2. Description of the Related Art Japanese Patent Application Laid-Open Nos. 48-90882 and 64-38964 discloses a fixed portion such as a reel housing and a handle rotatably supported by the reel housing. The inner and outer races of the one-way clutch are respectively attached to the rotating part which is drivingly connected to the motor, etc., and by the wedge action of the rolling member provided in the guide groove between the inner and outer races,
A reverse rotation prevention device for a fishing reel that regulates rotation in one direction and permits rotation in another direction to restrict rotation in one direction is described.

Japanese Patent Application Laid-Open No. 54-141285 discloses that a roller member is rotatably supported by a reel housing and a front portion of the reel housing is provided with a wedge effect of a rolling member in only one direction. And a locking piece of a regulating plate rotatably provided at the front of the bearing is projected into the guide groove of the rolling member, and the regulating plate is rotated by an operating rod supported by the housing. By doing so, there is described a fishing reel reversing prevention device in which a rolling member is switched to a non-wedge action position and can be rotated in another direction.

Japanese Unexamined Patent Publication No. 6-58348 discloses an annular holding member for regulating the forward and backward movement of the rolling member disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 54-141285, and the outer moving of the rolling member outside the annular holding member. Outer frame (outer ring)
A technology is described in which a non-rotational fitting is performed to unitize the reverse rotation prevention device.

[0005] Japanese Patent Application Laid-Open No. 6-225573 discloses an outer frame (outer ring) for restricting outward movement of a rolling member outside the annular holding member in the above-mentioned Japanese Patent Application Laid-Open No. 6-58348.
A technology for unitizing the anti-reverse device by switching the rolling member to the non-wedge action position by rotatably fitting the rolling member and rotating the annular holding member by the operating rod supported by the housing. Is described.

In the full specification of Japanese Utility Model Application Laid-Open No. 4-77774, a bearing that rotates in only one direction by the wedge action of a rolling member is provided on the inner peripheral surface of the recessed portion of the rotor. Techniques for improvement are described. The reverse rotation prevention device described in this publication disengages a claw actuated by an operation rod supported by a housing with a concave portion engraved on the inner periphery of an inner frame (inner ring) to disengage in a different direction. An outer frame (outer ring) that is rotatable and restricts outward movement of the rolling member is provided on the inner peripheral surface of the rotor recess.

[0007]

However, the above-mentioned JP-A-48-90882, JP-A-64-38964, and JP-A-54-141285, JP-A-54-141285, and JP-A-6-141285 have already been described.
In the reverse rotation prevention devices described in JP-A-58348 and JP-A-6-225573, the inward movement of the rolling member is restricted while the outward movement of the rolling member is regulated by an outer frame (outer ring). Therefore, since the rotation of the rotating part such as the rotor shaft barrel is restricted, the rotation is restricted at a position as close as possible to the rotation axis of the rotating part. In addition to this, when a large rotational force is applied, there is a problem that the guide slot expands and the outer frame (outer ring body) is deformed or damaged.

The bearing described in the full specification of Japanese Utility Model Application Laid-Open No. 4-77774 also regulates the outward movement of the rolling member by the outer frame (outer ring), and moves the inner member by the inner movement of the rolling member. Since the rotation is restricted, the same problem as described above is encountered.

Further, in the reverse rotation prevention device described in Japanese Utility Model Laid-Open Publication No. 4-77774, the pawl is engaged with and disengaged from the recess formed in the inner periphery of the inner frame, so that the rolling member is moved to the non-wedge action position. As a result, there is a problem that the operation speed is inferior to that in which rotation in another direction is possible. In addition, since an outer frame (outer ring) for restricting the outward movement of the rolling member is provided on the inner peripheral surface of the rotor concave portion, when the rotor is rotated at a high speed, the centrifugal force causes the rolling member to move inward. When it is separated from the frame (inner ring), it cannot be stopped quickly and reliably. To prevent this, if the elastic force of the elastic means that urges the elastic member to the rolling member in the inward direction (wedge action direction) is increased, the normal rotation will occur. There was also the problem of becoming heavy.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fishing reel reversing prevention device which is excellent in rotation regulating force and durability and excellent in operation speed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A fishing reel reverse rotation preventing device according to a first embodiment of the present invention will be described with reference to FIGS. In the first embodiment, the reverse rotation prevention device is applied to a dual-bearing type reel.

The dual-bearing type reel 1 includes a reel housing 2, a side plate 3 fixed to the reel housing 2, a spool 4 rotatably supported by the reel housing 2 and serving as a thread winding rotating body.
It has a handle 5 for rotating the spool 4. A handle shaft 6 serving as a rotating part is connected to the handle 5, and the handle shaft 6 is rotatably supported between the reel housing 2 and the side plate 3 via a bearing 7. Further, a master gear 8 is provided between the reel housing 2 and the side plate 3. The master gear 8 is connected to the handle shaft 6 via a well-known drag mechanism.
, And provided so as to be able to rotate integrally with the handle shaft 6 or to be relatively rotatable.

On the other hand, a spool shaft 9 rotatably supported by the reel housing 2 and the side plate 3 extends from the spool 4, and a binion gear 10 is detachably provided on the spool shaft 9 by a known clutch mechanism. ing. The pinion gear 10 meshes with the master gear 8. Therefore, the rotation of the handle 5 fixed to the handle shaft 6 is transmitted to the spool 4 via the master gear 8 and the pinion gear 10, and the spool 4 rotates in the fishing line winding direction or the feeding direction.

Next, the one-way clutch according to the first embodiment will be described. One-way clutch is mainly outer ring 1
1, an inner ring 12, a roller 13 as a rolling member (a roller, but a ball-shaped roller can be used), and a switching member 14. The handle shaft 6, which is a rotating portion, has a flange 15 fixed concentrically. The outer edge of the flange 15 has a cylindrical body 15A coaxial with the handle shaft 6, and the cylindrical body 15A
Is fixed to the inner peripheral surface of the annular outer ring body 11 whose inner peripheral surface is a perfect circle. On the other hand, a projecting tubular portion 16 is provided coaxially with the handle shaft 6 on the reel housing 2 serving as a fixed portion.
An inner race 12 is supported on an outer peripheral surface of the inner race 6 so as to face the outer race 11.

The inner peripheral surface of the inner ring body 12 is circular, while the outer peripheral surface is formed in a regular square shape, a substantially square shape, or a substantially square shape including a circular arc. Therefore, a substantially annular guide slot S is provided between the inner race 12 and the outer race 11, but the width of the guide slot S in the radial direction of the handle shaft is not constant.
As shown in FIG. 3A, the width of the guide slot S is the largest at the portion where the center of the outer peripheral side of the inner race 12 and the inner peripheral surface of the outer race 11 face each other, and Larger than diameter. In the portion where the corner of the inner race 12 and the outer race 11 face each other, the width of the guide slot S is the smallest and is smaller than the diameter of the roller 13.

A plurality of locking protrusions 16A projecting outward in the radial direction and extending in the axial direction are protruded from the outer periphery of the protruding cylindrical portion 16, while the locking protrusions 16A are formed on the inner peripheral surface of the inner ring body 12. A plurality of locking grooves 12a having a cross section slightly larger than the cross section contour are formed in the axial direction. The engagement between the locking ridge 16A and the locking groove 12a causes the inner race body 12 to project in the predetermined
6 is supported. As will be described later, the forward and reverse rotation of the spool 4 is allowed and the reverse rotation is prevented by the relationship between the groove width of the guide slot S and the roller 13, so that the inner race body 12 having a substantially quadrangular outer peripheral surface is mounted on the reel housing. The posture when attached to the body 2 is important for the timing of preventing the reverse rotation, but the engagement between the locking ridges 16A and the locking grooves 12a allows the inner ring body 12 to rotate in the correct posture. It is supported by the housing 2.

A plurality of rollers (rollers 12) of the inner ring are provided in the guide slot S between the inner and outer rings 12, 11.
4), which is the same as the number of sides on the outer peripheral surface of the above). The rollers 13 are supported by the switching member 14 so as to be movable in the circumferential direction of the outer race 11. The switching member 14
A disk-shaped member rotatably supported on the outer peripheral surface of the inner race 12, the reel housing 2, the outer race 11 and the flange 15.
Is rotatably arranged at the end of the. On the outer peripheral surface of the switching member 14, an engaging portion 14A protrudes outward in the radial direction.
An operating member 17 rotatably supported by the side plate 3 is engaged with 4A. An operation knob 17A is fixed to the operating member 17, and when the user operates the operation knob 17A, the switching member 14 is connected to the inner race body 12 via the engaging portion 14A.
Can be pivoted on.

On the disc portion of the switching member 14, positioning projections 14B are provided so as to sandwich the respective rollers 13 from both sides of the outer ring body 11 in the circumferential direction. Therefore, as the switching member 14 rotates, the individual rollers 13 also move in the same rotation direction. A spring 18 as elastic means is stretched between the engaging portion 14A of the switching member 14 and the reel housing 2, and constantly urges the switching member 14 and the roller 13 as a rolling member in the wedge direction. Here, the wedge direction means that the switching member 14 rotates counterclockwise on the inner ring body 12, and FIG.
, The direction in which the roller 13 moves in a direction in which the gap between the outer race 11 and the inner race 12 decreases.
Since the switching member 14 is urged in the wedge direction by using the spring 18, the wedge action when the handle shaft 6 rotates in the reverse direction is reliably realized.

The operation knob 17A and the side plate 3 are connected by a torsion coil spring (not shown). When the torsion coil spring is deformed beyond the dead point by the rotation operation of the operation knob 17A, the operation knob 17A is moved to either position.
The rotation position of A is held. That is, the biasing force of the torsion coil spring is set stronger than that of the spring 18, and even when the operation knob 17A is rotated to move the switching member 14 in the non-wedge direction, the torsion coil spring overcomes the biasing force of the spring 18, The operation knob 17A is held at the position after the rotation operation.

In the above configuration, when the operating knob 17A of the operating member 17 is in the down position, the torsion coil spring (not shown) overcomes the urging force of the spring 18 and the switching member 14
The roller 13 is not biased in the wedge direction, and as a result, as shown in FIGS. 2 and 3A, the roller 13 is positioned near the center of the side of the inner ring body 12 by the positioning protrusion 14B. In this case, since the distance between the side of the inner race 12 and the inner peripheral surface of the outer race 11 is larger than the diameter of the roller 13,
The rotation of the roller 13 and the inner race 12 is possible.
No rotation of the outer race 11 is prevented. Therefore, the forward and reverse operations of the handle 5 can be performed. That is, in FIG. 2, the wedge action is also performed when the handle shaft 16 rotates in the fishing line winding direction (forward rotation) indicated by the arrow X and when the handle shaft 16 reversely rotates in the fishing line payout direction (counter arrow X direction). Instead, the handle shaft 16 can rotate forward or reverse, so that the rotating spool 4 can rotate in the fishing line winding direction and the fishing line payout direction.

When the operation knob 17A is rotated in the direction of arrow Y from this state, the switching member 14 is rotated in the direction opposite to the direction of the arrow X with respect to the roller 13 which is a partly moving member. Is done. At this time, the movement of the roller 13 inward in the radial direction of the outer race 11 is regulated by the inner race 12, and the roller 13 moves outward when viewed in the radial direction of the outer race 11, and It cuts between the surface and the outer peripheral surface of the inner race 12. That is, the roller 13 moves toward the corner of the inner race 12, and the roller 13 is moved to a position where it can be tightly clamped between the inner race 12 and the outer race 11. In this state, when the handle is operated in the fishing line winding direction, the outer race 11 can rotate in the X direction in FIG. That is, when the rotation direction of the outer race 11 is the X direction, the pinching force of the outer race 11 and the inner race 12 against the roller 13 is weakened.
The inner race 12 does not prevent the outer race 11 from rotating in the X direction. That is, rotation in the fishing line winding direction becomes possible. In this case, since the switching member 14 is urged to rotate in the anti-X direction by the spring 18, the roller 13 does not move to the side between the corners of the inner race 12.

In this state, when the handle 5 is operated in the fishing line feeding direction, the outer race 11 tries to rotate in the anti-X direction, but the outer race 11 and the inner race 12
Roller 13 and the inner race 12 are connected to the outer race 11
Is prevented from rotating in the anti-X direction. That is, the rotation operation in the fishing line payout direction is prevented.

As described above, in the first embodiment, the inward movement of the roller 13 as a rolling member is
2 and the rotation of the handle shaft 6, which is a rotating part, is restricted by the outward movement of the roller 13.
Since rotation is regulated at a position as far as possible from the rotation axis of the handle shaft 6, a large rotation regulating force can be obtained. In addition, since the regulating surface that regulates the rotation of the handle shaft 6 serving as the rotating portion, that is, the inner peripheral surface of the outer ring body 11 has a large diameter,
The length of the regulation circumferential surface is increased as much as possible, and quick rotation regulation is possible. Further, since the rotation of the handle shaft 6 is restricted at a position as far as possible from the rotation axis of the handle shaft 6, even if a large rotation force is applied, the deformation and damage of the inner and outer races are hardly caused. The durability of the device can be improved.

Further, since the inner race 12 for restricting the inward movement of the roller 13 is provided on the reel housing 2 as a fixed portion, the restricting force and the restricting position at the time of the wedge action can be secured accurately. An inner race 12 for regulating the inward movement of the roller 13 is provided inside the roller 13.
, The reverse rotation of the handle shaft 6 is prevented by the outward movement of the roller 13, the separation of the roller 13 due to the centrifugal force due to the high-speed rotation of the handle shaft 6 can be prevented, and the quick and reliable reverse rotation can be stopped. .

Further, in the first embodiment, the engagement formed on the inner peripheral surface of the inner race body 12 is smaller than the sectional contour of the plurality of locking projections 16A projecting from the outer periphery of the protruding cylindrical portion 16. Since the cross-sectional profile of the stop rib 16A is slightly larger, the inner race 12 is slightly movable in the radial direction from the rotation axis. If the inner race 12 is tightly fitted to the protruding cylindrical portion 16, the inner race 12 and the handle shaft 6, which is a rotating part, are assembled during assembly.
It is necessary to make the concentricity of the outer race body 11 with the rotation shaft center strict, and precise formability is required. However, by supporting the inner race body 12 so as to be able to move slightly in the radial direction, strictness is required. No concentricity is required, and concentricity with the outer race 11 can be easily obtained by moving the inner race 12 in the radial direction. That is, the molding accuracy between the rotation axis of the rotating part and the rotating part or the fixed part can be roughened, and the productivity can be improved.

Further, since the switching member 14 is provided with the elastic means 18 for urging the roller 13 as a rolling member in the wedge action direction, it is possible to apply an elastic force in the wedge action direction without providing each roller with an elastic means. Therefore, the switching of the respective rollers 13 to the wedge action position or the non-wedge action position can be reliably performed in synchronization with each other, and simplification of these assembling operations and prevention of assembly errors can be achieved.

When the user operates the operation knob 37A, the operating member 37 rotates around the axis, and the disc portion 37B rotates eccentrically, so that the urging force of the spring 38 on the projecting portion 34A changes. Here, the spring 38 switches the switching member 3 so that the roller 33 as a rolling member moves in the non-wedge direction.
4 are energized. In FIG. 5, the spring 38 urges the protrusion 34A in a direction in which the protrusion 34A rotates clockwise. In order to define the rotation range of the switching member 34, a pair of stopper members 40 </ b> A, 40 </ b> A protrude from the front surface of the reel housing 22 so as to be able to come into contact with the protrusion 34 </ b> A of the switching member 34.

An unillustrated torsion spring is interposed between the inner race 32 and the annular holder 39. The torsion spring urges the annular holder 39 and the roller 33 serving as a rolling member in the wedge direction, but is set smaller than the urging force of the spring 38.

In the above configuration, when the operation knob 37A of the operating member 37 is rotated in one direction, the operating member 3
7, the disk portion 37 of the operating member 37 centered on the rotation axis 37D.
5B rotates counterclockwise in FIG. 5 and urges the protrusion 34A of the switching member 34 clockwise via the spring 38, and the protrusion 34A comes into contact with the stopper member 40A on the right side in FIG. In this state, the projecting portion 34A is moved by the spring 38 in FIG.
Of the roller 33 is
Is located near the center of the side of the inner race 32 by the metal reinforcing member 39A of the annular holder 39. At this time, since the distance between the side of the inner race 32 and the inner peripheral surface of the outer race 31 is larger than the diameter of the roller 33, the roller 33 itself can rotate. , Outer ring 1
No rotation of 1 is prevented. Therefore, the forward and reverse operations of the handle 25 can be performed, and the rotor 23 serving as the line winding rotating body can rotate in the fishing line winding direction and the fishing line payout direction.

When the operating knob 37A is rotated in the opposite direction from this state, the operating member 37 rotates clockwise in FIG. 5 around the axis 37D, and the disk portion 37B at the tip rotates eccentrically, and 38 is separated from the protrusion 34A. But,
The annular holding body 39 is urged to rotate in the wedge action direction by a torsion spring (not shown), so that the switching member 34 also rotates in the same direction. At this time, the pin 3 is inserted into the arc-shaped slot 34a.
6 comes into sliding contact with the protrusion 34A on the left stopper member 4
Contact with 0A. Therefore, the roller 33 held by the annular holder 39 also moves in the wedge direction (counterclockwise). That is, the roller 33 moves toward the corner of the inner race 32, and the roller 33 moves in a direction in which the roller 33 is tightly held between the inner race 32 and the outer race 31. In this state, when the handle 25 is operated in the fishing line winding direction, the rotation direction of the outer race 31 is a direction in which the pinching force of the outer race 31 and the inner race 32 on the roller 33 is weakened. The inner race 32 does not prevent the rotation of the outer race 31 and the fishing line can be rotated in the fishing line winding direction.

In this state, when the handle is operated in the fishing line dispensing direction, the outer ring 31 also tries to rotate, but the rotating direction of the outer ring 31 increases the pinching force of the outer ring 31 and the inner ring 32 against the roller. Since the direction is the direction (the direction in which the wedge action is strengthened), the roller 33 and the inner race 32 prevent the outer race 31 from rotating. That is, the rotation operation in the fishing line payout direction is prevented.

When the roller 33 is at the wedge action position, even if the operation lever 37A is operated to rotate the switching member 34 in the non-wedge direction, the roller 33 is moved to the outer ring body 31 and the inner ring body 32.
The switching member 34 cannot rotate in the non-wedge direction because it cuts into the gap. If the operating member 37 is directly connected to the protruding portion 34A of the switching member 34, when the operating lever 37A is forcibly operated to rotate the switching member 34, the switching member 34, the roller 33, Inner ring 32, outer ring 3
There is a possibility that the operation transmission system constituted by 1 may be deformed or damaged. In this embodiment, the spring 38 is
And the switching member 34, in a state where the roller 33 bites between the outer race 31 and the inner race 32,
Even if the operation lever 37A is operated, only the spring 38 is deformed, and deformation and breakage of these operation transmission systems can be prevented.
The switching member 34 can rotate in the non-wedge direction when the biting state of the roller 33 is eliminated.

As described above, in the second embodiment, similarly to the first embodiment, the inward movement of the roller 33 serving as a rolling member is restricted by the inner ring body 32 and the outer side of the roller 33 is controlled. Since the movement restricts the rotation of the rotor 23, the rotation of the rotor is restricted at a position as far as possible from the rotation axis of the rotor 23, so that a large rotation restricting force can be obtained. Since the inner peripheral surface of the outer race body 31, which is the restricting surface for restricting the rotation of the rotor 23, has a large diameter, the length of the restricting circumferential surface is made as long as possible, and rapid rotation can be restricted. Since the rotation of the rotor 23 is regulated at a position as far as possible from the axis of rotation of the rotor 23, even if a large rotational force is applied, deformation and damage of the inner and outer races are unlikely to occur, and the durability of the device is improved. Performance can be improved. Further, similarly to the first embodiment, the inner ring body 32 that regulates the inward movement of the roller 33 is provided on the reel housing 22 as a fixed portion, so that the regulating force and the regulating position at the time of wedge action are accurately secured. can do. An inner ring 32 is provided inside the roller 33 for restricting the inward movement of the roller 33. The inner ring 32 prevents the reverse rotation of the rotor 23 by the outward movement of the roller 33. As a result, separation of the roller 33 can be prevented, and quick and reliable reverse rotation can be stopped.

In the second embodiment, the metal annular body 35 for fixing the outer race 31 is formed separately from the rotor 23 as a rotating body.
Compared with the case where the metal ring is provided, there is no need to consider the exact concentricity between the rotation axis of the rotor 23 and the axis of the outer race at the time of molding, and the mounting position of the metal annular body 35 to the rotor 23 is adjusted. By doing so, concentricity can be obtained. In addition, since the rotor is formed separately, the rotor can be made of a lightweight material such as a resin, so that the weight of the entire fishing tackle and the centrifugal force can be reduced. Therefore, there is an advantage that the rotation of the rotor can be easily balanced.

Further, since the metal annular body 35 for fixing the outer ring body 31 is supported so as to be movable in the radial direction with respect to the rotor 23 which is a rotating body, the metal annular body 35 in the radial direction of the rotor 23 of the metal annular body 35 is , The concentricity between the rotor 23 and the outer race body 31 can be more easily realized.

Further, since the inner race 32 is substantially regular octagon,
The length of the side can be formed shorter than the length of the side of the square inner race body 12 of the first embodiment, and the reverse rotation preventing operation can be performed more quickly.

Further, since the roller 33 as a rolling member is restricted from moving back and forth (moving in the axial direction) in the holding hole of the annular holding member 39 rotatably fitted to the outer periphery of the inner race 32, the fixing member is fixed. Inner ring 3 provided on a reel housing 22
The operation of the roller can be performed together with the ring-shaped holding member between the outer ring body 31 supported by the rotor, which is the rotating part, and the operation of the roller can be stabilized, and the accurate wedge action can be performed. Further, since the roller 33 is held by the annular holding member 39 rotatably fitted to the outer periphery of the inner ring body 32, these components can be unitized, the assembling work can be simplified, and assembly errors can be prevented. I can do it.

A switching member 34 is attached to an annular holder 39 rotatably fitted to the inner race 32, and the switching member 34 is attached to an operating member 37 supported by the reel housing 22 as a fixed portion.
By rotating the roller 33 together with the annular holding body 39 by the switching member 34 to the non-wedge action position, the rotation restriction can be released. Therefore, by operating the operation knob 37A, the rotation together with the annular holding body 39 is performed. By switching the roller 33 to the wedge action position or the non-wedge action position, the rotation of the one-way clutch in one direction can be restricted and released. Accordingly, the reverse rotation and the reverse rotation in the exchange with the fish when catching the fish can be quickly and reliably switched, and troubles such as thread breakage due to this switching mistake can be prevented.

A reverse prevention device for a fishing reel according to a third embodiment of the present invention will be described with reference to FIGS. In the third embodiment, a reverse rotation prevention device is applied to a spinning reel as in the second embodiment. However, the spinning reel has a reel housing (fixed portion) and a rear portion of a rotor (rotating portion). The second embodiment is different from the second embodiment in that a rolling type one-way rotating clutch is provided between the inner surface of the recess formed. 6, the same reference numerals as those in FIGS. 4 and 5 indicate the same members.

In the third embodiment, a disk-shaped outer race 131 is fixed to the inner peripheral surface of the concave portion of the rotor 123 as a rotating portion. The distal end of the reel housing 122, which is a fixing portion, is located in the recessed portion, and holds the bearing 128 to rotatably support the shaft cylinder 127. The inner race 132 is fixed to the front end surface of the reel housing 122. The inner peripheral surface of the inner race 132 is circular, and is disposed concentrically with the shaft cylinder 127. On the other hand, the outer peripheral surface of the inner race 132 is a substantially regular octagon as in the second embodiment.

The annular holder 15 is provided on the distal end surface of the inner race 132.
0 is fixed by a pin 152. Inner ring 1
32, a flange 151 is integrally provided on the rear end surface side, and the flange 151 is fixed to the front end surface of the reel housing 122 by screwing or the like. A roller 133 serving as a rolling member is disposed in an annular guide groove between the inner and outer races 132 and 131, and movement of the roller 133 in the front-rear direction (axial direction) is prevented by the annular holder 150.

Eight holding holes extending in the circumferential direction of the outer ring body 131 are formed in the annular holding body 150 at equal intervals at the same radius. In each of the holding holes, a roller 133 and a roller 123 are wedge-shaped. A spring (not shown) for urging in the direction is disposed, and an operating rod 134B of a switching member 134 described later is provided so as to be able to enter and retract.

That is, when the switching member 134 moves forward to the non-wedge position in the holding hole (not shown), the spring, the roller 133, and the operating rod 134B are arranged in this order when viewed in the circumferential direction of the outer race 131.

In the above configuration, when the operating knob 137A is rotated clockwise, the switching member 134 is retracted via the operating member 137, and therefore the distal end of the operating rod 134B is retracted from the holding hole of the annular holder 150. Then, the roller 133 is urged in the holding hole in the wedge direction by a spring (not shown). That is, the roller 133 is urged in the corner direction of the inner race 132, and the rotor 123 is in a state in which the rotor 123 can rotate forward and cannot rotate reversely by the same wedge effect as in the above-described embodiment.

When the operation knob 137A is rotated counterclockwise, the switching member 134 moves forward through the operating member 137, and thus the operating rod 134 is inserted into the holding hole of the annular holding body 150.
The tip of B enters. Therefore, the roller 1 moves on the inclined surface 134C of the operating rod 134B against the urging force of a spring (not shown).
The roller 33 rides up and the roller 13 is urged in the non-wedge direction. That is, the roller 133 is located in the center direction of the side of the inner race 132, and the rotor 123 can rotate forward and reverse as in the above-described embodiment.
