Dual bearing spooling wheel

Abstract

The present application provides a double bearing reel capable of alleviating the restriction associated with the design of a clutch cam. The double bearing reel (1) is provided with a reel body (3), a spool (5), a handle (7), a clutch operating member (9), and a clutch control mechanism (17). The clutch operating member moves relative to the reel body between a first position, a second position, and a third position located between the first position and the second position. The clutch control mechanism has a clutch pawl (47) and a clutch cam (49). The clutch cam is pushed by the clutch pawl, and thus rotates only in a predetermined first direction. In the case where the clutch operating member moves from the first position to the second position, a first pushing portion (63a) pushes a first pushed portion (69a). In the case where the clutch operating member moves from the third position to the second position, a second pushing portion (63b) pushes a second pushed portion (69b).

Description

Technical Field

[0001] This invention relates to a double-bearing winding reel. Background Technology

[0002] Patent Document 1's double-bearing winding reel includes a clutch mechanism that transmits and cuts off the rotational force of the handle relative to the drum, and a clutch control mechanism that switches the clutch mechanism to a transmission state and a cut-off state by operating a clutch operating component.

[0003] In this structure, the clutch operating component moves from position 1 to position 2, thereby rotating the clutch cam and causing the clutch control mechanism to alternately switch the clutch mechanism between a transmitting state and a disengaged state. In this case, the clutch operating component is positioned in position 1 in both the transmitting state and the disengaged state of the clutch mechanism.

[0004] The double-bearing winding reel in Patent Document 2, like the double-bearing winding reel in Patent Document 1, includes a clutch mechanism and a clutch control mechanism. The clutch control mechanism includes a clutch pawl and a clutch cam.

[0005] In this structure, the clutch pawl has a pawl tip. When the clutch operating member moves from position 1 to position 2, the pawl tip pushes against the ratchet teeth of the clutch cam. This causes the clutch cam to rotate, and the clutch control mechanism switches the clutch mechanism from a transmitting state to a disengaged state. When the clutch mechanism is in the disengaged state, the clutch operating member is positioned in position 3, between position 1 and position 2.

[0006] When the clutch operating component moves from position 3 to position 2, the tip of the clutch pawl pushes against the first positioning part of the clutch cam. This causes the clutch cam to rotate, and the clutch control mechanism switches the clutch mechanism from the disengaged state to the transmission state. When the clutch mechanism is in the transmission state, the clutch operating component is positioned in position 1.

[0007] Patent Document 1: Japanese Patent No. 6518514.

[0008] Patent Document 2: Japanese Patent No. 6914052.

[0009] In the dual-bearing reel of Patent Document 1, the clutch operating component is positioned in the first position in both the case of the clutch mechanism being in the transmission state and the case of the clutch mechanism being in the disengagement state. Therefore, it is difficult for the angler to determine the state of the clutch mechanism by observing the position of the clutch operating component. Furthermore, when the clutch operating component is positioned in the first position in the case of the clutch mechanism being in the disengagement state, the space available for the angler to make thumb movements is narrowed.

[0010] In the double-bearing winding reel of Patent Document 2, when the clutch mechanism is in the disengaged state, the clutch operating component is positioned in a third position between the first and second positions, thus solving the problem mentioned in Patent Document 1. However, in the double-bearing winding reel of Patent Document 2, it is necessary to push the ratchet teeth of the clutch cam and the first positioning part of the clutch cam with only one claw tip. Therefore, in order to increase the number of ratchet teeth and the first positioning part arranged on the outer periphery of the clutch cam, the diameter of the clutch cam needs to be increased. Alternatively, it is difficult to reduce the diameter of the clutch cam without changing the number of ratchet teeth and the first positioning part. Summary of the Invention

[0011] The purpose of this invention is to provide a dual-bearing winding wheel that can alleviate the limitations associated with the design of a clutch cam.

[0012] One embodiment of the present invention provides a double-bearing winding reel comprising a winding reel body, a drum, a handle, a clutch mechanism, a clutch operating component, and a clutch control mechanism. The drum is configured to rotate relative to the winding reel body. The handle is configured to rotate relative to the winding reel body. The clutch mechanism is disposed between the drum and the handle.

[0013] The clutch operating component is configured to move relative to the winding wheel body. The clutch operating component is movable relative to the winding wheel body between a first position, a second position, and a third position between the first and second positions.

[0014] The clutch control mechanism has a clutch pawl and a clutch cam. The clutch pawl is located on the clutch operating component. The clutch cam is pushed by the clutch pawl, thereby rotating only in a predetermined first direction. The clutch control mechanism controls the clutch mechanism by the rotation of the clutch cam.

[0015] The clutch pawl has a first pressing portion and a second pressing portion different from the first pressing portion. The clutch cam has a first pressed portion and a second pressed portion. The first pressed portion is pressed by the first pressing portion. The second pressed portion is disposed on a side further in a second direction than the first pressed portion. The second direction is the opposite direction to the first direction. The second pressed portion is pressed by the second pressing portion.

[0016] When the clutch operating member moves from the first position to the second position, the first pushing part pushes the first pushed part. When the clutch operating member moves from the third position to the second position, the second pushing part pushes the second pushed part.

[0017] In this dual-bearing winding reel, corresponding to the position of the clutch operating component, two pushing parts (a first pushing part and a second pushing part) individually push two pushed parts (a first pushed part and a second pushed part). Therefore, compared to the prior art, the number of the first pushed parts can be increased. Alternatively, the clutch cam diameter can be reduced without changing the number of the first pushed parts. In other words, according to this dual-bearing winding reel, compared to the prior art, the limitations related to the design of the clutch cam can be alleviated.

[0018] In another embodiment of the invention, the double-bearing winding wheel preferably uses a clutch control mechanism to switch the clutch mechanism to a first state and a second state different from the first state by rotating the clutch cam.

[0019] In another embodiment of the present invention, the double-bearing winding reel is preferably configured as follows: The first state is a transmission state in which the rotational force of the handle is transmitted to the drum. The second state is a cutting-off state in which the transmission of the rotational force of the handle relative to the drum is cut off.

[0020] In another embodiment of the invention, the double-bearing winding wheel is preferably such that, in the axial direction about the rotation center axis of the clutch cam, the second pushed portion is at least partially offset from the first pushed portion.

[0021] In another embodiment of the invention, the dual-bearing winding wheel is preferably provided that the clutch pawl also has a wall portion that restricts the engagement of the second pressing portion relative to the first pressed portion.

[0022] In another embodiment of the present invention, the dual-bearing winding wheel is preferably provided that the clutch pawl further has a positioning portion for positioning the clutch operating component relative to the winding wheel body at a third position.

[0023] In another embodiment of the present invention, the double-bearing winding wheel is preferably a separate component having a claw portion having a first pressing portion and a second pressing portion and a positioning portion.

[0024] In another embodiment of the invention, the dual-bearing winding reel is preferably configured as follows: The claw portion is formed of resin. The positioning portion is formed of metal.

[0025] Another embodiment of the present invention, the double-bearing winding reel, is preferably configured as follows: The clutch operating component has a support plate. The support plate rotatably supports the clutch cam. The support plate is disposed between the winding reel body and the clutch cam. The clutch cam has an annular portion and a push-pressing pawl. The push-pressing pawl protrudes from the outer peripheral surface of the annular portion. The push-pressing pawl constitutes a first push-pressing portion and a second push-pressing portion. A gap is provided between the support plate and the push-pressing pawl.

[0026] Another embodiment of the present invention, the double-bearing winding reel, is preferably configured as follows: The clutch operating component has a support plate. The support plate rotatably supports the clutch cam. The support plate is disposed between the winding reel body and the clutch cam. The clutch pawl has a positioning portion and a cover portion. The positioning portion positions the clutch operating component relative to the winding reel body at a third position. The cover portion is disposed on the positioning portion. When the clutch operating component is in the third position relative to the winding reel body, and the clutch pawl and support plate are viewed from the axially outer side, at least a portion of the cover portion overlaps with the support plate.

[0027] Another embodiment of the present invention, the double-bearing winding reel, is preferably configured as follows: The winding reel body has a shaft portion. The clutch pawl also has a positioning portion. The positioning portion positions the clutch operating component relative to the winding reel body at a third position. The positioning portion engages with the shaft portion.

[0028] Another embodiment of the present invention, the double-bearing winding reel, is preferably constructed as follows: The winding reel body has a recess. The clutch pawl also has a positioning portion. The positioning portion positions the clutch operating component relative to the winding reel body at a third position. The positioning portion has a main body, an engaging portion, and a force-applying component. The engaging portion is disposed on the main body. The engaging portion engages with the recess. The force-applying component is disposed between the main body and the engaging portion. The force-applying component applies force to the engaging portion.

[0029] In another aspect of the invention, in a double-bearing winding reel, preferably, the clutch pawl has a first clutch pawl including a first pressing portion and a second clutch pawl including a second pressing portion.

[0050] The double-bearing winding wheel 1 of the present invention is as follows: Figure 1As shown, it includes a winding reel body 3, a drum 5, a handle 7, and a clutch operating component 9. Figure 2 As shown, the double-bearing winding reel 1 also includes a drum shaft 11, a planetary gear 13, a clutch mechanism 15, and a clutch control mechanism 17. Figure 3A As shown, the double-bearing winding wheel 1 also has a clutch return mechanism 19.

[0051] In this embodiment, such as Figure 2 As shown, the drum shaft 11 has a drum axis X1. The clutch cam 49 of the clutch control mechanism 17, described later, has a rotation center axis X2. The drum axis X1 and the rotation center axis X2 of the clutch cam 49 are concentric.

[0052] The axial direction includes the direction in which the drum shaft X1 extends, the direction along the drum shaft X1, the direction in which the rotation center axis X2 of the clutch cam 49 extends, or the direction along the rotation center axis X2 of the clutch cam 49. The radial direction includes the direction away from the drum shaft X1 and the direction away from the rotation center axis X2 of the clutch cam 49.

[0053] The circumferential and rotational directions include the direction about the drum axis X1 and the direction about the rotational center axis X2 of the clutch cam 49. In this embodiment, the direction of rotation of the clutch cam 49 about the rotational center axis X2 is denoted as the first rotational direction R1. The rotational direction opposite to the first rotational direction R1 is denoted as the second rotational direction R2.

[0054] like Figure 1 As shown, the winding wheel body 3 includes a frame 21, a first side cover 23, and a second side cover 25. The winding wheel body 3 also includes a display section 27 mounted on the frame 21.

[0055] like Figure 2 As shown, frame 21 has a first side plate 29, a second side plate 31, and multiple connecting parts 33. The first side plate 29 is disposed on the handle 7 side. The first side plate 29 has a side plate body 35 and a mechanism mounting plate 37.

[0056] The mechanism mounting plate 37 is disposed between the side plate body 35 and the first side cover 23. For example, the mechanism mounting plate 37 has a main body portion 37a and a cylindrical portion 37b. The main body portion 37a is mounted to the side plate body 35. The clutch operating component 9 and the clutch control mechanism 17 are disposed in the main body portion 37a. The cylindrical portion 37b is integrally formed with the main body portion 37a. The planetary gear 13 and the drum shaft 11 are inserted into the inner periphery of the cylindrical portion 37b.

[0057] like Figure 3AAs shown, the winding reel body 3 also has a shaft portion 28. The shaft portion 28 is disposed on the mechanism mounting plate 37. The shaft portion 28 and the mechanism mounting plate 37 are integrally formed. The arm portion 59, described later, abuts against the shaft portion 28. In this embodiment, an interference member 28a is disposed on the shaft portion 28. The arm portion 59 abuts against the shaft portion 28 via the interference member 28a.

[0058] like Figure 2 As shown, the second side plate 31 is axially spaced from the first side plate 29. A spool 5 is disposed between the first side plate 29 and the second side plate 31. Multiple connecting members 33 connect the first side plate 29 and the second side plate 31. The front connecting member 33 is cylindrical. A motor 34 is housed inside the front connecting member 33a. A rod mounting foot for assembling a fishing rod is integrally formed with the lower connecting member 33b. A first side cover 23 covers the first side plate 29. A second side cover 25 covers the second side plate 31.

[0059] like Figure 1 As shown, the handle 7 is configured to rotate relative to the winding wheel body 3. For example, the handle 7 is provided on the first side cover 23 side. The handle 7 is rotatably supported relative to the winding wheel body 3. The handle 7 is connected to a drive shaft (not shown in the figure). The rotational force of the handle 7 is transmitted to the drive shaft.

[0060] like Figure 2 As shown, the spool 5 is configured to rotate relative to the winding wheel body 3. For example, the spool 5 is mounted to the spool shaft 11 in a manner that allows it to rotate integrally with the spool shaft 11. The spool 5 is rotatably supported on the winding wheel body 3 via the spool shaft 11.

[0061] The spool 11 is rotatably supported relative to the winding reel body 3. For example, the spool 11 is rotatably supported relative to the first side plate 29 (side plate body 35). The spool 11 is rotatably supported relative to the shaft support portion 32 provided at the second side plate 31. The shaft support portion 32 is fitted to the second side plate 31. The spool 11 is inserted through the inner circumference of the planetary gear 13.

[0062] like Figure 2 As shown, the planetary gear 13 is disposed on the outer periphery of the drum shaft 11 in such a way that it can move axially relative to the drum shaft 11. The planetary gear 13 moves axially relative to the drum shaft 11 by means of a clutch control mechanism 17.

[0063] The planetary gear 13 rotates integrally with and relative to the drum shaft 11 via the clutch mechanism 15. The planetary gear 13 is disposed on the outer circumference of the drum shaft 11.

[0064] For example, when the clutch mechanism 15 is in the clutch engaged state (an example of the first state), as described later, the planetary gear 13 rotates integrally with the drum shaft 11. When the clutch mechanism 15 is in the clutch disengaged state (an example of the second state), as described later, the planetary gear 13 rotates relative to the drum shaft 11. Figure 2 The image shows an example of the clutch mechanism 15 being in the clutch engaged state.

[0065] The rotational force of the handle 7 or the rotational force of the motor 34 is transmitted to the planetary gear 13 via the drum drive mechanism 14. For example, the drum drive mechanism 14 has a drive shaft connected to the handle 7, a drive gear connected to the drive shaft, a planetary gear mechanism connected to the drive gear and the output shaft of the motor 34, and a rotational transmission mechanism connected to the planetary gear mechanism. The rotational force is transmitted from the rotational transmission mechanism to the planetary gear 13.

[0066] like Figure 2 As shown, a clutch mechanism 15 is disposed between the handle 7 and the drum 5. The clutch mechanism 15 transmits and disconnects the rotational force of the handle 7 relative to the drum 5. The clutch mechanism 15 is configured to switch between a clutch engaged state and a clutch disengaged state, which is different from the clutch engaged state. The clutch engaged state is the transmission state in which the rotational force of the handle 7 is transmitted to the drum 5. The clutch disengaged state is the disengagement state in which the transmission of the rotational force of the handle 7 relative to the drum 5 is cut off.

[0067] like Figure 2 As shown, the clutch mechanism 15 has a pin component 15a and an engagement recess 15b. The pin component 15a is disposed on the drum shaft 11. Both ends of the pin component 15a protrude from the outer peripheral surface of the drum shaft 11. The engagement recess 15b is disposed on the planetary gear 13. The state in which the pin component 15a is engaged with the engagement recess 15b is the clutch engaged state. The state in which the pin component 15a is disengaged from the engagement recess 15b is the clutch disengaged state.

[0068] like Figures 3A-3D As shown, the clutch operating component 9 is used to operate the clutch control mechanism 17. The clutch operating component 9 is configured to move relative to the winding wheel body 3. For example, the clutch operating component 9... Figure 3A The first position indicated in the middle Figure 3B The second position indicated in the middle Figure 3C The third position, as indicated in the diagram, moves relative to the winding wheel body 3. The third position is located between the first and second positions.

[0069] like Figures 3A-3D As shown, the clutch operating component 9 includes an operating part 39, a connecting arm 41, and a support plate 43. The operating part 39 is the part that is pushed by the angler (see reference). Figure 1The operating part 39 is fitted to the connecting arm 41. The connecting arm 41 is integrally formed with the support plate 43. The connecting arm 41 extends from the support plate 43 and passes through the hole 35a in the first side plate 29 (side plate body 35). The operating part 39 is fitted to the end portion of the connecting arm 41.

[0070] like Figure 2 As shown, the support plate 43 is disposed between the winding wheel body 3 and the clutch control mechanism 17. For example, the support plate 43 is axially disposed between the mechanism mounting plate 37 and the clutch cam 49 of the clutch control mechanism 17, which will be described later.

[0071] like Figures 3A-3D As shown, the support plate 43 is rotatably mounted relative to the winding wheel body 3. For example, the support plate 43 is rotatably mounted relative to the mechanism mounting plate 37. The support plate 43 rotatably supports the clutch cam 49.

[0072] like Figure 3A As shown, a support shaft 43a is disposed on a support plate 43. The support shaft 43a provides swingable support for the clutch pawl 47 of the clutch control mechanism 17, which will be described later. The support shaft 43a is disposed on the support plate 43 in an axially extending manner. The support shaft 43a may be integrally formed with the support plate 43 or separately formed from the support plate 43.

[0073] The clutch operating component 9, having the above-described structure, is forced from the second position to the first position by the first torsion spring 45. For example, as... Figures 3A-3D As shown, the first spring arm 45a of the first torsion spring 45 engages with the support plate 43. The second spring arm 45b of the first torsion spring 45 engages with the mechanism assembly plate 37.

[0074] In this structure, such as Figure 3A and Figure 3B As shown, when the clutch operating component 9 moves from the first position to the second position, the support plate 43 rotates relative to the mechanism mounting plate 37, and the first torsion spring 45 twists. As a result, the first torsion spring 45 applies force to the clutch operating component 9 from the second position to the first position by means of the restoring force.

[0075] Clutch control mechanism 17 controls Figure 2 The clutch mechanism 15 is shown in the diagram. For example, in the clutch control mechanism 17, the clutch mechanism 15 is controlled by the rotation of the clutch cam 49. Specifically, in the clutch control mechanism 17, the clutch mechanism 15 is switched between a clutch engaged state and a clutch disengaged state by the rotation of the clutch cam 49. Figure 2 As shown, the clutch control mechanism 17 is disposed between the first side cover 23 and the first side plate 29.

[0076] like Figures 3A-3DAs shown, the clutch control mechanism 17 includes a clutch pawl 47 and a clutch cam 49. The clutch control mechanism 17 also includes a yoke support member 51, a clutch yoke 53, a planetary gear 13, and a coil spring 55 (see reference). Figure 2 and Figure 5 The clutch pawl 47 is pivotally mounted relative to the clutch operating member 9. For example, the clutch pawl 47 is pivotally mounted relative to the support plate 43.

[0077] like Figure 4 As shown, the clutch pawl 47 has a pawl portion 57 and an arm portion 59 (an example of a positioning portion). The pawl portion 57 has a main body portion 61 and a pressing portion 63. The main body portion 61 has a mounting hole 61a. The mounting hole 61a is for mounting the support shaft 43a of the support plate 43.

[0078] The pressing part 63 is integrally formed with the main body part 61. For example, as Figures 3A-3D As shown, with the main body 61 mounted on the support shaft 43a of the support plate 43, the pushing part 63 is configured to face the outer periphery of the clutch cam 49.

[0079] like Figure 4 As shown, the pressing part 63 includes a first pressing part 63a, a second pressing part 63b, and a limiting wall 63c (an example of a wall). The first pressing part 63a is provided at the pressing part 63 on the side of the first rotation direction R1. The second pressing part 63b is different from the first pressing part 63a. The second pressing part 63b is provided at the pressing part 63 on the side of the second rotation direction R2. The second pressing part 63b is arranged at a distance from the first pressing part 63a in the second rotation direction R2. The axial length of the second pressing part 63b is shorter than the axial length of the first pressing part 63a.

[0080] A limiting wall 63c is disposed between the first pressing part 63a and the second pressing part 63b. The limiting wall 63c abuts against the radially outer surface 69f of the first pressed part 69a of the clutch cam 49, which will be described later. As a result, the second pressing part 63b passes through the first pressed part 69a without engaging with the first pressed part 69a. That is, the limiting wall 63c restricts the engagement of the second pressing part 63b with respect to the first pressed part 69a.

[0081] like Figure 4 As shown, the arm portion 59 is disposed on the claw portion 57. For example, the arm portion 59 and the claw portion 57 are integrally formed. Figure 3C As shown, the arm 59 engages with the shaft 28 of the winding wheel body 3. For example, the end of the arm 59 abuts against the shaft 28 of the mechanism mounting plate 37. Specifically, the end of the arm 59 is formed in a hook shape. The end of the arm 59 is engaged with the shaft 28 via the interference member 28a. Thus, the arm 59 positions the clutch operating member 9 relative to the winding wheel body 3 in a third position.

[0082] The clutch pawl 47 having the above-described structure is as follows Figures 3A-3D As shown, a force is applied to the clutch cam 49 by means of a second torsion spring 65. For example, the coil portion 65a of the second torsion spring 65 is disposed on the support shaft 43a of the support plate 43. The coil portion 65a is prevented from disengaging by means of an anti-disengagement component not shown in the figure.

[0083] The third spring arm 65b of the second torsion spring 65 engages with the support plate 43. The fourth spring arm of the second torsion spring 65 engages with the hole 63d of the pressing part 63 (see reference). Figure 4 Engagement. With the aid of this structure, the second torsion spring 65 applies force to the clutch cam 49 through the pushing part 63 of the clutch pawl 47.

[0084] like Figures 3A-3D As shown, the clutch cam 49 is rotatably configured relative to the winding wheel body 3. For example, the clutch cam 49 is rotatably configured relative to the mechanism mounting plate 37 of the winding wheel body 3. The clutch cam 49 is pushed by the clutch pawl 47, thereby rotating only in the first rotational direction R1.

[0085] like Figure 5 As shown, the clutch cam 49 has an annular portion 67, multiple ratchet teeth 69 (push-down pawls), and multiple cam portions 71. Figure 5 The reference numerals indicating ratchet tooth 69 and cam portion 71 are used to indicate only one component.

[0086] The annular portion 67 is formed in an annular shape. For example... Figure 6 As shown, the annular portion 67 is disposed on the support plate 43. The annular portion 67 is disposed on the cylindrical portion 37b of the mechanism mounting plate 37 (see reference). Figure 2 ) on the radial outer side.

[0087] like Figure 5 As shown, a plurality of ratchet teeth 69 are disposed on the outer periphery of the annular portion 67. For example, the plurality of ratchet teeth 69 are arranged at intervals from each other in the circumferential direction. The plurality of ratchet teeth 69 protrude radially outward from the outer peripheral surface 67a of the annular portion 67. The plurality of ratchet teeth 69 are integrally formed with the outer peripheral surface 67a of the annular portion 67. In this embodiment, the plurality of ratchet teeth 69 includes eight ratchet teeth 69.

[0088] like Figure 6 and Figure 7 As shown, each ratchet tooth 69 has a first pushed portion 69a and a second pushed portion 69b. Each ratchet tooth 69 also has a first inclined surface 69c, a top surface 69d, and a second inclined surface 69e.

[0089] The first pressed portion 69a is pressed by the first pressing portion 63a. The first pressed portion 69a is provided at the end of each ratchet tooth 69 on the upstream side of the first rotation direction R1. The first pressed portion 69a includes a radially outer surface 69f.

[0090] The second pressed portion 69b is pressed by the second pressed portion 63b. The second pressed portion 69b is arranged on the side of the first rotation direction R1 compared to the first pressed portion 69a. For example, at the ratchet teeth 69 that are adjacent to each other in the circumferential direction, the second pressed portion 69b is arranged on the side of the second rotation direction R2 compared to the first pressed portion 69a.

[0091] The second pressed portion 69b is provided radially outward from the outer peripheral surface 67a of the annular portion 67. The second pressed portion 69b is provided on the end face of the ratchet tooth 69. The second pressed portion 69b is formed in a concave shape on the end face of the ratchet tooth 69.

[0092] like Figure 6 As shown, the second pushed portion 69b is at least partially offset from the first pushed portion 69a in the axial direction. For example, the range in which the second pushed portion 69b is provided in the axial direction is different from the range in which the first pushed portion 69a is provided in the axial direction. The axial length of the second pushed portion 69b is shorter than the axial length of the first pushed portion 69a.

[0093] like Figure 6 and Figure 7 As shown, the first inclined surface 69c extends from the outer peripheral surface 67a of the annular portion 67 towards the second pushed portion 69b and connects with the second pushed portion 69b. The top surface 69d is provided radially outward from the outer peripheral surface 67a of the annular portion 67. The top surface 69d forms the end face of the ratchet tooth 69.

[0094] The top surface 69d extends circumferentially between the second pressed portion 69b and the second inclined surface 69e. The top surface 69d is connected to the second pressed portion 69b and the second inclined surface 69e. The second inclined surface 69e extends from the top surface 69d toward the radially outer surface 69f of the first pressed portion 69a and is connected to the radially outer surface 69f of the first pressed portion 69a.

[0095] like Figure 7 As shown, the distance from the radially outer surface 69f of the first pressed portion 69a to the rotation center axis X2 is smaller than the distance from the top surface 69d to the rotation center axis X2. The distance from the radially outer surface 69f of the first pressed portion 69a to the rotation center axis X2 is larger than the distance from the outer peripheral surface 67a of the annular portion 67 to the rotation center axis X2.

[0096] like Figure 5As shown, a plurality of cam portions 71 are disposed on the annular portion 67. For example, the plurality of cam portions 71 are arranged at intervals from each other in the circumferential direction. The plurality of cam portions 71 each protrude from the annular portion 67 in the axial direction. The plurality of cam portions 71 are each integrally formed with the annular portion 67. In this embodiment, the plurality of cam portions 71 includes eight cam portions 71.

[0097] like Figure 6 and Figure 7 As shown, each cam portion 71 has a positioning recess 71a, a third inclined surface 71b, a fourth inclined surface 71c, and a vertical surface 71d. The positioning recess 71a is provided on the top of each cam portion 71. The positioning recess 71a is formed in a concave shape on the top of each cam portion 71. The positioning recess 71a positions the clutch yoke 53 in the clutch disengaged state.

[0098] The third inclined surface 71b extends from the front surface 67b of the annular portion 67 toward the positioning recess 71a and connects with the positioning recess 71a. The fourth inclined surface 71c extends from the positioning recess 71a toward the upper end of the erecting surface 71d and connects with the upper end of the erecting surface 71d. The erecting surface 71d extends from the fourth inclined surface 71c toward the front surface 67b of the annular portion 67 and connects with the front surface 67b of the annular portion 67.

[0099] like Figure 6 As shown, the distance from the upper end of the upright surface 71d to the front surface 67b of the annular portion 67 is smaller than the distance from the connection between the positioning recess 71a and the fourth inclined surface 71c to the front surface 67b of the annular portion 67.

[0100] like Figures 3A-3D As shown, the yoke support component 51 is assembled to the winding wheel body 3. For example, the yoke support component 51 is fixed to the mechanism assembly plate 37.

[0101] like Figure 5 As shown, the yoke support member 51 has a mounting portion 51a and a pair of guide shafts 51b. The mounting portion 51a is formed in a ring shape. The mounting portion 51a is fixed to the mechanism mounting plate 37. The pair of guide shafts 51b are each formed in a rod shape. The pair of guide shafts 51b are disposed on the mounting portion 51a. With the mounting portion 51a fixed to the mechanism mounting plate 37, the pair of guide shafts 51b extend axially.

[0102] like Figure 5 As shown, the clutch yoke 53 has a yoke body 53a, a pair of guide holes 53b, a gear engagement portion 53c, and a cam engagement portion 53d. The yoke body 53a is substantially longer in one direction.

[0103] A pair of guide holes 53b are provided in the yoke body 53a. The pair of guide holes 53b pass through the yoke body 53a. A pair of guide shafts 51b are each inserted into the pair of guide holes 53b.

[0104] Thus, the clutch yoke 53 is axially guided along a pair of guide shafts 51b. For example, when the clutch cam 49 rotates in the first rotation direction R1, the clutch yoke 53 moves axially away from the drum 5 and axially close to the drum 5.

[0105] A gear engagement portion 53c is provided at the center of the yoke body 53a. For example, the gear engagement portion 53c is formed as a semi-circle. The gear engagement portion 53c engages with the annular recess 13a of the planetary gear 13. As a result, the clutch yoke 53 and the planetary gear 13 move together axially.

[0106] Cam engagement portions 53d are provided at both ends of the yoke body 53a. Cam engagement portions 53d engage with the cam portion 71 of the clutch cam 49. For example, as... Figure 3A and Figure 3D As shown, when the clutch mechanism 15 is in the clutch engaged state, the cam engagement portion 53d is disposed on the front surface 67b of the annular portion 67 between adjacent cam portions 71 in the circumferential direction. Figure 3B and Figure 3C As shown, when the clutch mechanism 15 is in the clutch disengaged state, the cam engagement portion 53d is disposed in the positioning recess 71a of the cam portion 71.

[0107] like Figure 2 As shown, the helical spring 55 is disposed radially outward of the drum shaft 11. The helical spring 55 is axially positioned between the clutch yoke 53 and the first side cover 23. Thus, the helical spring 55 applies an axial force to the clutch yoke 53 towards the drum 5.

[0108] like Figure 3A As shown, the clutch return mechanism 19 includes a return gear 73 and a clutch cam 49. The return gear 73 is connected to the drive shaft 70. The return gear 73 rotates together with the drive shaft 70. For example, as... Figure 8A As shown, when the clutch mechanism 15 is in the clutch disengaged state, as Figure 8B As shown, when the handle 7 rotates in the winding direction M, the return gear 73 rotates. As a result, one of the multiple gear teeth 73a of the return gear 73 pushes one of the multiple ratchet teeth 69 of the clutch cam 49, and the clutch cam 49 rotates in the first rotation direction R1.

[0109] like Figures 3A-3D As shown, the clutch control mechanism 17 operates. Figure 3AAs shown, with the clutch operating component 9 positioned in the first position, the clutch mechanism 15 is in the clutch engaged state. In this state, the cam engagement portion 53d of the clutch yoke 53 is positioned on the front surface 67b of the annular portion 67 between adjacent cam portions 71 in the circumferential direction. The first pressing portion 63a and the second pressing portion 63b of the clutch pawl 47 are positioned between adjacent ratchet teeth 69 in the circumferential direction.

[0110] First, such as Figure 3A and Figure 3B As shown, when the angler pushes the operating part 39 of the clutch operating component 9, and the operating part 39 moves from the first position to the second position, the first pushing part 63a of the clutch pawl 47 pushes the first pushed part 69a of the clutch cam 49. As a result, the clutch cam 49 rotates in the first rotation direction R1.

[0111] As the clutch cam 49 rotates, the cam engagement portion 53d of the clutch yoke 53 rises at the third inclined surface 71b of the cam portion 71 and is positioned in the positioning recess 71a. Thus, the clutch mechanism 15 switches from the clutch engaged state to the clutch disengaged state.

[0112] Here, when the angler removes his fingers from the clutch operating component 9 (operating part 39), such as Figure 3B and Figure 3C As shown, the clutch operating component 9 (operating part 39) moves from the second position to the third position. In this case, the clutch pawl 47 moves along the second rotation direction R2. At this time, the second pressing part 63b of the clutch pawl 47 rises at the first inclined surface 69c of the ratchet tooth 69, and the arm 59 of the clutch pawl 47 abuts against the shaft 28 of the winding wheel body 3 (mechanism mounting plate 37).

[0113] Therefore, the second pressing part 63b of the clutch pawl 47 is disposed on the top surface 69d of the ratchet tooth (see reference). Figure 7 In this state, the cam engagement portion 53d of the clutch yoke 53 is positioned in the positioning recess 71a, and the clutch mechanism 15 is in the clutch disengaged state.

[0114] Next, as Figure 3C and Figure 3D As shown, when the angler pushes the clutch operating component 9 (operating part 39), and the clutch operating component 9 (operating part 39) moves from the third position to the second position, the second pushing part 63b of the clutch pawl 47 pushes the second pushed part 69b of the clutch cam 49. As a result, the clutch cam 49 rotates in the first rotation direction R1. At this time, the arm 59 of the clutch pawl 47 disengages from the shaft 28 of the winding reel body 3 (mechanism mounting plate 37).

[0115] Due to the rotation of the clutch cam 49, the cam engagement portion 53d of the clutch yoke 53 disengages from the positioning recess 71a. Afterwards, the cam engagement portion 53d of the clutch yoke 53 disengages from the fourth inclined surface 71c of the cam portion 71 (see reference). Figure 7 The cam portion 71 descends and is positioned on the front surface 67b of the annular portion 67 between adjacent cam portions 71 in the circumferential direction. This switches the clutch mechanism 15 from the clutch disengaged state to the clutch engaged state.

[0116] Here, when the angler removes his fingers from the clutch operating component 9 (operating part 39), such as Figure 3D and Figure 3A As shown, the clutch operating member 9 (operating part 39) moves from the second position to the first position. In this case, the clutch pawl 47 moves along the second rotational direction R2.

[0117] At this time, the first pressing part 63a and the second pressing part 63b of the clutch pawl 47 move along... Figure 7 The outer surface of the ratchet tooth 69, as indicated in the diagram, moves. For example, the first pressing portion 63a and the second pressing portion 63b of the clutch pawl 47 move along the top surface 69d of the ratchet tooth 69 and descend at the second inclined surface 69e of the ratchet tooth 69.

[0118] When the first pressing portion 63a and the second pressing portion 63b of the clutch pawl 47 reach the radially outer surface 69f of the first pressed portion 69a, the limiting wall 63c of the clutch pawl 47 (see reference) Figure 4 The first pressing part 63a and the second pressing part 63b of the clutch pawl 47 are then contacted on their radially outer surface 69f. Afterwards, the first pressing part 63a and the second pressing part 63b of the clutch pawl 47 are positioned between the circumferentially adjacent ratchet teeth 69. As a result, the clutch operating member 9 (operating part 39) returns to the first position.

[0119] like Figure 8A and Figure 8B As shown, the clutch return mechanism 19 operates. Figure 8A As shown, when the clutch mechanism 15 is in the clutch disengaged state, as... Figure 8B When the angler rotates the handle 7 in the line winding direction M, the return gear 73 rotates.

[0120] As the return gear 73 rotates, the gear teeth 73a of the return gear 73 push against the first pushed portion 69a of the clutch cam 49. Consequently, the clutch cam 49 rotates in the first rotational direction R1, as... Figure 3A As shown, the clutch mechanism 15 switches from the clutch disengaged state to the clutch engaged state. At this time, the operation of the clutch yoke 53 is the same as the operation of the clutch yoke 53 of the clutch control mechanism 17.

[0121] In the double-bearing winding wheel 1 with the above-described structure, corresponding to the position of the clutch operating member 9, the first pushing part 63a and the second pushing part 63b respectively push the first pushed part 69a and the second pushed part 69b. Therefore, compared with the prior art, the number of the first pushed parts 69a can be increased. Alternatively, the clutch cam 49 can be made smaller in diameter without changing the number of the first pushed parts 69a. That is, according to this double-bearing winding wheel 1, compared with the prior art, the limitations related to the design of the clutch cam 49 can be alleviated.

[0122] The above describes one embodiment of the present invention, but the present invention is not limited to the above embodiment and various changes can be made without departing from the spirit of the invention.

[0123] • Variation Example 1

[0124] The clutch cam 49 can also be configured as described below. In Modification 1, as... Figure 9 As shown, the annular portion 67 of the clutch cam 49 has a mounting surface 67c. The mounting surface 67c is mounted on the support plate 43 of the clutch operating member 9. With the mounting surface 67c mounted on the support plate 43, a gap G is provided between the plurality of ratchet teeth 69 of the clutch cam 49 and the support plate 43.

[0125] In this structure, when the clutch cam 49 rotates relative to the support plate 43 in the first rotational direction R1, the mounting surface 67c slides against the support plate 43. In this case, the multiple ratchet teeth 69 do not slide against the support plate 43. Thus, the clutch cam 49 can rotate smoothly in the first rotational direction R1.

[0126] • Variation Example 2

[0127] The clutch pawl 147 can also be configured as described below. In Modification 2, as... Figure 10 As shown, the claw portion 157 and the arm portion 159 are separate components. The claw portion 157 is formed of resin. The arm portion 159 is formed of metal. The arm portion 159 is preferably formed by pressure molding. The arm portion 159 has a mounting portion 159a and an arm body 159b. The mounting portion 159a is mounted on the claw portion 157. The arm body 159b is integrally formed with the mounting portion 159a. In this structure, the arm portion 159 can be appropriately elastically deformed. As a result, the clutch operating component 9 can be appropriately positioned relative to the winding wheel body 3 at a third position.

[0128] • Variation Example 3

[0129] The clutch pawl 247 can also be configured as described below. In Modification 3, such as... Figure 11As shown, the clutch pawl 247 also has a cover 64. The cover 64 is disposed on the arm 59. When the clutch operating member 9 is in the third position relative to the winding wheel body 3, and the clutch pawl 47 and the support plate 43 are viewed from the axial outside, at least a portion of the cover 64 overlaps with the support plate 43. In this structure, the gap between the arm 59 of the clutch pawl 47 and the support plate 43 is covered by the cover 64. Thus, the cover 64 can prevent foreign objects from entering the gap.

[0130] • Variation Example 4

[0131] The winding wheel body 3 and the clutch pawl 347 can also be constructed as described below. In variation 4, such as... Figure 12A As shown, the mechanism mounting plate 37 of the winding wheel body 3 has a recess 37c. As... Figure 12A and Figure 12B As shown, the arm 259 of the clutch pawl 347 has a main body 259a, a shaft component 259b (an example of an engaging part), and a coil spring 259c (an example of a force-applying component).

[0132] A shaft component 259b is disposed on the main body 259a. A coil spring 159c is disposed between the main body 259a and the shaft component 259b. The shaft component 259b engages with the recess 37c. For example, the coil spring 259c is disposed in the hole 259d of the main body 259a. One end of the coil spring 259c abuts against the bottom of the hole 259d. The other end of the coil spring 259c abuts against one end of the shaft component 259b. Thus, the shaft component 259b is subjected to force by the coil spring 259c. The other end of the shaft component 259b engages with the recess 37c.

[0133] In the recess 37c, a engaging wall 37d is formed for engaging the other end of the shaft member 259b. The other end of the shaft member 259b abuts against the engaging wall 37d, thereby positioning the clutch operating member 9 (operating part 39) in the third position. In this structure, even if the angler operates the clutch operating member 9 (operating part 39) from the third position to the first position when it is in the third position, the shaft member 259b will retract into the cavity 259d, thus preventing damage to the arm 259.

[0134] • Variation Example 5

[0135] The clutch pawl 447 can also be configured as described below. In variation 5, such as... Figure 13 As shown, the clutch pawl 447 has a first clutch pawl 447a and a second clutch pawl 447b.

[0136] The first clutch pawl 447a is pivotally mounted to the mechanism mounting plate 37 of the winding reel body 3. The first clutch pawl 447a is subjected to force by a torsion spring 448a against the clutch cam 49. The first clutch pawl 447a includes a first push part 63a.

[0137] The second clutch pawl 447b is pivotally mounted on the mechanism mounting plate 37 of the winding reel body 3. The second clutch pawl 447b is subjected to force on the clutch cam 49 by a torsion spring 448b. The second clutch pawl 447b includes a second pressing part 63b. The second clutch pawl 447b is spaced apart from the first clutch pawl 447a in the second rotation direction R2.

[0138] In this structure, when the operating part 39 of the clutch operating member 9 moves from the first position to the second position, the first pushing part 63a of the first clutch pawl 447a pushes the first pushed part 69a of the clutch cam 49. As a result, the clutch cam 49 rotates in the first rotational direction R1.

[0139] When the operating part 39 of the clutch operating member 9 moves from the third position to the second position, the second pushing part 63b of the second clutch pawl 447b pushes the second pushed part 69b of the clutch cam 49. As a result, the clutch cam 49 rotates in the first rotation direction R1. Even with this configuration, the clutch control mechanism 17 can be operated in the same way as in the aforementioned embodiment.
