AI Technical Summary
In existing fishing reels, the support structure of the handle shaft is not effective in suppressing the wobbling of the reel body, and the rotation is not smooth, resulting in sliding resistance.
The bearing employs a dual-bearing structure, which restricts the movement of the outer ring of the bearing through spacers and limiting components, reduces the internal clearance of the bearing, and uses positioning and elastic components to adjust the preload, ensuring the stability and smooth rotation of the bearing.
It effectively suppresses the wobble of the handle shaft relative to the winding wheel body, reduces sliding resistance, achieves smooth rotation of the handle shaft, and improves the user experience.

TECHNICAL FIELD
[0001] The present application relates to a support structure of a fishing reel. BACKGROUND
[0002] In the conventional fishing reel, such as a double-bearing reel, a support structure is disclosed for rotatably supporting a handle shaft to a reel main body (right frame) (see, for example, Patent Document 1). In the support structure, a force applying member is disposed between the tip end of the handle shaft and the axial direction of the right frame. With the force applying member, the wobble of the handle shaft in the axial direction is suppressed.
[0003] Patent Document 1: Japanese Patent Application Publication No. 2009-005637
[0004] In the conventional support structure of the double-bearing reel, the wobble of the handle shaft in the axial direction is suppressed by disposing the force applying member between the tip end of the handle shaft and the axial direction of the right frame. In this case, the handle shaft is rotated in a state where the tip end of the handle shaft is pushed by the force applying member, so a sliding resistance is generated between the tip end of the handle shaft and the force applying member. Due to the sliding resistance, the handle shaft as a member having a first portion can not be smoothly rotated with respect to the right frame as a member having a second portion. SUMMARY
[0005] The present application has been made in view of the above problems, and it is an object to provide a support structure of a fishing reel capable of suppressing the wobble suppression of a first portion with respect to a second portion and smoothly rotating the first portion with respect to the second portion.
[0006] The support structure of a fishing reel according to an aspect of the present application includes a first portion, a second portion, a first bearing and a second bearing, a spacer, and a restriction member. The first portion is formed in a shaft shape. The first portion has an outer peripheral surface. The second portion has an inner peripheral surface. The inner peripheral surface is disposed opposite to the outer peripheral surface in a radial direction from a shaft center of the first portion. The first bearing and the second bearing are disposed in parallel with each other in an axial direction along the shaft center between the outer peripheral surface of the first portion and the inner peripheral surface of the second portion.
[0007] The spacer is disposed between an inner ring of the first bearing and an inner ring of the second bearing. The restriction member restricts movement of one of the outer ring of the first bearing and the outer ring of the second bearing in a direction in which the one of the outer ring of the first bearing and the outer ring of the second bearing is away from the other of the outer ring of the first bearing and the outer ring of the second bearing, so that an axial interval of the outer ring of the first bearing and the outer ring of the second bearing is smaller than an axial interval of the inner ring of the first bearing and the inner ring of the second bearing.
[0008] In the support structure of the fishing reel, the spacer is disposed between the inner ring of the first bearing and the inner ring of the second bearing. In this state, the movement of one of the outer rings of the first bearing and the second bearing is restricted by the restriction member in a direction in which the one of the outer rings of the first bearing and the second bearing is separated from the other of the outer rings of the first bearing and the second bearing. Thus, the axial interval of the outer rings of the first bearing and the second bearing becomes smaller than the axial interval of the inner rings of the first bearing and the second bearing.
[0009] Thus, the movement of the outer ring of the first bearing or the outer ring of the second bearing is restricted by the restriction member in a direction in which the outer ring of the first bearing or the outer ring of the second bearing is separated from the other. Thus, the inner clearance of the first bearing and the second bearing becomes small, so that the wobble of the first portion with respect to the second portion can be suppressed. In addition, in this case, the sliding resistance as in the prior art is not generated in the first portion, so that the first portion can be smoothly rotated with respect to the second portion.
[0010] Preferably, the support structure of the fishing reel according to the other aspect of the present application further includes a positioning member. The positioning member positions the inner ring of the first bearing, the inner ring of the second bearing, and the spacer in the axial direction with respect to the first portion.
[0011] In this case, the first bearing, the second bearing, and the spacer can be easily positioned in the axial direction with respect to the first portion by the positioning member.
[0012] Preferably, in the support structure of the fishing reel according to the other aspect of the present application, the first portion has a first abutting surface. One of the inner ring of the first bearing and the inner ring of the second bearing abuts on the first abutting surface in the axial direction. The positioning member positions the other of the inner ring of the first bearing and the inner ring of the second bearing at a predetermined position with respect to the first abutting surface.
[0013] In this case, the first bearing, the second bearing, and the spacer can be surely positioned in the axial direction with respect to the first portion by the positioning member and the first abutting surface.
[0014] Preferably, in the support structure of the fishing reel according to the other aspect of the present application, the second portion has a second abutting surface. The other of the outer ring of the first bearing and the outer ring of the second bearing abuts on the second abutting surface in the axial direction.
[0015] In this case, the first bearing and the second bearing can be easily positioned in the axial direction with respect to the second portion.
[0016] Preferably, the support structure of the fishing reel according to the other aspect of the present application further includes an elastic member. The elastic member is disposed between the other of the outer ring of the first bearing and the outer ring of the second bearing and the second portion in the axial direction.
[0017] In this case, the elastic member is configured to apply a pre-load to the first bearing and the second bearing, and the pre-load can be easily adjusted. In addition, when vibration is input to the first bearing and the second bearing from the outside, the vibration can be absorbed by the elastic member.
[0018] The fishing reel according to an aspect of the present application includes a spool for winding a fishing line, a handle assembly operated to wind the fishing line on the spool, and the above-described support structure disposed between the spool and the handle assembly.
[0019] The support structure includes a drive shaft connected to the handle assembly, and a reel body rotatably supporting the drive shaft. The first portion of the support structure is included in the drive shaft. The second portion of the support structure is included in the reel body.
[0020] Thus, even if the support structure is composed of the drive shaft and the reel body, the same effects as described above can be obtained.
[0021] The fishing reel according to an aspect of the present application includes a spool for winding a fishing line, a handle assembly operated to wind the fishing line on the spool, and the above-described support structure disposed between the spool and the handle assembly.
[0022] Thus, even if the support structure is composed of the handle shaft and the handle grip of the handle assembly, the same effects as described above can be obtained.
[0023] Effects of the Invention
[0024] According to the present application, in the support structure of the fishing reel, the first portion can be prevented from wobbling with respect to the second portion, and the first portion can be smoothly rotated with respect to the second portion. BRIEF DESCRIPTION OF DRAWINGS

[0036] A dual bearing reel 1 (an example of a fishing reel) of an embodiment of the present application, as shown in Figs. 1 and 2, has a reel body 3, a spool 5, a handle assembly 7, a first support structure 9 (refer to Fig. 3), and a second support structure 11 (refer to Fig. 4). Figure 1 Figure 2 Figure 2
[0037] The reel body 3 is configured to be mountable to a fishing rod. As shown in Fig. 3, the reel body 3 rotatably supports a handle shaft 31 via the first support structure 9. As shown in Fig. 4, the reel body 3 has a frame 11, a first side cover 13, and a second side cover 15. Figure 2 Figure 1
[0038] As shown in Fig. 3, the frame 11 has a first side plate 17, a second side plate 19, and a connecting portion 21. The first side plate 17 and the second side plate 19 are disposed apart from each other in an axial direction along an axis X1 of the spool shaft. The connecting portion 21 connects the first side plate 17 and the second side plate 19. The first side plate 17, the second side plate 19, and the connecting portion 21 are integrally formed. Figure 3
[0039] As shown in Fig. 3, the first side cover 13 and the second side cover 15 cover both side portions of the frame 11. The first side cover 13 and the second side cover 15 are respectively mounted to the both side portions of the frame 11. For example, the first side cover 13 is mounted to the first side plate 17 on a side opposite to the handle assembly 7. The second side cover 15 is mounted to the second side plate 19 between the handle assembly 7 and the second side plate 19. The second side cover 15 has a boss portion 15a. The handle shaft 31 (refer to Fig. 2) is inserted through the boss portion 15a. Figure 1 Figure 2
[0040] As shown in Figure 1 and Figure 2 , the first support structure 9 is arranged between the second side plate 19 and the handle assembly 7. Further, a rotation transmission mechanism (not shown in the drawings) that transmits the rotation of the handle shaft 31 to the spool shaft is arranged between the second side plate 19 and the second side cover 15. For example, the rotation transmission mechanism includes a drive gear and a planetary gear, etc.
[0041] The fishing line is wound around the spool 5. As shown in Figure 1 , the spool 5 is arranged between the first side plate 17 and the second side plate 19. The spool 5 is fixed to the spool shaft in a manner that it can rotate integrally with the spool shaft. The spool shaft is configured to be rotatable relative to the reel body 3. For example, the spool shaft is configured to be rotatable relative to the first side plate 17 and the second side plate 19.
[0042] As shown in Figure 1 , the handle assembly 7 is operated in order to wind the fishing line around the spool 5. The handle assembly 7 is rotatably assembled to the reel body 3. For example, the handle assembly 7 is rotatably assembled to the reel body 3 via the handle shaft 31 (refer to Figure 2 ).
[0043] The handle assembly 7 has a handle arm 23, a handle knob 25. The handle arm 23 is assembled to the handle shaft 31 in a manner that it rotates integrally with the handle shaft 31 (refer to Figure 2 ). The handle knob 25 is rotatably assembled to the handle arm 23.
[0044] The first support structure 9 supports the handle shaft 31 in a manner that the handle shaft 31 is rotatable relative to the reel body 3. As shown in Figure 1 and Figure 2 , the first support structure 9 is arranged between the spool 5 and the handle assembly 7. For example, the first support structure 9 is arranged between the second side plate 19 of the frame 11 and the handle assembly 7.
[0045] As shown in Figure 4 and Figure 5 , the first support structure 9 has the handle shaft 31 (an example of a first portion), the reel body 3 (an example of a second portion), a first bearing 33 and a second bearing 34, a first spacer 35, a first positioning member 37, a first limiting member 39. As shown in Figure 4 , the first support structure 9 further has a third bearing 41, a sealing member 42.
[0046] The handle shaft 31 is formed in a shaft shape. The handle shaft 31 is linked to the handle assembly 7 (refer to Figure 1 ). For example, one end portion of the handle shaft 31 is inserted through the boss portion 15a (refer to Figure 1The inner circumference of the handle shaft 31. The end of one end of the handle shaft 31 is connected to the handle arm 23 of the handle assembly 7 (see reference). Figure 1 They can be connected in a rotating manner.
[0047] like Figure 2 As shown, the handle shaft 31 is rotatably supported on the winding reel body 3. Figure 5 As shown, the handle shaft 31 is rotatably supported on the second side plate 19 of the winding reel body 3 (frame 11) via a first bearing 33 and a second bearing 34. Furthermore, the handle shaft 31 is supported via a third bearing 41 (see reference 3). Figure 4 The boss portion 15a of the second side cover 15 is rotatably supported (see reference). Figure 1 ).
[0048] like Figure 5 As shown, the handle shaft 31 has a shaft body 43 and a mounting portion 45. The shaft body 43 is substantially formed in a shaft shape. The shaft body 43 is rotatably supported by a boss portion 15a of the second side cover 15 via a third bearing 41 (see reference). Figure 1 ).
[0049] The mounting portion 45 forms one end of the handle shaft 31. The mounting portion 45 protrudes from the end of the shaft body 43 in the axial direction along the axis X2 of the handle shaft 31. The mounting portion 45 is rotatably supported by the mounting portion 47 (described later) of the second side plate 19 via the first bearing 33 and the second bearing 34.
[0050] like Figure 6A As shown, the assembly part 45 is essentially cylindrical. The assembly part 45 has a large-diameter part 45a and a small-diameter part 45b. The axis X2 of the handle shaft 31 passes through the center of the large-diameter part 45a and the center of the small-diameter part 45b.
[0051] A large-diameter portion 45a is provided at the end of the shaft body 43. The large-diameter portion 45a forms the base end of the mounting portion 45. A small-diameter portion 45b protrudes from the large-diameter portion 45a axially along the axis X2 of the handle shaft 31. The small-diameter portion 45b has an outer peripheral surface 45b1 (an example of the outer peripheral surface of the first part) and an internal thread portion 45b2. The internal thread portion 45b2 is formed on the inner peripheral surface of the small-diameter portion 45b. The outer diameter of the small-diameter portion 45b is smaller than the outer diameter of the large-diameter portion 45a.
[0052] By forming the large-diameter portion 45a and the small-diameter portion 45b in this way, the end face of the large-diameter portion 45a forms a first annular surface 45a1 (an example of the first abutment surface) that extends in a ring around the axis X2 of the handle shaft 31. That is, the handle shaft 31 (the large-diameter portion 45a of the assembly portion 45) includes the first annular surface 45a1.
[0053] like Figure 3 , Figure 5 and Figure 6AAs shown, the winding wheel body 3 has a fitted portion 47. For example, the 2nd side plate 19 has the fitted portion 47. The fitted portion 47 is concavely formed at the 2nd side plate 19.
[0054] As shown, Figure 6A the fitted portion 47 has a large-diameter hole portion 47a and a small-diameter hole portion 47b. The axis X2 of the handle shaft 31 passes through the center of the large-diameter hole portion 47a and the center of the small-diameter hole portion 47b. The large-diameter hole portion 47a is formed at the opening side of the fitted portion 47. The inner peripheral surface 47a1 (an example of the inner peripheral surface of the 2nd portion) of the large-diameter hole portion 47a is arranged to face the outer peripheral surface 45b1 of the fitted portion 45 on the handle shaft 31 in the radial direction away from the axis X2 of the handle shaft 31.
[0055] The small-diameter hole portion 47b is concavely formed at the bottom of the large-diameter hole portion 47a. The inner diameter of the small-diameter hole portion 47b is smaller than the inner diameter of the large-diameter hole portion 47a.
[0056] By thus forming the large-diameter hole portion 47a and the small-diameter hole portion 47b, the bottom of the large-diameter hole portion 47a forms a 2nd annular surface 47a2 (an example of the 2nd abutting surface) extending annularly around the axis X2 of the handle shaft 31. That is, the winding wheel body 3 (the fitted portion 47) includes the 2nd annular surface 47a2.
[0057] As shown, Figure 4 , Figure 5 and Figure 6A the 1st bearing 33 and the 2nd bearing 34 are arranged side by side with each other in the axial direction along the axis X2 of the handle shaft 31 between the outer peripheral surface 45b1 of the handle shaft 31 (the fitted portion 45) and the inner peripheral surface 47a1 of the winding wheel body 3 (the fitted portion 47).
[0058] For example, as shown, Figure 6A the 1st bearing 33 and the 2nd bearing 34 are arranged between the outer peripheral surface 45b1 of the fitted portion 45 (the small-diameter portion 45b) and the inner peripheral surface 47a1 of the large-diameter hole portion 47a of the fitted portion 47 in the radial direction away from the axis X2 of the handle shaft 31. The 1st bearing 33 and the 2nd bearing 34 are arranged side by side with each other at intervals in the axial direction along the axis X2 of the handle shaft 31.
[0059] In detail, the 1st bearing 33 has an inner ring 33a, an outer ring 33b, and a rolling body 33c arranged between the inner ring 33a and the outer ring 33b. The 2nd bearing 34 has an inner ring 34a, an outer ring 34b, and a rolling body 34c arranged between the inner ring 34a and the outer ring 34b.
[0060] As shown, Figure 6AAs shown, the inner ring 33a of the first bearing 33 and the inner ring 34a of the second bearing 34 are spaced apart from each other along the axial direction of the handle shaft 31 axis X2. The outer ring 33b of the first bearing 33 and the outer ring 34b of the second bearing 34 are spaced apart from each other along the axial direction of the handle shaft 31 axis X2.
[0061] The inner rings 33a of the first bearing 33 and 34a of the second bearing 34 are in contact with the outer peripheral surface 45b1 of the assembly part 45 (small diameter part 45b). Along the axial direction of the axis X2 of the handle shaft 31, the first annular surface 45a1 of the handle shaft 31 (assembly part 45) abuts against the inner ring 33a of the first bearing 33.
[0062] The outer ring 33b of the first bearing 33 and the outer ring 34b of the second bearing 34 are in contact with the inner circumferential surface 47a1 of the large-diameter hole 47a of the assembly part 47. Along the axial direction of the axis X2 of the handle shaft 31, the second annular surface 47a2 of the winding wheel body 3 (assembly part 47) abuts against the outer ring 34b of the second bearing 34.
[0063] like Figure 4 As shown, the third bearing 41 is disposed on the outer peripheral surface 31b of the handle shaft 31 and the boss portion 15a of the second side cover 15 (see reference). Figure 1 Between the inner circumferential surfaces of the bearing 31 and the handle shaft 31. For example, the inner ring of the third bearing 41 is fitted to the outer circumferential surface 31b of the handle shaft 31 via a cylindrical member 48. The outer ring of the third bearing 41 is fitted to the boss portion 15a of the second side cover 15 (see reference). Figure 1 The inner circumference of ).
[0064] like Figure 4 , Figure 5 and Figure 6A As shown, the first spacer 35 is disposed between the inner ring 33a of the first bearing 33 and the inner ring 34a of the second bearing 34. For example, the first spacer 35 is formed in an annular shape. The first spacer 35 is disposed on the outer peripheral surface 45b1 of the mounting portion 45 (small diameter portion 45b) between the inner ring 33a of the first bearing 33 and the inner ring 34a of the second bearing 34 in the axial direction.
[0065] like Figure 6A As shown, when the first spacer 35 is in contact with the inner rings 33a of the first bearing 33 and 34a of the second bearing 34, the axial length of the inner rings 33a of the first bearing 33, 34a of the second bearing 34, and the first spacer 35 is longer than the axial length of the small-diameter portion 45b of the assembly portion 45. The axial length of the small-diameter portion 45b of the assembly portion 45 can also be interpreted as the axial length from the first annular surface 45a1 of the assembly portion 45 to the end of the small-diameter portion 45b of the assembly portion 45.
[0066] With this configuration, the inner ring 33a of the first bearing 33, the inner ring 34a of the second bearing 34, and the first spacer 35 are positioned to the handle shaft 31 in the axial direction along the axis X2 of the handle shaft 31 in a state where the outer peripheral surface 45b1 of the small-diameter portion 45b of the fitting portion 45 is fitted. The inner ring 34a of the second bearing 34 protrudes from the end of the small-diameter portion 45b of the fitting portion 45.
[0067] As shown in FIG. 6, the first positioning member 37 positions the inner ring 33a of the first bearing 33, the inner ring 34a of the second bearing 34, and the first spacer 35 to the handle shaft 31 in the axial direction along the axis X2 of the handle shaft 31. The first positioning member 37 positions the inner ring 34a of the second bearing 34 to the predetermined position with respect to the first annular surface 45a1. The first positioning member 37 is attached to the fitting portion 45 of the handle shaft 31. For example, the first positioning member 37 is attached to the small-diameter portion 45b of the fitting portion 45. Figure 6A
[0068] As shown in FIG. 6, the first positioning member 37 has a main body portion 37a, a flange portion 37b. The main body portion 37a is formed in a cylindrical shape. The main body portion 37a has an external thread portion 37a1. The external thread portion 37a1 is formed on the outer peripheral surface of the main body portion 37a. The external thread portion 37a1 is threadedly engaged with an internal thread portion 45b2 provided on the inner peripheral surface of the small-diameter portion 45b. The flange portion 37b is provided in a circular plate shape in parallel with the main body portion 37a. The flange portion 37b annularly protrudes from the outer peripheral surface 45b1 of the main body portion 37a. The flange portion 37b abuts against the inner ring 34a of the second bearing 34. Figure 6B By screwing the external thread portion 37a1 of the main body portion 37a into the internal thread portion 45b2 of the small-diameter portion 45b, the flange portion 37b positions the inner ring 34a of the second bearing 34 to the predetermined position with respect to the first annular surface 45a1. Thus, the inner ring 33a of the first bearing 33, the inner ring 34a of the second bearing 34, and the first spacer 35 are positioned to the handle shaft 31 in the axial direction along the axis X2 of the handle shaft 31.
[0069] Here, in a state where the first limiting member 39 is not attached, the axial length of the gap between the outer ring 33b of the first bearing 33, the outer ring 34b of the second bearing 34, the outer ring 33b of the first bearing 33, and the outer ring 34b of the second bearing 34 is slightly shorter than the axial length of the large-diameter hole portion 47a of the fitting portion 47. With this configuration, the outer ring 33b of the first bearing 33 is slightly recessed from the opening end of the large-diameter hole portion 47a of the fitting portion 47 in the axial direction along the axis X2 of the handle shaft 31.
[0070] As shown in FIG. 6, the first positioning member 37 has a main body portion 37a, a flange portion 37b. The main body portion 37a is formed in a cylindrical shape. The main body portion 37a has an external thread portion 37a1. The external thread portion 37a1 is formed on the outer peripheral surface of the main body portion 37a. The external thread portion 37a1 is threadedly engaged with an internal thread portion 45b2 provided on the inner peripheral surface of the small-diameter portion 45b. The flange portion 37b is provided in a circular plate shape in parallel with the main body portion 37a. The flange portion 37b annularly protrudes from the outer peripheral surface 45b1 of the main body portion 37a. The flange portion 37b abuts against the inner ring 34a of the second bearing 34.
[0071] Figure 5 As shown, the sealing member 42 is arranged between the first limiting member 39 and the second side plate 19 of the winding wheel main body 3 (block 11). For example, the sealing member 42 is arranged between the recessed portions 19a of the second side plate 19 in a state of being pressed by the first limiting member 39.
[0072] As shown, the first limiting member 39 is fitted to the winding wheel main body 3. For example, as shown in Figure 2 Figure 5 and Figure 6A As shown, the first limiting member 39 is fixed to the second side plate 19 in a state of abutting against the outer ring 33b of the first bearing 33 by the threaded member 40.
[0073] Thus, the first limiting member 39 restricts the movement of the outer ring 33b of the first bearing 33 in the axial direction along the axis X2 of the handle shaft 31. For example, as shown in Figure 6A
[0074] Thus, the first limiting member 39 restricts the movement of the outer ring 33b of the first bearing 33 in a direction in which the outer ring 33b of the first bearing 33 is separated from the outer ring 34b of the second bearing 34, and thus the axial interval between the outer ring 33b of the first bearing 33 and the outer ring 34b of the second bearing 34 becomes smaller than the axial interval between the inner ring 33a of the first bearing 33 and the inner ring 34a of the second bearing 34. That is, the gap between the outer ring 33b of the first bearing 33 and the outer ring 34b of the second bearing 34 becomes small. Thus, the movement between the inner and outer rings of the first bearing 33 and the second bearing 34 is pressed.
[0075] The first support structure 9 having the above-described structure is fitted as follows. First, the sealing member 42 is arranged to the second side plate 19. Next, the first bearing 33, the first spacer 35, and the second bearing 34 are arranged to the outer peripheral surface 45bl of the fitting portion 45 (small-diameter portion 45b) of the handle shaft 31. In this state, the first positioning member 37 is fitted to the fitting portion 45 (small-diameter portion 45b) of the handle shaft 31. Thus, the first bearing 33, the first spacer 35, and the second bearing 34 are positioned to the handle shaft 31 by the first positioning member 37.
[0076] Next, the first bearing 33, the first spacer 35, the second bearing 34, the first positioning member 37, and the fitting portion 45 of the handle shaft 31 are arranged to the fitted portion 47 (large-diameter hole portion 47a) of the second side plate 19. In this state, the first limiting member 39 is fitted to the second side plate 19. Thus, the handle shaft 31 is rotatably supported with respect to the second side plate 19.
[0077] Next, the inner ring of the third bearing 41 is fitted to the handle shaft 31. In this state, the second side cover 15 (the boss portion 15a) is fitted to the outer ring of the third bearing 41. Thus, the handle shaft 31 is rotatably supported with respect to the second side cover 15. Further, the assembly of the components of the rotation transmission mechanism is omitted here.
[0078] In the first supporting structure 9 of the double bearing bobbin winder 1 described above, the movement of the outer ring 34b of the second bearing 34 in the direction in which the outer ring 34b of the second bearing 34 is separated from the outer ring 33b of the first bearing 33 is restricted by the first restriction member 39. Thus, the inner clearances of the first bearing 33 and the second bearing 34 are reduced. Thus, the wobble of the handle shaft 31 with respect to the bobbin winder main body 3 (the second side plate 19) can be suppressed. Further, in this case, the handle shaft 31 does not generate the sliding resistance as in the prior art, so the handle shaft 31 can be smoothly rotated with respect to the bobbin winder main body 3 (the second side plate 19).
[0079] <Second Embodiment>
[0080] In the first embodiment described above, an example in which the double bearing bobbin winder 1 is provided with the first supporting structure 9 is described. The double bearing bobbin winder 1 can also be provided with a handle fitting body 107 including a second supporting structure 109 as shown in Figs. 1 to 3 and Figs. 7 to 9. Here, the second supporting structure 109 can be used in combination with the first supporting structure 9 described above, or can be used alone without the first supporting structure 9 described above. Further, the same structures as in the first embodiment described above are omitted here. Figure 1 Figure 7A As described in the first embodiment, the handle fitting body 107 is coupled to the handle shaft 31. As shown in Figs. 1 to 3 and Figs. 7 to 9, the handle fitting body 107 has the second supporting structure 109. For example, the handle fitting body 107 has the handle arm 23, a handle shaft 24 (an example of the first portion) constituting the second supporting structure 109, and a handle grip 25 (an example of the second portion) constituting the second supporting structure 109. That is, the handle fitting body 107 has the handle arm 23 and the second supporting structure 109.
[0081] As described in the first embodiment, the handle fitting body 107 is coupled to the handle shaft 31. As shown in Figs. 1 to 3 and Figs. 7 to 9, the handle fitting body 107 has the second supporting structure 109. For example, the handle fitting body 107 has the handle arm 23, a handle shaft 24 (an example of the first portion) constituting the second supporting structure 109, and a handle grip 25 (an example of the second portion) constituting the second supporting structure 109. That is, the handle fitting body 107 has the handle arm 23 and the second supporting structure 109. Figure 7A The handle arm 23 is fitted to the handle shaft 31 so as to rotate integrally with the handle shaft 31. The handle shaft 24 is fitted to the handle arm 23. The second supporting structure 109 supports the handle grip 25 so that the handle grip 25 is rotatable with respect to the handle shaft 24.
[0082] As shown in Figs. 1 to 3 and Figs. 7 to 9, the second supporting structure 109 is provided to the handle arm 23. The second supporting structure 109 has the handle shaft 24, the handle grip 25, a fourth bearing 133 and a fifth bearing 134, and a second spacer 135 (see Fig. 8).
[0083] Figure 7A As shown in Figs. 1 to 3 and Figs. 7 to 9, the second supporting structure 109 is provided to the handle arm 23. The second supporting structure 109 has the handle shaft 24, the handle grip 25, a fourth bearing 133 and a fifth bearing 134, and a second spacer 135 (see Fig. 8). Figure 7B ), second positioning component 137, second limiting component 139.
[0084] The handle shaft 24 is formed in the shape of a shaft. The handle shaft 24 is mounted on the handle arm 23. The handle shaft 24 rotatably supports the handle handle 25. The handle shaft 24 rotatably supports the handle handle 25 via the fourth bearing 133 and the fifth bearing 134.
[0085] For example, the handle shaft 24 has a shaft body 143 and a mounting portion 145. The shaft body 143 is substantially formed in the shape of a shaft. One end of the shaft body 143 is mounted to the handle arm 23. The mounting portion 145 is provided at the other end of the shaft body 143.
[0086] The structure of the mounting portion 145 of the handle shaft 24 is substantially the same as that of the mounting portion 45 of the handle shaft 31 in the first embodiment. Therefore, the structure of the mounting portion 145 of the handle shaft 24 will be briefly described. The mounting portion 145 rotatably supports the handle handle 25 via the fourth bearing 133 and the fifth bearing 134. The mounting portion 145 is substantially cylindrical.
[0087] like Figure 7B As shown, the assembly part 145 has a large-diameter part 145a and a small-diameter part 145b. The large-diameter part 145a is provided at the end of the shaft body 143. The small-diameter part 145b has an outer peripheral surface 145b1 (an example of the outer peripheral surface of the first part) and an internal thread part 145b2 formed on the inner peripheral surface.
[0088] By forming the large-diameter portion 145a and the small-diameter portion 145b in this way, the end face of the large-diameter portion 145a forms a third annular surface 145a1 (an example of the first abutment surface) extending in a ring around the axis X3 of the handle shaft 24. That is, the handle shaft 24 (assembly portion 145) includes the third annular surface 145a1. The inner ring 133a of the fourth bearing 133 abuts against the third annular surface 145a1 axially.
[0089] like Figure 7A As shown, the handle 25 has a first handle body 147 and a second handle body 148. The first handle body 147 is the part that the angler grips. The first handle body 147 has a hole 147a. The second handle body 148 is threaded into the hole 147a of the first handle body 147.
[0090] The second handle body 148 has a first cylindrical portion 149 and a second cylindrical portion 150. A handle shaft 24 is disposed inside the first cylindrical portion 149 and the second cylindrical portion 150. A shaft body 143 is disposed in the first cylindrical portion 149. The first handle body 147 abuts against the first cylindrical portion 149. The outer diameter of the first cylindrical portion 149 is larger than the outer diameter of the second cylindrical portion 150.
[0091] The second cylindrical portion 150 is integrally formed with the first cylindrical portion 149. The shaft body 143 and the mounting portion 145 are disposed in the second cylindrical portion 150. The second cylindrical portion 150 has a small-diameter bore portion 150a and a large-diameter bore portion 150b. The axis X3 of the handle shaft 24 passes through the center of the small-diameter bore portion 150a and the center of the large-diameter bore portion 150b.
[0092] like Figure 7A As shown, a small-diameter bore 150a is formed on the side of the handle arm 23. Figure 7B As shown, the shaft body 143 and the large-diameter portion 145a are disposed inside the small-diameter bore portion 150a. The inner diameter of the small-diameter bore portion 150a is smaller than the inner diameter of the large-diameter bore portion 150b.
[0093] like Figure 7A As shown, the large-diameter bore 150b is formed on the side away from the handle arm 23. (As indicated...) Figure 7B As shown, a small diameter portion 145b is disposed inside the large diameter bore portion 150b. The inner circumferential surface 150b1 of the large diameter bore portion 150b (an example of the inner circumferential surface of the second part) is configured to face the outer circumferential surface 145b1 of the handle shaft 24 (small diameter portion 145b) in a radial direction away from the axis X3 of the handle shaft 24.
[0094] By forming the small-diameter bore 150a and the large-diameter bore 150b in this way, the bottom of the large-diameter bore 150b forms a fourth annular surface 150b2 (an example of the second abutment surface) extending in a ring around the axis X3 of the handle shaft 24. That is, the handle 25 (the second handle body 148) includes the fourth annular surface 150b2. The outer ring 133b of the fourth bearing 133 abuts against the fourth annular surface 150b2 axially.
[0095] like Figure 7B As shown, the fourth bearing 133 has an inner ring 133a, an outer ring 133b, and a rolling element 133c disposed between the inner ring 133a and the outer ring 133b. The fifth bearing 134 has an inner ring 134a, an outer ring 134b, and a rolling element 134c disposed between the inner ring 134a and the outer ring 134b.
[0096] The fourth bearing 133 and the fifth bearing 134 are disposed radially between the outer peripheral surface 145b1 (outer peripheral surface 145b1 of the small diameter portion 145b) of the handle shaft 24 and the inner peripheral surface 150b1 (inner peripheral surface 150b1 of the large diameter bore portion 150b) of the handle handle 25. The fourth bearing 133 and the fifth bearing 134 are arranged side by side with each other in the axial direction along the axis X3 of the handle shaft 24 between the outer peripheral surface 145b1 of the handle shaft 24 and the inner peripheral surface 150b1 of the handle handle 25.
[0097] The inner ring 133a of the fourth bearing 133 and the inner ring 134a of the fifth bearing 134 are spaced apart from each other in the axial direction along the axis X3 of the handle shaft 24. The outer ring 133b of the fourth bearing 133 and the outer ring 134b of the fifth bearing 134 are spaced apart from each other in the axial direction along the axis X3 of the handle shaft 24.
[0098] The inner ring 133a of the fourth bearing 133 and the inner ring 134a of the fifth bearing 134 are in contact with the outer peripheral surface 145b1 (outer peripheral surface 145b1 of the small diameter portion 145b) of the handle shaft 24. The inner ring 133a of the fourth bearing 133 abuts against the third annular surface 145a1 of the handle shaft 24 in the axial direction along the axis X3 of the handle shaft 24.
[0099] The outer ring 133b of the fourth bearing 133 and the outer ring 134b of the fifth bearing 134 are in contact with the inner circumferential surface 150b1 of the handle 25 (the inner circumferential surface 150b1 of the large-diameter bore 150b). The outer ring 133b of the fourth bearing 133 abuts against the fourth annular surface 150b2 of the handle 25 (the fourth annular surface 150b2 of the second handle body 148) along the axial direction of the axis X3 of the handle shaft 24.
[0100] like Figure 7B As shown, the second spacer 135 is disposed between the inner ring 133a of the fourth bearing 133 and the inner ring 134a of the fifth bearing 134. For example, the second spacer 135 is formed in an annular shape. The second spacer 135 is disposed on the outer peripheral surface 145b1 (outer peripheral surface 145b1 of the small diameter portion 145b) of the handle shaft 24 between the inner ring 133a of the fourth bearing 133 and the inner ring 134a of the fifth bearing 134 in the axial direction.
[0101] With the second spacer 135 in contact with the inner ring 133a of the fourth bearing 133 and the inner ring 134a of the fifth bearing 134, the axial length of the inner ring 133a of the fourth bearing 133, the inner ring 134a of the fifth bearing 134, and the second spacer 135 is longer than the axial length of the small-diameter portion 145b of the assembly portion 145. The axial length of the small-diameter portion 145b of the assembly portion 145 can also be interpreted as the axial length from the third annular surface 145a1 of the assembly portion 145 to the end of the small-diameter portion 145b of the assembly portion 145.
[0102] With this structure, when the inner ring 133a of the fourth bearing 133, the inner ring 134a of the fifth bearing 134, and the second spacer 135 are disposed on the outer peripheral surface 145b1 of the small diameter portion 145b of the assembly portion 145, the inner ring 134a of the fifth bearing 134 protrudes slightly from the end of the small diameter portion 145b of the assembly portion 145 in the axial direction along the axis X3 of the handle shaft 24.
[0103] The second positioning member 137 positions the inner ring 133a of the fourth bearing 133, the inner ring 134a of the fifth bearing 134, and the second spacer 135 axially relative to the handle shaft 24. The second positioning member 137 positions the inner ring 134a of the fifth bearing 134 relative to the third annular surface 145a1 at a predetermined position. The second positioning member 137 is mounted on the assembly portion 145 of the handle shaft 24. For example, the second positioning member 137 is mounted on the small-diameter portion 145b of the assembly portion 145. Here, the inner ring 134a of the fifth bearing 134 protrudes slightly from the end of the small-diameter portion 145b of the assembly portion 145 along the axial direction of the handle shaft 24's axis X3, so the second positioning member 137 pushes the inner ring 134a of the fifth bearing 134 towards the third annular surface 145a1.
[0104] like Figure 7B As shown, the second positioning member 137 has a main body 137a and a protruding edge 137b. The structure of the second positioning member 137 is substantially the same as that of the first positioning member 37. By screwing the external thread of the main body 137a into the internal thread 145b2 of the small diameter portion 145b, the protruding edge 137b restricts the movement of the inner ring 134a of the fifth bearing 134 in the direction in which the inner ring 134a of the fifth bearing 134 leaves the third annular surface 145a1. Thus, the inner ring 133a of the fourth bearing 133, the inner ring 134a of the fifth bearing 134, and the second spacer 135 are positioned on the handle shaft 24 axially along the axis X3 of the handle shaft 24.
[0105] like Figure 7A As shown, the second limiting member 139 is fitted to the handle 25. For example, the second limiting member 139 is fitted to the second handle body 148 of the handle 25. More specifically, as... Figure 7B As shown, the second limiting member 139 has a hollow cylindrical portion 139a at its end and an externally threaded portion 139b at its base. The externally threaded portion 139b is screwed into the internally threaded portion 150b3 of the second cylindrical portion 150 (large-diameter bore portion 150b). Thus, the end of the hollow cylindrical portion 139a of the second limiting member 139 abuts against the outer ring 134b of the fifth bearing 134. In this state, the second limiting member 139 restricts the movement of the outer ring 134b of the fifth bearing 134 in the direction away from the outer ring 133b of the fourth bearing 133 (along the axial direction of the axis X3 of the handle shaft 24). For example, the second limiting member 139 restricts the movement of the outer ring 134b of the fifth bearing 134 in the direction away from the fourth annular surface 150b2 of the handle handle 25 (second handle body 148).
[0106] Thus, the second restriction member 139 restricts the movement of the outer ring 134b of the fifth bearing 134 in a direction in which the outer ring 134b of the fifth bearing 134 is separated from the outer ring 133b of the fourth bearing 133, whereby the axial interval of the outer ring 133b of the fourth bearing 133 and the outer ring 134b of the fifth bearing 134 becomes smaller than the axial interval of the inner ring 133a of the fourth bearing 133 and the inner ring 134a of the fifth bearing 134. That is, the gap between the outer ring 133b of the fourth bearing 133 and the outer ring 134b of the fifth bearing 134 becomes small. Thus, the fourth bearing 133 and the fifth bearing 134 are pre-pressed, and the movement between the inner and outer rings is suppressed.
[0107] The second support structure 109 having the above-described structure is assembled as follows. First, the handle knob 25 is assembled in a state of being fitted to the outer periphery of the handle shaft 24, and the fourth bearing 133, the second spacer 135, and the fifth bearing 134 are disposed between the outer peripheral surface 145bl of the fitting portion 145 (the small-diameter portion 145b) of the handle shaft 24 and the inner peripheral surface 150bl of the handle knob 25 (the second cylindrical portion 150). In this state, the second positioning member 137 is fitted to the fitting portion 145 (the small-diameter portion 145b) of the handle shaft 24. Thus, the fourth bearing 133, the second spacer 135, and the fifth bearing 134 are positioned to the handle shaft 24 by the second positioning member 137.
[0108] Next, the second restriction member 139 is screwed into the large-diameter hole portion 150b of the handle knob 25. The second restriction member 139 restricts the movement of the outer ring 134b of the fifth bearing 134 in a direction in which the outer ring 134b of the fifth bearing 134 is separated from the outer ring 133b of the fourth bearing 133. Thus, the handle shaft 24 rotatably supports the handle knob 25.
[0109] In the second support structure 109 of the double-bearing yarn winding wheel 1 described above, the movement of the outer ring 134b of the fifth bearing 134 in a direction in which the outer ring 134b of the fifth bearing 134 is separated from the outer ring 133b of the fourth bearing 133 is restricted by the second restriction member 139, whereby the inner clearance of the fourth bearing 133 and the fifth bearing 134 becomes small. Thus, the wobble of the handle shaft 24 with respect to the handle knob 25 can be suppressed. In addition, in this case, the sliding resistance of the handle shaft 24 can be reduced, so the handle knob 25 can be smoothly rotated with respect to the handle shaft 24.
[0110] <Other Embodiments>
[0111] The above describes one embodiment of the present application, but the present application is not limited to the above-described embodiment, and various changes can be made within the scope of the gist of the present application. For example, the expression "abut" in the present embodiment means not only direct contact but also, for example, as in the following embodiment, contact with another member interposed therebetween.
[0112] (A1) As shown in Figs. 1 and 2, the first support structure 9 and the second support structure 109 can further include a first elastic member 61 and a second elastic member 62, respectively. Figure 8A and Figure 8B As shown in Figs. 1 and 2, the first support structure 9 and the second support structure 109 can further include a first elastic member 61 and a second elastic member 62, respectively.
[0113] For example, as shown in Figs. 1 and 2, in the first support structure 9, the first elastic member 61 is disposed between the outer ring 34b of the second bearing 34 and the winding reel body 3 (the second side plate 19) in the axial direction along the axis X2 of the handle shaft 31. Also, as shown in Figs. 1 and 2, in the second support structure 109, the second elastic member 62 is disposed between the outer ring 133b of the fourth bearing 133 and the handle grip 25 (the second grip body 148) in the axial direction along the axis X3 of the handle grip 24. Figure 8A Figure 8B For example, as shown in Figs. 1 and 2, in the first support structure 9, the first elastic member 61 is disposed between the outer ring 34b of the second bearing 34 and the winding reel body 3 (the second side plate 19) in the axial direction along the axis X2 of the handle shaft 31. Also, as shown in Figs. 1 and 2, in the second support structure 109, the second elastic member 62 is disposed between the outer ring 133b of the fourth bearing 133 and the handle grip 25 (the second grip body 148) in the axial direction along the axis X3 of the handle grip 24.
[0114] For example, the first elastic member 61 and the second elastic member 62 are O-rings. The first elastic member 61 is disposed between the outer ring 34b of the second bearing 34 and the second annular surface 47a2 of the winding reel body 3 in the axial direction along the axis X2 of the handle shaft 31. The second elastic member 62 is disposed between the outer ring 133b of the fourth bearing 133 and the fourth annular surface 150b2 of the handle grip 25 in the axial direction along the axis X3 of the handle grip 24.
[0115] By thus disposing the first elastic member 61 and the second elastic member 62, it is possible to easily adjust the pre-press of each bearing (the first and second bearings 33, 34 / the fourth and fifth bearings 133, 134). Also, when vibration is input from the outside to each bearing (the first and second bearings 33, 34 / the fourth and fifth bearings 133, 134), it is possible to absorb the vibration with the first and second elastic members 61, 62.
[0116] (A2) Instead of the first elastic member 61 and / or the second elastic member 62 of (A1) described above, a spacer can be disposed. In this case, the spacer is preferably a retainer or a washer member. Also, the first elastic member 61 and / or the second elastic member 62 of (A1) and the spacer can be used in combination.
[0117] Further, in the case of using the first elastic member 61 and / or the spacer, the outer ring 34b of the second bearing 34 abuts against the second annular surface 47a2 of the winding reel body 3 via the first elastic member 61 and / or the spacer. Also, in the case of using the second elastic member 62 and / or the spacer, the outer ring 133b of the fourth bearing 133 abuts against the fourth annular surface 150b2 in the axial direction via the second elastic member 62 and / or the spacer.
[0118] (A3) In the foregoing first and second embodiments, examples in which the first support structure 9 and / or the second support structure 109 are applied to the double-bearing winding wheel 1 are shown, but a support structure corresponding to the first support structure 9 and / or the second support structure 109 can also be applied to other types of winding wheels.
