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 frame plate 2 forming a reel housing, a side plate 3 fixed to the frame plate 2, a spool 4 rotatably supported by the frame plate 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 on the side plate 3 via a bearing 7. Here, a shaft portion 2 </ b> A extending in the axial direction of the handle shaft 6 extends integrally with the frame plate 2.
Has a sleeve shape, the shaft portion 2A is inserted concentrically, and is supported by the shaft portion 2A so as to be rotatable with respect to the shaft portion 2A and not slidable in the axial direction.

A master gear (not shown) is provided on the handle shaft 6 between the frame plate 2 and the side plate 3. The master gear is connected to the handle shaft 6 via a well-known drag mechanism (not shown), and is provided so as to be integrally rotatable with the handle shaft 6 or relatively rotatable. On the other hand, spool 4
A spool shaft 9 rotatably supported by the frame plate 2 and the side plate 3 extends, and a binion gear 10 is detachably provided on the spool shaft 9 by a known clutch mechanism (not shown). The pinion gear 10 meshes with a master gear (not shown). Therefore, the rotation of the handle 5 fixed to the handle shaft 6 is transmitted to the spool 4 via the master gear 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 race 12, a roller 13 as a rolling member, and an annular holder 14 as a holder. The outer race 11 has a bottom surface and a cylindrical portion having a bottomed cylindrical shape, and the bottom surface is fixed to the handle shaft 6. The cylindrical portion is provided concentrically with the axis of the handle shaft 6, and its inner peripheral surface forms a regular octagon serving as a cam surface. Therefore, the rotation of the handle shaft 6 causes the outer race 11
Rotates integrally with the handle shaft 6.

The inner race 12 has a cylindrical portion and a flange portion,
The inner peripheral surface of the cylindrical portion is rotatably supported by the handle shaft 6,
The outer peripheral surface is a perfect circular cylindrical shape. The flange portion has a protrusion 12A protruding forward. Here, a long hole 2 a extending in the radial direction with respect to the rotation axis of the handle shaft 6 is formed in the frame plate 2 serving as a fixed portion. Then, the projection 12A of the inner race 12 is engaged with the elongated hole 2a, so that the inner race 12 is supported by the frame plate 2 and the mounting position of the inner race 12 with respect to the frame plate 2 in the radial direction is adjustable. . With this configuration,
There is no need to consider the exact concentricity between the rotation axis of the handle shaft 6 and the inner race 12 at the molding stage, so that the molding accuracy can be made rough and the productivity can be improved.

The outer peripheral surface of the inner race 12 faces the inner peripheral surface of the outer race 11. 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 from the axis of the handle shaft 6 is not constant, and FIG. In the portion where the outer peripheral surface of the inner race body 12 and the center of the side of the regular octagon of the inner peripheral surface of the outer race body 11 face each other, the width of the guide slot S is the smallest and the roller 13 Smaller than the diameter of. On the other hand, in a portion where the outer peripheral surface of the inner race 12 and the regular octagonal corner of the inner periphery of the outer race 11 face each other, the width of the guide slot S is the largest and is larger than the diameter of the roller 13.

In the guide slot S between the inner race 12 and the outer race 11, an annular holding member 14 formed integrally with the outer race 11 is provided.
Is arranged. That is, the inner peripheral surface of the annular holder 14 is circular, and is rotatably supported on the outer peripheral surface of the inner ring body 12. The outer peripheral surface of the annular holder 14 is a regular octagon, and It matches the peripheral shape. Ring holder 14
Are formed with holding holes 14a at equal intervals in the circumferential direction. The holding holes 14a are formed so as to penetrate in the radial direction of the annular holding body 14, and the rollers 13 as rolling members are arranged in the respective holding holes 14a.

Here, the roller 13 is movable in the holding hole 14a in the circumferential direction and the radial direction of the annular holding member 14, but is movable in the front-rear direction (axial center) by a wall portion 14A defining the holding hole 14a. Direction). Therefore, the roller 13 is provided so as to rotate together with the outer race 11 in the guide slot S between the inner and outer races 12, 11.
Since the roller 13 is restricted from moving back and forth (moving in the axial direction) by the walls 14A and 14A of the annular holding member 14, a wedge action position of the roller 13 between the inner ring 12 and the outer ring 11, which will be described later. Alternatively, switching to the non-wedge action position can be stabilized, and accurate wedge action can be performed. Roller 13
Are held by the annular holder 14, so that these components can be unitized, the assembling work can be simplified, and assembling errors can be prevented.

Each of the holding holes 14a has a roller 1 therein.
A spring body 16 for providing an elastic force in the wedge direction is provided on 3. Here, the wedge direction refers to the outer race 11 and the annular holder 1.
4 means the direction in which the roller 13 moves toward the center of the side of the polygonal cam surface of the outer race 11 when the roller 13 rotates, and the direction in which the roller 13 cuts into the gap between the inner race 12 and the outer race 11. is there. The non-wedge direction refers to the direction in which the roller 13 moves in the direction of the corner of the polygonal cam surface of the outer race 11 when the outer race 11 and the annular holder 14 rotate in opposite directions.

When viewed in the circumferential direction of the annular holding member 14, one wall 14b of the holding hole 14a is located near the center of the side of the cam surface of the outer race body 11 and faces the roller 13; The spring body 16 is in contact with the other wall 14c. Accordingly, the annular holding member 14 is arranged in the guide groove S, and the roller 13 is arranged in the holding hole 14 a of the annular holding member 14 so as to be able to contact the inner race 12 and the outer race 11, and the roller 13 is annular. It is urged by the spring body 16 in the circumferential direction of the holding body 14 and in the direction toward the center of the side of the cam surface of the outer ring body 12 (wedge action direction).

A switching member 17 is provided concentrically with the handle shaft 6. The switching member 17 is rotatable with respect to the handle shaft 6 and slidably provided in the axial direction of the handle shaft 6. A projection 17A that projects forward from the switching member 17 is provided. The tip of the projection 17A forms an arc-shaped inclined surface 17B, and the forward movement of the switching member 17 causes the projection 17A to move between the roller 13 and the wall 14b facing the roller 13 of the holding hole 14a of the annular holding body 14. It is possible to enter between. When the projection 17A enters between the roller 13 and the wall 14b, it provides a non-wedge action position for the roller 13 so that the projection 17A
4b provides the wedge action position of the roller 13 when it exits from the position between the roller 4b and the roller 4b. When the switching member 17 slides forward, the projection 17A can enter the holding hole 14a.
When the roller 7 is retracted, it separates from the roller 13 but the holding hole 1
4a is set to a length that still engages with the wall.
Therefore, the relative positions of the outer race 11, the annular holder 14, and the switching member 17 in the rotational direction are always constant by the projections 17A.

A switching mechanism 20 (details shown in FIGS. 3 and 4) is provided for performing the forward and backward operations of the switching member 17. The switching mechanism 20 has an operation knob 21, an operating member 22, a clutch cam 23 and a clutch lever 24. The operation knob 21 is rotatably supported outside the side plate 3, and the operating member 22 is inside the side plate 2 and connected to the operation knob 21. Therefore, the operating member 22 can be rotated about its axis 22a by rotating the operation knob 21. On the other hand, a disk portion 22A is provided on the distal end side of the operating member 22, and a boss portion 22B is provided integrally with the disk portion 22A.
The boss portion 22B is provided at a position eccentric from the rotation axis 22a of the operating member 22, and a spring 22C as a biasing means is fixed thereto. The operation knob 21 has a dead point spring (not shown) interposed between the operation knob 21 and the side plate 3.
The rotation position after the operation of (1) can be held.

The clutch cam 23 is provided at a position immediately before the side plate 3 so as to be rotatable around the handle shaft 6. The clutch cam 23 has a pair of projections 23 projecting forward.
A is provided, and an arm 23B that can contact the spring 22C of the operating member 22 and a coil spring connection arm 23C are provided. Here, the spring 22C applies elastic force in the non-wedge direction to the roller 13 housed in the holding hole 14a. In order to make it easy for the clutch lever 24 to ride on the projection 23A by the rotation of the clutch cam 23, an inclined surface is formed on the projection 23A. A stopper member 3A protruding forward from the side plate 3 is located on the side of the arm 23B to restrict the counterclockwise rotation of the arm 23B in FIG. Further, a coil spring locking portion 3B extending from the side plate 3 extends to the side of the coil spring connecting portion 23C, and the coil spring 25 is locked between the coil spring locking portion 3B and the coil spring connecting arm 23C. It is urged to rotate counterclockwise.

The clutch lever 24 is located immediately in front of the clutch cam 23 and is coaxially connected to the switching member 17 so as not to be movable in the axial direction. It is provided movably in the axial direction. A pin 26 extends forward from the side plate 3, and the clutch lever 24 is in sliding contact with the pin 26, and the longitudinal movement of the clutch lever 24 is guided by the pin 26. A retaining member 26A is fixed to the tip of the pin 26, and a coil spring 27 is interposed between the retaining member 26A and the front end surface of the clutch lever 24 around the pin 26. Therefore, the clutch lever 24 is connected to the coil spring 2
7 is urged in the direction of the side plate 3 (rearward).

Next, the operation of the above-described apparatus for preventing reverse rotation of a fishing reel will be described. 2 and 4 show the state where the roller 13 is in the non-wedge action position. That is, when the operation knob 21 is rotated to rotate the disk portion 22A of the operation member 22 in the counterclockwise direction in FIG. 4, the spring 22C presses the arm portion 23B to attach the clutch cam 23 to the coil spring 25. Rotate clockwise in FIG. 4 against the force. By this rotation, the projection 23A of the clutch cam 23 is aligned with the clutch lever 24, and the clutch lever 24 rides on the projection 23A,
The clutch lever 24 moves forward against the urging force of the coil spring 27. Accordingly, the switching member 17 connected to the clutch lever 24 moves forward and the inclined surface 17 of the switching member 17
B enters the holding hole 14a, and the roller 13 and the wall 14b
It will be located in between. Accordingly, the roller 13 moves counterclockwise in FIG. 2 (downward in FIG. 3) to the non-wedge action position against the urging force of the spring 16, that is, toward the corner of the cam surface of the outer race 11. At the position after the movement of the roller 13, the distance between the circular outer peripheral surface of the inner race 12 and the inner peripheral surface of the outer race 11 is larger than the diameter of the roller 33.

In the non-wedge action position shown in FIG. 2, when the handle shaft 6 is rotated in the fishing line winding direction (forward rotation) indicated by the arrow X in FIG. 2, the cam surface on the inner periphery of the outer race 11 and the inner race are rotated. Body 1
Roller 13 in the direction in which the distance from the outer circumferential surface of
Is about to move, and the fishing line payout direction indicated by the arrow X (reverse rotation)
When the handle shaft 6 rotates, the roller 13 tends to move in a direction in which the distance between the inner peripheral cam surface of the outer race 11 and the outer peripheral surface of the inner race 12 is reduced. However, in this state,
Since the movement of the roller 13 in the counterclockwise direction (wedge position) in FIG. 2 is regulated by the projection 17A of the switching plate 17, the handle shaft 6 integrated with the outer race 11 is rotated in either the forward or reverse direction. However, the rotation is not restricted. That is, fishing line winding,
Feeding operation is possible.

Next, when the operation knob 21 is rotated in the opposite direction to rotate the disk portion 22A of the operating member 22 clockwise in FIG. 4, the spring 22C separates from the arm portion 23B, and the clutch cam Reference numeral 23 rotates counterclockwise in FIG. 4 by the urging force of the coil spring 25, and stops rotating by contacting the stopper member 3A. By this rotation, the projection 23A of the clutch cam 23 is disengaged from the clutch lever 24, and the clutch lever 24 moves rearward by the urging force of the coil spring 27. Therefore, the switching member 17 connected to the clutch lever 24 retreats, the inclined surface 17B of the switching member 17 retreats from the holding hole 14a, and separates from the roller 13. Accordingly, the roller 13 is moved counterclockwise in FIG. 2 (upward in FIG. 3) by the urging force of the spring 16 so that the roller 13 comes into contact with the wall portion 14b of the holding hole 14a (FIG. 3) and moves to the wedge action position. To reach. That is, it moves to the center of the side of the cam surface of the outer race 11.

At the position after the movement of the roller 13, the distance between the circular outer peripheral surface of the inner race 12 and the inner peripheral surface of the outer race 11 is
It is smaller than the diameter of the roller 33. In this state, when the handle shaft 6 is rotated in the fishing line winding direction (forward rotation) indicated by the arrow X by operating the handle 5, the distance between the cam surface on the inner periphery of the outer race 11 and the outer periphery of the inner race 12 is set. Since the roller 13 moves in the direction in which the roller 13 expands, the roller 13 can continuously rotate the handle shaft 6 that rotates integrally with the outer race body 11 without wedge action. However, when the handle 5 is rotated in the reverse direction to rotate the handle shaft 6 in the fishing line payout direction (reverse rotation) indicated by the arrow X, the distance between the cam surface on the inner periphery of the outer race 11 and the inner periphery of the inner race 12 is Since the roller 13 tends to move in the direction in which the diameter of the handle 13 is reduced, the handle shaft 6 integrated with the outer race body 11 cannot be rotated in the reverse direction by the wedge action of the roller 13, and the reverse rotation operation of the handle 5 becomes impossible.

When the roller 13 is at the wedge action position and the operation knob 21 is operated to move the switching member 17 forward, the roller 13 bites into the outer ring body 11 and the inner ring body 12 firmly. In this case, the protrusion 17A at the tip of the switching member 17 cannot enter between the roller 13 and the wall 14b. Therefore, even if the operation knob 21 is operated, the switching member 17
Cannot move forward. The arm 23 of the clutch cam 23
Assuming that B is directly connected to the operating member 22, when the operating knob 21 is forcibly operated to rotate the clutch cam 23, the outer peripheral surface of the inner race 12 and the rollers 13 and the outer race 11 The inner peripheral surface, or the clutch cam 23 or the clutch lever 24 may be deformed or damaged. In this embodiment, since the spring 22C is interposed between the operating member 22 and the clutch cam 23, the operating knob 21 is operated while the roller 13 is biting between the outer race 11 and the inner race 12. Also, only the spring 22C is deformed, and deformation and breakage of the roller 13 and the like can be prevented. The clutch cam 23 can be rotated by the stored force of the spring 22C deformed in the non-wedge action direction at the stage when the biting state of the roller 13 is eliminated.

As described above, in the first embodiment, in order to prevent the handle shaft 6, which is a rotating part, from rotating in the other direction, the roller 13 in the annular holder 14 is switched to the non-wedge action position. When performing the operation, the operation knob 21 supported by the side plate 3
Since the engagement projection 17A in the annular holding member 14 can be moved out of the annular holding member 14 by a simple rotation operation, the playability at the time of switching to the wedge action position can be reduced and the operation can be performed quickly. No impact occurs when the reverse rotation is inhibited after the increase in the reverse rotation speed, which is caused by the delay in switching to the wedge action position, so that not only the reverse rotation prevention device itself can be prevented from being damaged, but also yarn breakage can be prevented. Therefore, it is possible to prevent troubles such as dislodging fish being taken in. Further, an annular holding body 14 for holding the roller 13 and an outer ring body 11 for restricting the outward movement of the roller 13 are provided so as to be rotatable integrally with the handle shaft 6 which is a rotating part. Since the inner ring body 12 to be combined is provided integrally with the frame body 2 which is a fixed portion, the regulating force and the regulating position at the time of wedge action can be accurately secured.

A reverse prevention device for a fishing reel according to a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, the reverse rotation preventing device is applied to a spinning reel. Spinning reel 51

As a result, a concave portion is formed, and the bottom portion 53A is fixed to the shaft cylinder 27. A groove 53a extending in the radial direction is formed in the bottom 53A of the rotor 53. On the other hand, a pair of arms (not shown) for supporting a bail (not shown) rotating around the spool is provided integrally with the cylindrical portion 53B. ,

When the handle is rotated, the force is transmitted to the pinion gear via a master gear (not shown), and the rotor 53 fixed to the cylinder shaft 27 integrated with the pinion gear rotates together with the cylinder shaft 27. At the same time, the spool shaft 29 reciprocates back and forth inside the cylindrical shaft 27 by a spool reciprocating mechanism (not shown), so that the spool can be moved back and forth, and the fishing line is uniformly wound on the spool.

Next, a one-way clutch according to a second embodiment will be described. One-way clutch is mainly outer ring 3
1, an inner race 32, a roller 33 serving as a rolling member, and an annular holder 34. FIG. 5 shows the spool shaft 2

The rotor 53 is disposed in the recess. The metal annular body 38 is formed concentrically with the rotation axis of the rotor 53, and is movable in the radial direction of the rotor 53 at the time of assembling by the engagement between the projection 38A and the groove 53a. The outer race 31 is fixed to the inner peripheral surface of the metal ring 38.
Therefore, the outer race 31 can rotate together with the rotation of the rotor 53. The inner peripheral surface of the outer race body 31 forms a regular octagonal cam surface. A reel housing 3 in which an outer race body 31 is fixed by a metal annular body 38 formed concentrically with the rotation axis of the rotor 53;
0 so that the molding accuracy of the rotor 53 or the reel housing 30 and the molding accuracy of the rotor shaft core and the rotor or the reel housing are roughened to improve productivity. In addition, the rotor 53 can be made of synthetic resin or the like, so that the weight of the product can be reduced.

From the front of the reel housing 30, the reel housing 3
0 and the cylindrical portion 30A extends coaxially with the shaft cylinder 27,
The distal end of 0A is provided integrally with the cylindrical portion 30A so as to face the cam surface of the inner race body 31 having a circular cross section. Therefore, a substantially annular guide slot S1 is provided between the inner ring body 32 and the outer ring body 31, but the width of the guide groove S1 in the radial direction from the axis of the shaft cylinder 27 is not constant. In the portion where the inner ring body 32 and the vicinity of the corner of the cam surface 31 face each other, the width of the guide slot S1 is the largest, and is larger than the diameter of the roller 33. In the portion where the center of the side of the cam surface on the inner peripheral side of the outer ring body 31 and the inner peripheral surface of the inner ring body 32 face each other, the width of the guide slot S1 is the smallest and smaller than the diameter of the roller 33.

That is, the annular holder 34 is rotatably fitted to the inner peripheral surface of the metal annular body 38 in advance. Since the annular holder 34 accommodates the roller 33 in advance, this allows the roller 33 and the annular holder 34 to be unitized with the metallic annular body 38, thereby simplifying the assembly operation.

The annular holding body 34 is formed with holding holes 34a at regular intervals in the circumferential direction so as to penetrate in the radial direction. A roller 33 serving as a rolling member is disposed in the holding hole 34a. The roller 33 is located within the holding hole 34a.
The annular holder 34 is movable in the radial direction, is movable in the circumferential direction together with the annular holder 34, and is immovable in the front-rear direction (axial direction) by the wall 34A defining the holding hole 34a. Is done. When viewed in the circumferential direction of the annular holder 34, a metal reinforcing member 35 made of a thin iron plate or the like is provided on one wall of the holding hole 34a that comes into contact with the roller 33. By arranging the metal reinforcing member 35, the annular holding body 34 itself can maintain its durability without being worn even if it is formed of a synthetic resin or the like, thereby simplifying the work of processing the product and reducing the weight of the product. Etc. can be achieved. Further, engagement holes 34b extending in the axial direction of the annular holder 34 are formed at regular intervals in the circumferential direction of the annular holder 34. As shown in FIG. 7, the engagement hole 34b has an inclined surface.

The roller 33 housed in the holding hole 34a is locked between the annular holder 34 and the metal annular body 38 in the wedge direction, that is, between the outer ring 31 and the inner ring 32. A spring body 36 for providing an elastic force in a direction in which the spring body 36 moves is provided. That is, the spring body 36 is provided so as to rotationally urge the annular holding body 34 in the X direction in FIG. 6 with respect to the outer ring body 31 to urge the roller 33 in the same direction. As described above, the annular holder 34 is provided so as to be rotatable by a predetermined angle with respect to the outer ring body 31, and is an elastic means for urging the roller 33 in the wedge action direction between the annular holder 34 and the metal annular body 40. Since the spring 36 is provided, the roller 33 is moved to the inner race 3 during the wedge action.
2 can be held at a position close to the position 2, and the operation accuracy can be improved. Further, unlike the first embodiment, it is not necessary to attach individual elastic means to each roller, so that the structure can be simplified.

A switching member 37 is slidably provided on the outer peripheral surface of the cylindrical portion 30A of the reel housing 30. Switching member 37
Is formed with a projection 37A extending forward, and is provided so as to be able to engage with the above-described engagement hole 34b of the annular holder 34. That is, when the inclined protrusion 37A moves rearward (to the right) in FIG.
Due to the positional relationship between the inclined surface 4b and the biasing force of the spring body 36, the annular holding body 34 rotates counterclockwise in FIG. 6, and when the inclined protrusion 37A moves forward in FIG. 6 against the urging force of FIG.
Rotate clockwise.

As in the first embodiment, the switching member 37
Is provided with a switching mechanism 40 behind. Switching mechanism 4
Reference numeral 0 includes an operation knob (not shown), an operating member 42, a clutch cam 43, and a clutch lever 44. The operation knob is
The operating member 42 is rotatably supported outside the reel housing 30, and the operating member 42 is connected to the operation knob in the reel housing 30 and penetrates the front wall of the reel housing 30 as shown in FIG. 5. doing. Further, as in the first embodiment, a disk portion 22A as shown in FIG.
A boss 22B and a spring 22C are provided.

The clutch cam 43 is located at a position immediately before the front wall of the reel housing 30.
It is provided rotatably around 0A. Its shape is the same as that of the clutch cam 23 shown in FIG. The clutch lever 44 is rotatable with respect to the switching member 37 and is not movable in the axial direction with respect to the switching member 37.
It is supported by. The shape of the clutch lever 44 is the same as that of the clutch lever 24 shown in FIG. Also, as shown in FIG. 7, the relationship between the clutch lever 44, the pin 26, and the coil spring 27 is the same as in the first embodiment.

FIG. 6 shows a state where the roller 33 is switched to the wedge action position. In this state, the rotation of an operation knob (not shown) causes the protrusion of the clutch cam 43 (2 in FIG. 4).
3A) does not match the clutch lever 44, and the clutch lever 44 is moved rightward in FIG. 7 by the urging force of the coil spring 27. Therefore, the switching member 37 also separates from the annular holder 34, and the inclined projection 37A of the switching member 37
Also moves in the direction of coming out of the engagement hole 14a of the annular holder 34, so that the annular holder 34 rotates counterclockwise by the urging force of the spring 36 in FIG. The roller 33 is held at the wedge action position described above.

In this state, by operating a handle (not shown), the rotor 53 is moved in the fishing line winding direction (forward rotation) indicated by the arrow X.
Is rotated, the roller 33 does not perform a wedge action because the roller 33 tends to relatively move in a direction in which the gap between the cam surface on the inner periphery of the outer race 31 and the outer periphery of the inner race 12 increases. As a result, the rotor 53 rotating integrally with the outer race 31 can be continuously rotated forward. However, when the handle is rotated in the reverse direction in order to rotate the rotor 53 in the fishing line payout direction (reverse rotation) indicated by the arrow X, the distance between the cam surface on the inner circumference of the outer race 31 and the inner circumference of the inner race 32 is reduced. Since the roller 33 tends to move in the direction, the rotor 53 integrated with the outer race body 31 cannot rotate in the reverse direction due to the wedge action of the roller 33, and therefore, the reverse operation of the steering wheel becomes impossible.

Next, when the operation knob (not shown) is rotated in the opposite direction, the clutch cam 43 is turned in the clockwise direction in FIG. 4 against the urging force of the coil spring 25 as described in the first embodiment. By rotating the clutch cam 43 so that the projection of the clutch cam 43 is aligned with the clutch lever 44, the clutch lever 44 rides on the projection, and the clutch lever 44 moves forward against the urging force of the coil spring 27. Accordingly, the switching member 37 connected to the clutch lever 44 advances, and the inclined projection 37A of the switching member 37 penetrates deeply into the engagement hole 34b of the annular holder 34, as shown in FIG. Due to this intrusion operation, the annular holding body 34 is
6 against the urging force of FIG. 6 until it reaches the non-wedge action position in FIG. Therefore, the roller 33 moves near the corner of the cam surface of the outer race body 31 in FIG. At the position after the movement of the roller 33, the distance between the circular outer peripheral surface of the inner race 32 and the inner peripheral surface of the outer race 31 is larger than the diameter of the roller 33, so that the rotor 53 integrated with the outer race 31 is forward / reverse. Rotation is not restricted in either direction.
That is, fishing line winding and feeding operations can be performed. in this way,
The roller 33 is switched to the wedge action position and the non-wedge action position together with the annular holder 34 by the intrusion / retreat operation of the inclined projection 37A, so that the switching operation can be executed reliably.
