[0002] A fishing reel, such as a double bearing reel disclosed in Patent Literature 1, has a reel main body, a spool shaft, and a one-way clutch. The spool shaft is rotatably supported to the reel main body.
[0003] The one-way clutch has a rolling body and an outer member. The rolling body is in contact with the spool shaft in the radial direction.

[0006] Patent Literature 1: Japanese Patent No. 6560903 SUMMARY
[0007] [Problems to be Solved by the Invention]
[0008] In the related art structure, the spool shaft is inserted into the rolling body of the one-way clutch. For example, in the case where a sealing member for the rolling body is desired to be disposed in the related art structure, the spool shaft is inserted into the inside of the rolling body in a state where the sealing member is disposed adjacent to the rolling body in the axial direction. In this case, there is a concern that the sealing member is wound into the inside of the rolling body when the spool shaft is inserted into the rolling body. That is, in the related art structure, there is a concern that water flowing from the spool shaft into the rolling body is inserted into the inside of the rolling body.
[0009] An object of the present application is to provide a fishing reel capable of improving the waterproof performance of a sealing member.
[0010] [Means for Solving the Problems]
[0011] A fishing reel according to an aspect of the present application has a reel main body, a first shaft member, a second shaft member, a rolling body, and an outer member. The first shaft member is rotatably supported to the reel main body. The second shaft member is connected to an end portion of the first shaft member in the axial direction in which the axis of the first shaft member extends. The second shaft member integrally rotates with the first shaft member.
[0012] The rolling body contacts the second shaft member in a radial direction away from the axis of the first shaft member. The outer member is disposed outside the rolling body in the radial direction. The outer member rotates integrally with the second shaft member in only one direction in a circumferential direction around the axis of the first shaft member.
[0013] In the fishing reel according to the present application, the second shaft member is inserted into the sealing member while being inserted into the rolling body. Thus, the sealing member can be disposed without being wound inside the rolling body as in the prior art. Accordingly, water flowing from the first shaft member to the rolling body can be blocked by the sealing member. Thus, the waterproof performance of the sealing member can be improved.
[0014] In the fishing reel according to another aspect of the present application, the first shaft member preferably has a recess provided at an end portion thereof. In this case, the second shaft member has a shaft body contacting the rolling body and an engaging portion provided at the shaft body and engaging with the recess. In this structure, the second shaft member can rotate integrally with the first shaft member by engaging the engaging portion of the second shaft member with the recess of the first shaft member.
[0015] The fishing reel according to another aspect of the present application preferably further has a sealing member. In this case, the sealing member is disposed between the first shaft member and the rolling body in an axial direction in which the axis of the first shaft member extends, and contacts the second shaft member. With this structure, water flowing from the first shaft member to the rolling body can be blocked by the sealing member.
[0016] In the fishing reel according to another aspect of the present application, the second shaft member preferably has a small-diameter portion. In this case, the small-diameter portion is provided between the shaft body and the engaging portion. The diameter of the small-diameter portion is smaller than that of the shaft body. The tip end of the sealing member contacts the small-diameter portion. In this structure, since the tip end of the sealing member contacts the small-diameter portion, water flowing from the first shaft member to the rolling body can be blocked by the sealing member.
[0017] In the fishing reel according to another aspect of the present application, the first shaft member is preferably a spool shaft. In this case, the outer member is subjected to a frictional force from a rotation-restricted member that is rotationally restricted with respect to the reel body. In this structure, since the first shaft member is a spool shaft, the second shaft member is connected to the spool shaft. In this case, water flowing from the spool shaft to the rolling body can be blocked by the sealing member.
[0018] [Effects of the Invention]
[0019] According to the present application, the waterproof performance of a sealing member can be improved in a fishing reel. Attached Figure Description

Detailed Implementation
[0026] Below, refer to the appendix. Figure 1 The embodiments of the double-bearing fishing reel 1 (an example of a fishing reel for fishing) according to the present invention will be described below. Figure 1 As shown, the double-bearing fishing reel 1 has a reel body 3, a spool 5, a handle 7, and an operating handle 9. (As shown...) Figure 2 As shown, the double-bearing fishing reel 1 also includes a spool shaft 11, a connecting shaft 13 (an example of a second shaft component), rolling elements 15, an external component 17, and a sealing component 19. The double-bearing fishing reel 1 also includes a cylindrical component 21. In this embodiment, the rolling elements 15 and the external component 17 constitute a one-way clutch 23.
[0027] Furthermore, axial direction refers to the direction in which the first axis X1 (an example of the axis) of the winding drum shaft 11 (an example of the first shaft component) extends. Radial direction refers to the direction perpendicular to and away from the first axis X1 of the winding drum shaft 11. Circumferential direction refers to the direction around the first axis X1 of the winding drum shaft 11.
[0028] like Figure 2As shown, the fishing reel main 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 disposed apart from each other in the axial direction. The first side plate 31a and the second side plate 31b are connected to each other 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 formed integrally.
[0029] The first side cover 33 covers the first side plate 31a. For example, the first side cover 33 has a cover main body 33a and a protruding portion 33b. The cover main body 33a covers the first side plate 31a between the handle 7 and the first side plate 31a. The protruding portion 33b protrudes from the cover main body 33a to the outside in the axial direction. The protruding portion 33b is formed in a cylindrical shape. The protruding portion 33b communicates from an inside space of the first side cover 33 and the first side plate 31a to an outside space. 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.
[0030] As shown, the handle 7 is a member for rotating the spool shaft 11. The handle 7 is mounted to the fishing reel main body 3. For example, the handle 7 is rotatably supported to the fishing reel main body 3 by a drive shaft 10a as shown. Figure 2
[0031] Figure 1 As shown, the handle 7 is a member for rotating the spool shaft 11. The handle 7 is mounted to the fishing reel main body 3. For example, the handle 7 is rotatably supported to the fishing reel main body 3 by a drive shaft 10a as shown. Figure 2
[0032] As shown, the handle 7 is a member for rotating the spool shaft 11. The handle 7 is mounted to the fishing reel main body 3. For example, the handle 7 is rotatably supported to the fishing reel main body 3 by a drive shaft 10a as shown. Figure 2
[0033] The drive shaft 10a is rotatably supported to the first side plate 31a and the first side cover 33. The drive shaft 10a is integrally rotated with the handle 7. The drive gear 10b is integrally rotated with the drive shaft 10a.
[0034] The pinion gear 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 gear 10c is engaged with the drive gear 10b. The pinion gear 10c is formed in a cylindrical shape. The spool shaft 11 is inserted into the inner peripheral portion of the pinion gear 10c.
[0035] The pinion gear 10c is guided in the axial direction of the spool shaft 11 by a clutch fork 12. Rotation is transmitted from the pinion gear 10c to the spool shaft 11 by engagement of an engagement pin 10d1 of the spool shaft 11 with an engagement recess 10d2 of the pinion gear 10c. In the case where the engagement of the engagement pin 10d1 with the engagement recess 10d2 is released, rotation of the pinion gear 10c is not transmitted to the spool shaft 11.
[0036] As shown in Figure 1 and Figure 2 , the operation handle 9 is attached to the reel body 3. For example, as shown in Figure 2 , the operation handle 9 is attached to the protruding portion 33b of the first side cover 33. In detail, the operation handle 9 is attached to the protruding portion 33b so as to be swingable with respect to the protruding portion 33b. By swinging of the operation handle 9, the outer member 17 is pushed in the axial direction. For example, by swinging of the operation handle 9, the outer member 17 is pushed in the axial direction through the first friction plate 18a.
[0037] The spool shaft 11 is integrally rotatable with the spool 5. As shown in Figure 2 , the spool shaft 11 is rotatably supported to the reel body 3. For example, the spool shaft 11 is rotatably supported to the reel body 3 by a plurality of bearings 71a, 71b.
[0038] As shown in Figure 2 , Figure 3 and Figure 4 , the spool shaft 11 has a first shaft body 11a and a recessed portion 11b. The first shaft body 11a has a first shaft center X1.
[0039] As shown in Figure 2 , the spool 5 is attached to the first shaft body 11a so as to be integrally rotatable. The central portion of the first shaft body 11a is rotatably supported to the first side plate 31a by the bearing 71a. The end portion of the first shaft body 11a provided on the side opposite to the handle 7 is rotatably supported to the bearing member 31d by the bearing 71b. The bearing member 31d is attached to the second side plate 31b.
[0040] As shown in Figure 2 and Figure 4 , the first shaft body 11a is inserted into the inner peripheral portion of the pinion gear 10c. For example, the portion of the first shaft body 11a on the handle 7 side is inserted into the pinion gear 10c.
[0041] As shown in Figure 4 , a ring-shaped step portion 11c is provided at the end portion of the handle 7 side of the first shaft body 11a. The step portion 11c is disposed apart from the inner peripheral surface of the pinion 10c in the radial direction. A cylindrical member 21 is disposed on the step portion 11c.
[0042] As shown in Figure 2 , Figure 3 and Figure 4 , a recessed portion 11b is provided at the end portion of the spool shaft 11. For example, the recessed portion 11b is provided at the end portion of the handle 7 side of the first shaft body 11a. The recessed portion 11b is a groove portion extending in the radial direction.
[0043] The connecting shaft 13 rotates integrally with the spool shaft 11. As shown in Figure 2 and Figure 4 , the connecting shaft 13 is connected to the spool shaft 11. For example, the connecting shaft 13 is connected to the end portion of the handle 7 side of the first shaft body 11a in the axial direction.
[0044] As shown in Figure 3 and Figure 4 , the connecting shaft 13 has a second shaft body 13a (an example of a shaft body), an engaging portion 13b, and a small-diameter portion 13c. The connecting shaft 13 also has a ring-shaped portion 13d. As shown in Figure 4 , the second shaft body 13a is disposed inside the rolling body 15 in the radial direction. The second shaft body 13a is in contact with the rolling body 15.
[0045] For example, as shown in Figure 3 and Figure 4 , the second shaft body 13a is formed in a cylindrical shape. The second shaft body 13a has a second axis X2. As shown in Figure 4 , in a state in which the connecting shaft 13 is connected to the spool shaft 11, the second axis X2 is disposed concentrically with the first axis XI of the spool shaft 11.
[0046] As shown in Figure 3 and Figure 4 , the engaging portion 13b is provided to the second shaft body 13a. For example, the engaging portion 13b is provided to the second shaft body 13a through the small-diameter portion 13c. As shown in Figure 4 , 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 first shaft body 11a.
[0047] As shown in Figure 3As shown, the cross-section of the engaging portion 13b is formed in a non-circular shape, for example, a rectangle. The rectangular engaging portion 13b engages with the groove-shaped recess 11b, allowing the second shaft body 13a of the connecting shaft 13 and the first shaft body 11a of the winding drum shaft 11 to rotate together.
[0048] like Figure 3 and Figure 4 As shown, a small-diameter portion 13c is disposed between the second shaft body 13a and the engaging portion 13b. More specifically, the small-diameter portion 13c is disposed between the second shaft body 13a and the annular portion 13d. The small-diameter portion 13c is cylindrical. The outer diameter of the small-diameter portion 13c is smaller than the outer diameter of the second shaft body 13a. The annular portion 13d is disposed between the engaging portion 13b and the small-diameter portion 13c. The outer diameter of the annular portion 13d is larger than the outer diameter of the small-diameter portion 13c.
[0049] The cylindrical component 21 restricts the engagement portion 13b of the connecting shaft 13 from moving radially within the recess 11b of the winding spool 11. For example... Figure 4 As shown, the cylindrical member 21 is radially disposed between the end of the spool 11 on the handle 7 side and the pinion 10c. 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 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.
[0050] like Figure 2 and Figure 4 As shown, a one-way clutch 23 is mounted on the connecting shaft 13. The one-way clutch 23 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.
[0051] like Figure 2 , Figure 3 and Figure 4 As shown, the one-way clutch 23 has a rolling element 15 and an external component 17. (As...) Figure 2 and Figure 4 As shown, the rolling element 15 is disposed between the connecting shaft 13 and the external component 17. For example, as Figure 4 As shown, the rolling element 15 is disposed between the second shaft body 13a of the connecting shaft 13 and the external component 17.
[0052] The rolling body 15 is in contact with the connecting shaft 13 in the radial direction. For example, in a state where the connecting shaft 13 is connected to the spool shaft 11, the rolling body 15 is in contact with the second shaft body 13a of the connecting shaft 13 in the radial direction away from the first shaft center XI of the spool shaft 11. In a state where the connecting shaft 13 is not connected to the spool shaft 11, the rolling body 15 is in contact with the second shaft body 13a of the connecting shaft 13 in the radial direction away from the second shaft center X2 of the connecting shaft 13.
[0053] In a state where the rolling body 15 is in contact with the connecting shaft 13, in a case where the connecting shaft 13 is rotated in the winding direction, the rolling body 15 is rotated with respect to the external member 17. That is, in this case, the rolling 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, in a case where the connecting shaft 13 is rotated in the unwinding direction, the rolling body 15 transmits the rotation of the connecting shaft 13 in the unwinding direction to the external member 17.
[0054] The external member 17 is configured to be integrally rotatable with the connecting shaft 13 in only one direction in the circumferential direction. For example, in a case where the connecting shaft 13 is rotated in the unwinding direction together with the spool shaft 11, the rolling body 15 transmits the rotation in the unwinding direction to the external member 17. In other words, the external member 17 is integrally rotatable with the connecting shaft 13 in only the unwinding direction. As a result, it is understood that, in the present embodiment, the above-described "one direction" corresponds to the "unwinding direction".
[0055] As shown in Figs. 1 and 2, the external member 17 is disposed on the outer side of the rolling body 15 in the radial direction. The external member 17 is rotatable with respect to the reel body 3. For example, the external member 17 is rotatable with respect to the protruding portion 33b of the first side cover 33. Figure 2 Figure 4 As shown in Figs. 1 and 2, the external member 17 is disposed on the outer side of the rolling body 15 in the radial direction. The external member 17 is rotatable with respect to the reel body 3. For example, the external member 17 is rotatable with respect to the protruding portion 33b of the first side cover 33.
[0056] The external member 17 is subjected to a frictional force from a rotation-restricted member that is restricted in rotation with respect to the reel body 3. For example, as shown in Figs. 1 and 2, the external member 17 is sandwiched by the first friction plate 18a and the second friction plate 18b in the axial direction. That is, the rotation of the external member 17 is braked by the first friction plate 18a and the second friction plate 18b. Figure 3 Figure 4 The first friction plate 18a is mounted to the operating handle 9 in a manner that the first friction plate 18a is not rotatable with respect to the operating handle 9. The first friction plate 18a is disposed between the external member 17 and the operating handle 9 in the axial direction. The first friction plate 18a is a ring-shaped plate member. The first friction plate 18a is in contact with the external member 17 and the operating handle 9 in the axial direction. The first friction plate 18a is not in contact with the rolling body 15.
[0057] The first friction plate 18a is mounted to the operating handle 9 in a manner that the first friction plate 18a is not rotatable with respect to the operating handle 9. The first friction plate 18a is disposed between the external member 17 and the operating handle 9 in the axial direction. The first friction plate 18a is a ring-shaped plate member. The first friction plate 18a is in contact with the external member 17 and the operating handle 9 in the axial direction. The first friction plate 18a is not in contact with the rolling body 15.
[0058] The second friction plate 18b is mounted to the protrusion 33b of the first side cover 33 in a manner that prevents it from rotating relative to the protrusion 33b of the first side cover 33. For example, multiple (e.g., two) second friction plates 18b are axially disposed between the outer member 17 and the sealing member 19. More specifically, multiple second friction plates 18b are axially disposed between the outer member 17 and the flange 33c, wherein the flange 33c is provided on the inner circumferential surface of the protrusion 33b.
[0059] Multiple second friction plates 18b are annular plate components. One second friction plate 18b contacts the outer component 17 in the axial direction, but does not contact the rolling element 15. The other second friction plate 18b contacts the flange portion 33c of the protrusion 33b in the axial direction.
[0060] like Figure 4 As shown, the sealing member 19 is axially positioned between the winding drum shaft 11 and the rolling element 15. In this state, the sealing member 19 is in contact with the connecting shaft 13.
[0061] like Figure 3 As shown, the sealing member 19 is formed in an annular shape. The outer periphery of the sealing member 19 is axially disposed between the winding drum shaft 11 and the outer component 17. For example, the outer periphery of the sealing member 19 contacts the flange portion 33c of the protrusion 33b in the axial direction. The top end of the sealing member 19 is axially disposed between the winding drum shaft 11 and the rolling element 15. In this state, the top end of the sealing member 19, for example, the inner circumferential surface of the sealing member 19, contacts the small-diameter portion 13c of the connecting shaft 13.
[0062] like Figure 3 and Figure 4 As shown, a positioning member 25 is disposed between the sealing 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 sealing member 19 and the outer ring of the bearing 61a in the axial direction. The axial movement of the sealing member 19 is restricted by the positioning member 25.
[0063] In the double-bearing fishing reel 1 with the above-described structure, firstly, the connecting shaft 13 is inserted into the rolling element 15 of the one-way clutch 23. Thus, the one-way clutch 23 and the connecting shaft 13 constitute a single unit.
[0064] In this state, the connecting shaft 13 is inserted into the sealing member 19 disposed in the protrusion 33b of the first side cover 33, and connected to the winding drum shaft 11. Accordingly, the sealing member 19 can be configured without being rolled into the inside of the rolling element 15 as in prior art structures. Therefore, water flowing from the winding drum shaft 11 to the rolling element 15 can be effectively blocked by the sealing member 19. That is, the waterproof performance of the sealing member 19 can be improved.
[0065] In addition, by engaging the engaging portion 13b of the connecting shaft 13 with the recessed portion 11b of the spool shaft 11, the connecting shaft 13 can be made to rotate integrally with the spool shaft 11.
[0066] In addition, the sealing member 19 is disposed between the spool shaft 11 and the rolling element 15 in the axial direction and is in contact with the connecting shaft 13, and thus water flowing from the spool shaft 11 to the rolling element 15 can be well blocked by the sealing member 19.
[0067] In addition, since the tip end of the sealing member 19 is in contact with the small-diameter portion 13c of the connecting shaft 13, water flowing from the spool shaft 11 to the rolling element 15 can be even better blocked by the sealing member 19.
[0068] In addition, even if the outer member 17 is a structure in which the first friction plate 18a and the second friction plate 18b are subjected to frictional force, the connecting shaft 13 can be inserted into the sealing member 19, and thus can be connected to the spool shaft 11. That is, even with the above-described structure, water flowing from the spool shaft 11 to the rolling element 15 can be well blocked by the sealing member 19.
