The clutch yoke 57 has a semicircular engaging portion 57a that engages with the constricted portion 32b of the pinion gear 32. On a side surface of the clutch yoke 57 facing the clutch cam 56, an inclined surface (not shown) on which the cam protrusions 56a and 56a run
When the clutch cam 56 rotates counterclockwise in FIG. 11 and the inclined surface rides on the cam projections 56a, 56a, the clutch yoke 57 moves to the clutch off position on the right side in FIG. Is descended from the cam projections 56a, 56a, and is urged by the coil spring 61 to return to the clutch-on position. In conjunction with the movement of the clutch yoke 57, the pinion gear 32 moves in the spool axial direction, and the clutch mechanism 21 switches between the clutch off state and the clutch on state.

The clutch return mechanism 58 includes a clutch cam 5
6, a return claw 59 rotatably connected to the connecting portion 56c.
And a toggle spring 62 for urging the return claw 59. The return pawl 59 is guided by the side plate 9 by the rotation of the clutch cam 57, and is ratchet teeth 88 of the ratchet gear 88.
The position moves to a position where it comes into contact with “a” and a position away from it. The toggle spring 62 holds the return claw 59 at two positions.

In this clutch return mechanism 58, when the clutch mechanism 21 is brought into the clutch off state by the pressing operation of the clutch lever 17, the clutch return mechanism 58 is guided by the side plate 9 and advances to a position where it comes into contact with the ratchet teeth 88a. In this state, when the handle shaft 30 is rotated in the yarn winding direction by operating the handle 2, the clutch shaft 56 is moved to a position where the handle shaft 30 is pressed and separated by the ratchet teeth 88a, and the clutch cam 56 is rotated clockwise in FIG. To the clutch-on state.

The casting control mechanism 24
It has a plurality of friction plates 51 arranged so as to sandwich both ends of the spool shaft 20, and a braking cap 52 for adjusting the holding force of the spool shaft 20 by the friction plates 51. The left friction plate 51 is mounted in the spool support 13.

As shown in FIGS. 3 and 5, the centrifugal brake mechanism 25 includes a rotating member 66 fixed to the spool shaft 20 so as to rotate integrally with the spool 12, and a circumferentially spaced apart rotating member 66. It has a cylindrical slider 67 arranged and movably mounted in the radial direction, and a brake liner 68 fixed to the inner peripheral surface of the ring portion 14 and capable of contacting the slider 67. The rotating member 66 has a disk portion 66a arranged on the outer peripheral side of the bearing portion 15, and the disk portion 66a is spaced apart in the circumferential direction by, for example, six concave portions 66b.
Are formed. In each recess 66b, two pairs of opposing locking projections 70a, 70b are formed at intervals in the radial direction. The locking projections 70 a are formed on the outer peripheral portion so as to protrude from each other, and are projections for preventing the slider 67 from coming off. The locking projection 70b is formed on the inner peripheral side of the locking projection 70a, and is a projection for preventing the slider 67 from contacting the brake liner 68. A guide shaft 69 extending in the radial direction is radially arranged on the bottom surface of the concave portion 66b. The slider 67 is movably guided by the guide shaft 69.

The slider 67 is a cylindrical member, and has a larger diameter than the other portions at the inner peripheral end thereof, and the locking projections 70a, 70a.
b has a flange portion 67a to be locked. When the spool 12 rotates, the slider 67 contacts the brake liner 68 by centrifugal force to brake the spool 12. At this time,
If the flange portion 67a goes over the locking projection 70b and is located on the inner peripheral side of the locking projection 70b, the flange portion 67a contacts the locking projection 70b and cannot contact the brake liner 68 even when centrifugal force acts. By switching the radial position of the slider 67, the braking force of the centrifugal brake mechanism 25 can be adjusted.

[Spool attaching / detaching operation] The fishing line is entangled with the spool 12 due to backlash or the like.
When detaching the reel 2 from the reel body 1, the first side cover 6 is opened to open the opening 8a of the side plate 8.

To open the first side cover 6, first, the swing shaft 34 is removed from the nut 40 by turning the nut 40 counterclockwise. When the swing shaft 34 comes off the detachable nut 40, the swing shaft 34 moves leftward in FIG. 4 by the urging force of the coil spring 35, and the first side cover 6 also moves leftward. Then, the first side cover 6 swings around the swing shaft 34 by its own weight, and the first side cover 6 opens to the open position. FIGS. 1 and 5 show a state in which the first side cover is opened. When the first side cover 6 is opened, the spool support 13 is exposed. Opening 1 in this state
6a, put a finger on the slider 67 of the centrifugal brake mechanism 25.
When the position in the spool radial direction is switched, the braking force can be adjusted. That is, when the slider 67 is disposed on the inner peripheral side with respect to the locking projection 70b, the slider 67 cannot contact the brake liner 68, and the braking force is reduced accordingly.

When the first side cover 6 is opened, the spool supporting portion 13 is turned counterclockwise by pinching the operation convex portion 16 with a finger. Then, the spool support 13 is disengaged from the side plate 8, and the opening 8a is exposed to the outside. In this state, the spool 12 can be removed by pinching and pulling out the spool shaft 20.

When the spool 12 is mounted, the spool 12 is mounted in the reel body 1 and then the spool support 13
Is attached to the side plate 8 and the first side cover 6 is closed. At this time, the cover main body 33 is manually swung toward the closed posture side, and further pressed against the side plate 8 side. When the detachable nut 40 is turned clockwise in this state, the tip of the swing shaft 34 is screwed into the detachable nut 40, and the first side cover 6 is attached to the side plate 8 to be in the closed position.

[Reel Operation and Operation During Actual Fishing] When performing casting, the clutch lever 17 is pressed downward. Then, the clutch plate 55 moves counterclockwise in FIG. At this time, the clutch plate 55
Moves inside the guide portion 9g in a state where the floating is prevented by the positioning pins 9e. When the clutch plate 55 moves, the clutch cam 56 rotates counterclockwise in conjunction therewith, and the clutch yoke 57 moves to the outer clutch off position in FIG. As a result, the pinion gear 32 constituting the clutch mechanism 21 moves outward in the axial direction, and enters the clutch off state. In this clutch-off state, the spool 12 is in a free rotation state, and when casting is performed, the fishing line is vigorously fed out of the spool 12 due to the weight of the tackle.

When the device has landed, the handle 2 is rotated in the line winding direction. Then, the ratchet gear 88 rotates in the yarn winding direction (clockwise in the figure), and the ratchet pawl 89 swings around the positioning pin 9d outside the ratchet gear 88 by the action of the control piece 89a, and comes into contact with the guide shaft 54. I do. As a result, the ratchet claw 89 does not come into contact with the ratchet gear 88 at the time of winding the yarn, and a click sound due to contact between the ratchet gear 88 and the ratchet gear 88 does not occur at the time of winding the yarn. Further, when the ratchet gear 88 rotates in the line winding direction, the ratchet teeth 88a abut on the tip of the return claw 59 and press the return claw 59 backward. Then, the return claw 59 retreats beyond the dead center of the toggle spring 62 and is urged by the toggle spring 62 to the separation position side. In conjunction with this movement, the clutch cam 56 rotates clockwise in FIG. 11, the clutch yoke 57 moves to the clutch-on position by the urging force of the coil spring 61, and the clutch mechanism 21 enters the clutch-on state. For this reason, handle 2
Is transmitted to the spool 12, and the spool 12 rotates in the line winding direction.

When the handle shaft 30 rotates in the yarn winding direction, the rotation is transmitted to the screw shaft 4 via the gear members 63a and 63b.
6 and the screw shaft 46 rotates. When the screw shaft 46 rotates, the fishing line guide portion 47 reciprocates in the spool axis direction, and the fishing line is uniformly wound around the spool 12.
