd shaft body 13a is formed in a cylindrical shape (refer to Figure 3 ). The 2nd shaft body 13a has the 2nd shaft center X2. In a state where the connecting shaft 13 is connected to the spool shaft 11, the 2nd shaft center X2 is disposed concentrically with the 1st shaft center XI of the spool shaft 11.
[0065] As Figure 3 and Figure 4 shown, the engaging portion 13b is provided to the 2nd shaft body 13a. For example, the engaging portion 13b is provided to the 2nd shaft body 13a through the 1st small diameter portion 13c. As Figure 4 shown, the engaging portion 13b engages with the recessed portion 11b of the spool shaft 11. For example, the engaging portion 13b engages with the recessed portion 11b provided to the end portion of the handle 7 side of the 1st shaft body 11a.
[0066] As Figure 3 shown, the cross section of the engaging portion 13b is formed in a non-circular shape, for example, a rectangular shape. By the rectangular engaging portion 13b and the groove-shaped recessed portion 11b engaging with each other, the 2nd shaft body 13a of the connecting shaft 13 rotates integrally with the 1st shaft body 11a of the spool shaft 11.
[0067] As Figure 3 and Figure 4 shown, the 1st small diameter portion 13c is provided between the 2nd shaft body 13a and the engaging portion 13b. In detail, the 1st small diameter portion 13c is provided between the 2nd shaft body 13a and the ring-shaped portion 13d. The 1st small diameter portion 13c is formed in a cylindrical shape. The outer diameter of the 1st small diameter portion 13c is smaller than the outer diameter of the 2nd shaft body 13a. The ring-shaped portion 13d is provided between the engaging portion 13b and the 1st small diameter portion 13c. The outer diameter of the ring-shaped portion 13d is larger than the outer diameter of the 1st small diameter portion 13c.
[0068] As Figure 3 and Figure 4 shown, the protrusion 13e is provided to the 2nd shaft body 13a. For example, the protrusion 13e protrudes from the outer peripheral surface of the 2nd shaft body 13a in the radial direction away from the 2nd shaft center X2. The protrusion 13e is formed in a ring shape on the outer peripheral surface of the 2nd shaft body 13a in the circumferential direction around the 2nd shaft center X2. The protrusion 13e engages with the recessed portion 49b of the 2nd holder 49 described later (refer toFigure 5 ).
[0069] In this embodiment, an example is shown where the protrusion 13e is formed in a ring shape, but at least one protrusion 13e may also be formed on the outer peripheral surface of the second axis body 13a.
[0070] 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, thereby braking the rotation of the spool shaft 11 via the connecting shaft 13. Figure 4 As shown, a one-way clutch unit 14 is mounted on a connecting shaft 13. The one-way clutch unit 14 is arranged radially away from the second axis X2 of the connecting shaft 13 between the connecting shaft 13 and the protrusion 33b of the first side cover 33.
[0071] like Figure 3 and Figure 4 As shown, the one-way clutch unit 14 has a rotating body 15 and an external component 17. (As indicated...) Figure 4 As shown, the rotating body 15 is disposed between the connecting shaft 13 and the external member 17. For example, the rotating body 15 is disposed between the second shaft body 13a of the connecting shaft 13 and the external member 17.
[0072] like Figure 5 As shown, the rotating body 15 contacts the connecting shaft 13 radially away from the second axis X2. For example, when the connecting shaft 13 is connected to the spool shaft 11, the rotating body 15 contacts the second shaft body 13a of the connecting shaft 13 radially 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 rotating body 15 contacts the second shaft body 13a of the connecting shaft 13 radially away from the second axis X2 of the connecting shaft 13.
[0073] When the rotating body 15 is in contact with the connecting shaft 13, the rotating body 15 rotates relative to the external member 17 when the connecting shaft 13 rotates in the winding direction. That is, in this case, the rotating body 15 does not transmit the rotation of the connecting shaft 13 in the winding direction to the external member 17. On the other hand, when the connecting shaft 13 rotates in the unwinding direction, the rotating body 15 transmits the rotation of the connecting shaft 13 in the unwinding direction to the external member 17.
[0074] The external member 17 is configured such that it can rotate integrally with the connecting shaft 13 in only one direction around the second axis X2 of the connecting shaft 13 in the circumferential direction. For example... Figure 4As shown, a first protrusion 41 (an example of a first external force bearing portion) is provided on the outer member 17, which bears the first external force in the axial direction extending from the second axis X2 of the connecting shaft 13. A second protrusion 42 (an example of a second external force bearing portion) is also provided on the outer member 17, which is used to bear a second external force acting in the opposite direction to the first external force.
[0075] The first external force is the pushing force exerted by the first friction plate 18a on the first protrusion 41. The second external force is the pushing force exerted by the second friction plate 18b on the second protrusion 42. For example, by swinging the operating lever 9, the gap between the first friction plate 18a and the second friction plate 18b changes. In response to the change in the gap between the first friction plate 18a and the second friction plate 18b, the pushing force exerted on the first protrusion 41 and the second protrusion 42 changes.
[0076] like Figure 5 and Figure 3 As shown, the outer member 17, such as the outer ring 43 (an example of a retaining part) described later, is arranged radially away from the second axis X2 of the connecting shaft 13 on the outside of the rotating body 15. The outer member 17, such as the outer ring 43, is rotatable relative to the fishing reel body 3. For example, the outer member 17, such as the outer ring 43, is rotatable relative to the protrusion 33b of the first side cover 33.
[0077] When the connecting shaft 13 and the winding drum shaft 11 rotate together in the unwinding direction, the rotating body 15 transmits the rotation in the unwinding direction to the external component 17, such as the outer ring 43. In other words, the external component 17, such as the outer ring 43, rotates only in the unwinding direction along with the connecting shaft 13. Accordingly, in this embodiment, the aforementioned "one direction" corresponds to the "unwinding direction".
[0078] like Figure 5 and Figure 5 As shown, the outer member 17 has an outer ring 43 and a retainer 45. The outer ring 43 holds the rotating body 15. The outer ring 43 is arranged radially away from the second axis X2 of the connecting shaft 13 on the outside of the rotating body 15. The outer ring 43 is configured in a manner that allows it to rotate integrally with the connecting shaft 13 in only one direction in the circumferential direction about the second axis X2 of the connecting shaft 13.
[0079] like Figure 5 As shown, a retainer 45 is disposed on the outer ring 43. Specifically, the retainer 45 is disposed on the outer ring 43 such that it covers the end of the connecting shaft 13. The retainer 45 rotates integrally with the outer ring 43. A first protrusion 41 and a second protrusion 42 are provided on the retainer 45.
[0080] For example, the retainer 45 has a first retainer 47 and a second retainer 49. The first retainer 47 is provided to the outer ring 43 in a manner of covering the top end portion of the connecting shaft 13. The first retainer 47 is provided to the outer ring 43 in a manner of covering one end portion of the outer ring 43. The first retainer 47 is adhered or pressed into the outer ring 43. Accordingly, the first retainer 47 rotates integrally with the outer ring 43.
[0081] As shown in FIG. 1, the first retainer 47 is provided with a first protrusion 41. The first protrusion 41 protrudes from the first retainer 47 in the axial direction in which the second shaft center X2 of the connecting shaft 13 extends. For example, the first protrusion 41 protrudes from the first retainer 47 in a manner that the second shaft center X2 passes through the first protrusion 41. The first protrusion 41 is in contact with the first friction plate 18a. Figure 4
[0082] As shown in FIG. 1, the first friction plate 18a is disposed between the first retainer 47 and the operating lever 9 in the axial direction in which the second shaft center X2 of the connecting shaft 13 extends. The first friction plate 18a is in contact with the first protrusion 41 and the operating lever 9 in the axial direction in which the second shaft center X2 of the connecting shaft 13 extends. Figure 5 Figure 5 As shown in FIG. 1, the first friction plate 18a is disposed between the first retainer 47 and the operating lever 9 in the axial direction in which the second shaft center X2 of the connecting shaft 13 extends. The first friction plate 18a is in contact with the first protrusion 41 and the operating lever 9 in the axial direction in which the second shaft center X2 of the connecting shaft 13 extends.
[0083] As shown in FIG. 1, the second retainer 49 is provided to the outer ring 43 in a manner of being located on the side opposite to the first retainer 47 in the axial direction in which the second shaft center X2 of the connecting shaft 13 extends. The second retainer 49 is provided to the outer ring 43 in a manner of covering the other end portion of the outer ring 43. The second retainer 49 is adhered or pressed into the outer ring 43. Accordingly, the second retainer 49 rotates integrally with the outer ring 43. That is, the first retainer 47 and the second retainer 49 rotate integrally with the outer ring 43. Figure 4 As shown in FIG. 1, the second retainer 49 is provided to the outer ring 43 in a manner of being located on the side opposite to the first retainer 47 in the axial direction in which the second shaft center X2 of the connecting shaft 13 extends. The second retainer 49 is provided to the outer ring 43 in a manner of covering the other end portion of the outer ring 43. The second retainer 49 is adhered or pressed into the outer ring 43. Accordingly, the second retainer 49 rotates integrally with the outer ring 43. That is, the first retainer 47 and the second retainer 49 rotate integrally with the outer ring 43.
[0084] The second protrusion 42 protrudes from the second retainer 49 in the axial direction in which the second shaft center X2 of the connecting shaft 13 extends. For example, the second protrusion 42 is formed in a ring shape.
[0085] The second protrusion 42 is in contact with the second friction plate 18b. The second retainer 49 is provided with a recessed portion 49b. For example, the second retainer 49 has a hole portion 49a. The recessed portion 49b is formed in a ring shape on the inner peripheral surface of the hole portion 49a. The protrusion 13e of the connecting shaft 13 is engaged with the recessed portion 49b.
[0086] Figure 5 As shown in FIG. 1, at least one second friction plate 18b is mounted to the protruding portion 33b of the first side cover 33 in a manner of being unable to rotate. For example, the at least one second friction plate 18b includes a plurality of (for example, two) second friction plates 18b. Figure 3
[0087] A plurality of (for example, two) second friction plates 18b are arranged in the axial direction in which the second shaft center X2 of the connecting shaft 13 extends, between the second holder 49 and the first seal member 19. The plurality of second friction plates 18b are arranged in the axial direction in which the second shaft center X2 of the connecting shaft 13 extends, between the second holder 49 and the flange portion 33c provided to the inner peripheral surface of the protruding portion 33b.
[0088] As shown in Figure 5 , the plurality of second friction plates 18b are annular plate members. As shown in Figure 4 , one of the second friction plates 18b is in contact with the second protruding portion 42 in the axial direction in which the second shaft center X2 of the connecting shaft 13 extends. The other of the second friction plates 18b is in contact with the flange portion 33c of the protruding portion 33b (see Figure 5 ) in the axial direction in which the second shaft center X2 of the connecting shaft 13 extends.
[0089] As shown in Figure 4 , the first protruding portion 41 and the second protruding portion 42 are in contact with the first friction plate 18a and the second friction plate 18b, respectively, in the axial direction in which the second shaft center 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. Accordingly, in the case where 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.
[0090] As shown in Figure 3 , the first seal member 19 is arranged in the axial direction between the spool shaft 11 and the rotating body 15. In this state, the first seal member 19 is in contact with the connecting shaft 13. The first seal member 19 is formed in an annular shape (see Figure 4 ).
[0091] As shown in Figure 3 , the first seal member 19 is arranged in the axial direction between the spool shaft 11 and the one-way clutch unit 14. For example, the first seal member 19 is in contact with the flange portion 33c of the protruding portion 33b in the axial direction. The tip end of the first seal member 19 is arranged in the axial direction between the spool shaft 11 and the rotating body 15. In this state, the tip end of the first seal member 19, for example, the inner peripheral surface of the first seal member 19 is in contact with the first small diameter portion 13c of the connecting shaft 13.
[0092] As shown in Figure 4 and Figure 4 , a positioning member 25 is arranged 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 is in contact with the outer peripheral portion of the first seal member 19 and the outer ring of the bearing 61a in the axial direction. The movement of the first seal member 19 in the axial direction is limited by the positioning member 25.
[0093] As Figure 6A shown, the second seal member 20 is configured to prevent water from entering from a gap between the operating lever 9 and the protrusion 33b. The second seal member 20 is radially disposed between the operating lever 9 and the protrusion 33b. For example, the second seal member 20 is an O-ring.
[0094] The dual-bearing reel 1 having the above-described structure has the reel main body 3 and the one-way clutch unit 14. In the one-way clutch unit 14, the outer member 17 receives a pressing force in the axial direction on the first protrusion 41 (an example of the first outer force receiving portion) of the retainer 45. Accordingly, it is possible to stably apply a braking force to the outer member 17.
[0095] In detail, in the one-way clutch unit 14, the retainer 45 has a first retainer 47 and a second retainer 49. The outer member 17 receives a pressing force in the axial direction on the first protrusion 41 of the first retainer 47. Accordingly, it is possible to stably apply a braking force to the outer member 17.
[0096] In addition, in the one-way clutch unit 14, the outer member 17 receives a pressing force in the axial direction on the second protrusion 42 (an example of the second outer force receiving portion) of the second retainer 49. Accordingly, it is possible to stably apply a braking force to the outer member 17.
[0097] In addition, in the one-way clutch unit 14, the outer member 17 is braked by a pressing force acting on the first protrusion 41 from the first friction plate 18a and a pressing force acting on the second protrusion 42 from the second friction plate 18b. Accordingly, it is possible to stably apply a braking force to the outer member 17.
[0098] In addition, in the one-way clutch unit 14, since the first retainer 47 and the second retainer 49 are adhered or pressed into the outer ring 43, it is possible to appropriately install the first retainer 47 and the second retainer 49 to the outer ring 43.
[0099] In addition, in the one-way clutch unit 14, the protrusion 13e of the connecting shaft 13 is engaged with the recess 49b of the second retainer 49. Accordingly, it is possible to appropriately position the connecting shaft 13 to the second retainer 49.
[0100] (Modified Example 1)
[0101] In the embodiment, an example of a case where the first retainer 47 and the second retainer 49 are adhered or pressed into the outer ring 43 is shown. As Figure 6B shown, it is possible to sandwich the outer ring 43 by screwing the first retainer 47 and the second retainer 49 to each other.
[0102] In this case, for example, an internally threaded portion 47a is formed on the first holder 47. An externally threaded portion 49c is formed on the second holder 49. By screwing the internally threaded portion 47a and the externally threaded portion 49c, the outer ring 43 is sandwiched by the first holder 47 and the second holder 49. Further, the outer circumferential surface of the outer ring 43 and the inner circumferential surfaces of the first holder 47 and the second holder 49 can be adhered together by an adhesive. With this structure, the first holder 47 and the second holder 49 can be properly attached to the outer ring 43.
[0103] (Modified Example 2)
[0104] In the embodiment, an example is shown in which the first protrusion 41 is formed on the first holder 47 so that the second axis X2 passes through the first protrusion 41. Instead of this, as shown in Figure 7 a ring-shaped third protrusion 51 (an example of the first external force receiving portion) can be formed on the first holder 47. In this case, the second axis X2 passes through the inner circumferential portion of the ring-shaped third protrusion 51. In this way, even if the ring-shaped third protrusion 51 is formed on the first holder 47, the braking force can be stably applied to the outer member 17. Further, in this case, the first holder 47 and the second holder 49 can be screwed as in (Modified Example 1).
[0105] (Other Embodiments)
[0106] (A) In the embodiment, an example is shown in which the outer member 17 has the outer ring 43 and the holder 45. Instead of this, as shown in Figure 8A the outer member 17 can have only the outer ring 43. In this case, a ring-shaped fourth protrusion 52 (an example of the first external force receiving portion) and a ring-shaped fifth protrusion 53 (an example of the second external force receiving portion) are provided to the outer ring 43. For example, the ring-shaped fourth protrusion 52 and the ring-shaped fifth protrusion 53 are formed integrally with the outer ring 43. The ring-shaped fourth protrusion 52 contacts the first friction plate 18a. The ring-shaped fifth protrusion 53 contacts the second friction plate 18b. In this way, even if the outer member 17 is configured without using the holder 45, the braking force can be stably applied to the outer member 17.
[0107] (B) In the embodiment, an example is shown in which the first seal member 19 is disposed on the axial outer side of the one-way clutch unit 14. As shown in Figure 8A the one-way clutch unit 14 can be configured so that the first seal member 19 is included in the one-way clutch unit 14.
[0108] In this case, the one-way clutch unit 14 has the rotating body 15, the outer member 17, and the third seal member 22. The outer member 17 has the outer race 43 and the retainer 45 including the first retainer 47 and the second retainer 49.
[0109] The annular recessed portion 49d is formed on the inner peripheral surface of the second retainer 49. The outer peripheral portion of the third seal member 22 is arranged on the annular recessed portion 49d. The tip end of the third seal member 22, for example, the inner peripheral surface of the third seal member 22 is in contact with the connecting shaft 13, for example, the first small-diameter portion 13c.
[0110] Thus, even if the one-way clutch unit 14 is configured in a manner that the third seal member 22 is provided, the braking force can be stably applied to the outer member 17. In addition, in this configuration, the water flowing from the spool shaft 11 to the rotating body 15 can be blocked by the third seal member 22.
[0111] (C) In the other embodiment (B), as shown in Figure 8B the third seal member 22 is arranged between the rotating body 15 and the second friction plate 18b. In this case, the water flowing from the spool shaft 11 to the rotating body 15 can adhere to the second friction plate 18b, and it can be possible that the durability of the second friction plate 18b is decreased. To solve this problem, as shown in Figure 4 the one-way clutch unit 14 can be configured. For example, the first retainer 47 is arranged on the annular stepped portion 33d of the reel main body 3. The annular stepped portion 33d is formed on the inner peripheral surface of the protruding portion 33b.
[0112] The open end 47b (an example of the second external force receiving portion) of the first retainer 47 is arranged in a manner that the bottom surface of the annular stepped portion 33d is faced. The annular second friction plate 18b is arranged between the open end 47b of the first retainer 47 and the bottom surface of the annular stepped portion 33d. The open end 47b of the first retainer 47 is in contact with the annular second friction plate 18b. The first retainer 47 is sandwiched by the first friction plate 18a and the second friction plate 18b. The third seal member 22 is arranged on the annular recessed portion 149d formed on the inner peripheral surface of the protruding portion 33b.
[0113] In this configuration, in a case where the outer race 43 and the first retainer 47 configuring 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 such a configuration, the braking force can be stably applied to the outer member 17.
[0114] In addition, in this configuration, since the second friction plate 18b is arranged at a position deviated from the path of the water flowing from the spool shaft 11 to the rotating body 15, the water can be prevented from adhering to the second friction plate 18b. Accordingly, the durability of the second friction plate 18b can be improved.
[0115] (D) In the embodiment, as shown in Figure 9A the bearing 71a supports the spool shaft 11. The bearing 61a supports the pinion 10c. Thereby, the position of the first shaft center XI of the spool shaft 11 inserted into the inner peripheral portion of the pinion 10c is determined. The connecting shaft 13 is engaged with the spool shaft 11. Thereby, the second shaft center X2 of the connecting shaft 13 is arranged concentrically with the first shaft center XI of the spool shaft 11.
[0116] In this case, depending on the connection accuracy of the connecting shaft 13 and the spool shaft 11, it is possible that a deviation occurs between the second shaft center X2 of the connecting shaft 13 and the first shaft center XI of the spool shaft 11. To solve this problem, as shown in Figure 9B the one-way clutch unit 14 can be supported to the reel body 3 by the bearing 62. For example, the one-way clutch unit 14 is supported to the protruding portion 33b of the reel body 3 by the bearing 62.
[0117] The bearing 62 is arranged at the annular stepped portion 33d of the reel body 3. The bearing 62 supports the outer ring 43 of the one-way clutch unit 14, for example, the outer member 17. The outer ring 62a of the bearing 62 is in contact with the second friction plate 18b and the bottom surface of the stepped portion 33d of the protruding portion 33b in the axial direction in the second shaft center X2.
[0118] The first retainer 47 is arranged at the annular stepped portion 33d of the reel body 3. The open end 47b (an example of the second external force receiving portion) of the first retainer 47 is arranged in a manner facing the bottom surface of the annular stepped portion 33d. The bearing 62 and the annular second friction plate 18b are arranged between the open end 47b of the first retainer 47 and the bottom surface of the annular stepped portion 33d. The open end 47b of the first retainer 47 is in contact with the annular second friction plate 18b. The first retainer 47 is sandwiched by the first friction plate 18a and the second friction plate 18b.
[0119] In this structure, in the case where the outer ring 43 of the outer member 17 and the first retainer 47 constituting the one-way clutch unit 14 rotate, the rotation of the outer member 17 is braked by the first friction plate 18a and the second friction plate 18b. Even with such a structure, the braking force can be stably applied to the outer member 17.
[0120] Further, in this structure, since the bearing 62 supports the outer ring 43 of the outer member 17, in the state where the connecting shaft 13 is connected to the spool shaft 11, the second shaft center X2 of the connecting shaft 13 can be appropriately arranged on the first shaft center XI of the spool shaft 11.
[0121] (E) The first retainer 47 of the outer member 17 of the other embodiment (D) can also be as shown in is configured as shown. In this case, a gap is provided between the opening end 47b of the first retainer 47 and the axial direction of the bearing 62.
[0122] The first retainer 47 has the first protruding portion 41 (an example of the first external force receiving portion) and a flange portion 47c (an example of the 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.
[0123] The flange portion 47c is disposed in a manner facing the end portion 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 between the flange portion 47c and the axial direction of the end portion of the protruding portion 33b. The flange portion 47c and the end portion of the protruding portion 33b are in contact with the second friction plate 18b. Even with such a structure, the same effects as those of the other embodiment (D) can be obtained.
[0124] (F) In the described embodiment and the other embodiments, an example in which the spool shaft 11 is mounted to the one-way clutch unit 14 through the connecting shaft 13 is shown. Instead, the spool shaft 11 can be directly mounted to the one-way clutch unit 14 by forming the connecting shaft 13 and the spool shaft 11 as one body. In this case, the spool shaft 11 is understood as an axle member that is braked by the one-way clutch unit 14.
