  By the way, during the winding operation at the time of actual fishing, the rotating operation is usually performed while applying irregular force continuously and discontinuously while gripping and holding the handle knob and applying force to the front, rear, left and right. For this reason, in the screwing configuration of the operating cylinder in the folding device disclosed in Patent Document 1 described above, the operating cylinder that holds the handle arm upright may rotate loosely during the winding operation of the handle, As a result, there is a problem that the handle becomes loose and a smooth winding operation cannot be performed.

  According to the folding device disclosed in Patent Document 2 described above, the operating cylinder is configured to generate a frictional resistance in the rotational direction by the spring and the ball, but the operating cylinder rotates with a predetermined rotational force. In fact, there is no certainty under severe practical conditions in which irregular force acts during the winding operation. In addition, there is a problem that the ball does not engage with the concave portion of the concavo-convex portion, and a position where no frictional resistance force is generated in the rotational direction is generated.

  The present invention has been made on the basis of the above-described problem, and in a fishing reel provided with a handle folding device capable of switching the handle to both the upright holding state and the folded state, a reliable operation cylinder is provided. An object of the present invention is to provide a fishing reel provided with a handle folding device that has a relaxation preventing function and does not rattle the handle during actual fishing.

  In order to achieve the above-described object, a fishing reel according to the present invention is provided on the outer periphery of the drive shaft with respect to a base end surface of a handle that is foldably supported at an end of the drive shaft of the reel body. In the configuration including a handle folding device that allows the handle to be switched between a folded state and an upright state with respect to the drive shaft by rotating the operation cylinder in the axial direction, the handle folding device includes: A one-way clutch interposed between the operation cylinder, allowing rotation of the operation cylinder in a direction to hold the handle upright with respect to the drive shaft, and preventing rotation of the handle in a folding direction; and And switching means for canceling the rotation blocking state.

  According to the above configuration, the operation cylinder cannot be rotated in the direction in which the handle is folded by the one-way clutch interposed between the drive shaft of the handle and the operation cylinder. For this reason, even if the handle is rotated in various modes during actual fishing, the operation cylinder does not relax, and the handle arm does not rattle. Further, when the handle is folded, by operating the switching means to cancel the rotation-prevented state of the one-way clutch, the operation cylinder can be rotated in the loosening direction, and thereby the handle can be folded.

  According to the present invention, when the handle is rotated while the handle is held upright, the operation cylinder for switching the handle between the stand-up holding state and the folded state is maintained in an anti-relaxation state, so that the handle becomes loose during actual fishing. Thus, a fishing reel that can be smoothly rotated is obtained.

  1 to 6 are diagrams showing an embodiment of the present invention. FIG. 1 is a diagram showing a configuration example of a fishing reel (spinning reel) equipped with a handle according to the present invention. FIG. 1 is a cross-sectional view taken along the line AA in FIG. 1. FIG. 3 is an enlarged view showing a support portion of the handle in FIG. 2. FIG. 4 is a view showing a folded state of the handle. FIG. 6 is a cross-sectional view taken along the line BB in FIG. 3 and FIG. 6 is a cross-sectional view taken along the line CC in FIG.

  The reel body 2 of the spinning reel 1 is integrally formed with a reel leg 2a to be attached to a fishing rod. A rotor 3 that is rotatably supported in front of the reel leg 2 is synchronized with the rotational movement of the rotor 3. A spool 5 that is movably supported is disposed. Further, a drive shaft (handle shaft) 6 is rotatably supported on the reel body 2 via a bearing 6a, and a handle 7 is attached to the protruding end. Further, a known take-up drive mechanism 9 connected to a face gear 8 attached to the handle shaft 6 is disposed in the reel body 2. By rotating the handle 7, the face gear is rotated. The rotor 3 is rotationally driven and the spool 5 is reciprocated via the winding drive mechanism 9 and the winding drive mechanism 9.

  The handle 7 includes a handle knob 7a that can be picked by a finger of a hand and a handle arm 7b that rotatably supports the handle knob 7a, and is formed so as to protrude in an axial direction at an end of the handle shaft 6. The stand 6b is supported so as to be rotatable. Specifically, the handle arm 7b has a base 7c that can be rotated between a standing position (see FIG. 3) and a folded position (see FIG. 4) by a handle stop pin 6c attached to the stand 6b. It is supported and is configured to be switched between the folded state and the standing state with respect to the drive shaft 6 by the handle folding device 10.

  The handle folding device 10 in this embodiment includes a nut 12 that is screwed into a male screw portion 6d formed at an end of the drive shaft 6, and an operation cylinder 13 that can rotate integrally with the nut so as to rotate the nut 12. And a support member 15 that is attached to the drive shaft 6 so as to be integrally rotatable and supports the operation tube 13 from the inner peripheral side, and between the nut 12 (the operation tube 13 that rotates together with the nut 12) and the drive shaft 6. A one-way clutch 20 interposed therebetween.

  The reel body side of the nut 12 is fixed to the inner peripheral surface of the operation cylinder 13, and the nut 12 is screwed / retracted along the axial direction by rotating the operation cylinder 13. Yes. In this case, the front end surface 12a of the nut 12 abuts against the engagement surface (base end surface) 7d of the base portion 7c of the handle arm 7b, and the nut 12 is screwed forward to the front end side. The front end surface 12a of the nut 12 is brought into contact with the engagement surface 7d to hold the handle 7 in an upright state (see FIG. 3), and the nut 12 is screwed back to the reel body side. The handle arm 7b can be turned around the handle stop pin 6c apart from 7d, and the handle 7 can be folded (see FIG. 4).

  In addition, on the outer periphery of the operation cylinder 13, a friction region, for example, a groove 13a formed so as to extend in the axial direction at a predetermined interval so that the operation cylinder 13 (nut 12) can be easily rotated. Is formed.

  As shown in FIG. 6, the one-way clutch 20 is prevented from rotating by the nut 12, and an outer ring 23 in which a wedge region 21 and a free region 22 are continuously formed in the circumferential direction at a predetermined interval, and the wedge region 21 and a plurality of rollers 25 located in the free region 22, a holder 26 that holds each roller 25, and a biasing spring 27 that is provided in the holder 26 and biases each roller 25 toward the wedge region 21. It has. In this case, as shown in FIG. 6, the direction of the one-way clutch 20 is rotated by moving each roller 25 to the free region 22 when the nut 12 is rotated to the direction D1 (direction in which the handle stands upright) D1. Is set so that each roller 25 moves to the wedge region 21 and is prevented from rotating when the nut 12 is rotated in the direction D2 (the direction in which the handle is folded) D2.

  That is, the one-way clutch 20 as described above is interposed between the drive shaft 6 and the nut 12 so that the nut 12 can rotate only in the tightening direction D1 and is prevented from rotating in the loosening direction D2. become. Therefore, during actual fishing, even if the handle 7 is wound in various ways (the drive shaft 6 is driven to rotate in the direction D1 in FIG. 6), the nut 12 is not loosened. The handle 7 is reliably prevented from rattling and a smooth winding operation is always possible.

  Further, the handle folding device 10 includes a switching unit 30 so as to release the rotation prevention state of the one-way clutch 20 described above. The switching means 30 is provided so as to engage with the one-way clutch 20, and the state of the one-way clutch 20 can be changed so that the operation cylinder 13 can be rotated in the direction D2 in which the operation cylinder 13 is loosened when the handle 7 is folded. The operation cylinder is configured to switch from the rotation blocking state to the rotatable state.

  Specifically, the switching means 30 of the present embodiment is configured to include a substantially disc-shaped operation plate 31 that can rotate integrally with the cage at the end of the cage 26. In this case, the operation plate 31 can be integrally rotated together with the retainer by engaging with the retainer 26 at the central portion thereof (see FIG. 5), and is fitted to the outer peripheral surface of the operation tube 13. The movement in the axial direction is restricted by the retaining ring 13b. The operation plate 31 has an operation piece 32 formed in the radial direction. The operation piece 32 is formed in an arcuate opening 13c cut out at a predetermined angle on the outer peripheral surface of the operation tube 13. Further, they are arranged so that they can be operated with a finger.

  According to the configuration of the switching means 30 as described above, the cage 26 is rotated counterclockwise in FIG. 6 by rotating the operation piece 32 of the operation plate 31 counterclockwise with a finger in FIG. The rollers 25 are rotated in the turning direction, and each roller 25 moves to the free region 22. As a result, the operation cylinder 13 can freely rotate in the direction of the arrow D2, which is the direction in which the nut 12 is loosened. Finally, as shown in FIG. 4, the distal end surface 12a of the nut 12 is separated from the engagement surface 7d. Thus, the handle 7 can be folded.

  Note that the switching means 30 described above may be configured so that it can be rotated in the direction of loosening the operation cylinder 13 by releasing the rotation blocking state of the one-way clutch 20, and other than the above-described embodiment. For example, it can be configured as shown in FIGS.

  In this configuration example, a ratchet 35 is fixed to the outer ring 23 of the one-way clutch 20 so as to be non-rotatable (may be formed integrally with the outer ring), and supported on the nut 12 via a support pin 36 so as to be swingable. The stopper 37 is engaged. The stopper 37 is pressed and urged at one end side 37 a by a leaf spring 38 interposed between the stopper 12 and the pawl 37 b on the other end side is always engaged with the ratchet 35. Yes. The nut 12 and the operation cylinder 13 are formed with a split groove 40 along the drive shaft direction so that the stopper 37 can swing and the one end side 37a can be pressed.

  According to such a configuration, when the operation cylinder 13 is rotated in the tightening direction D1, the stopper 37 is not locked with respect to the ratchet 35, and the outer ring 23 moves to a position where each roller 25 can freely rotate. The rotation in the tightening direction is possible, and the rotation in the loosening direction D2 is performed by rotating the outer ring 23 integrally with the ratchet 35 and the stopper 37 in a locked state. Since it shifts, it is in a blocked state.

  When the handle is folded, the stopper 37 is separated from the ratchet 35 by pressing the one end side 37a of the stopper 37 against the urging force of the leaf spring 38, so that the engagement between the outer ring 23 and the operation cylinder 13 is increased. Cancel the joint relationship. Thus, the operation cylinder 13 is disengaged from the one-way clutch 20 and can be rotated in the loosening direction D2. That is, the handle can be folded by rotating the operation cylinder 13 while pressing the one end side 37a.

  Even in such a configuration, the same effects as those of the above-described embodiment can be obtained.

  Although the embodiment of the present invention has been described above, the present invention is directed to the one-way clutch so that the operation cylinder 13 (nut 12) that is rotated when folding the handle cannot be rotated in the loosening direction during actual fishing. The configuration of each component, for example, the handle 7, the operation cylinder 13, and the nut 12, and the mounting method are not limited to the above-described embodiment, and various modifications are possible. Is possible. For example, the nut 12 and the operation cylinder 13 described above may be integrally formed with each other, instead of fixing separate members. The switching means 30 only needs to be capable of switching so that the one-way clutch 20 acting as described above can be rotated so that the operation cylinder can be rotated in a loosening direction. The position and the like can be appropriately changed.
