The operation of the rolling type one-way clutch A is shown in FIGS. 1 and 3, and when the operation knob 36, the operation rod 30 and the switching member 31 are rotated to the positions indicated by the solid line in FIG. Since the lever 8a of the annular holding member 8 is rotated in the clockwise direction and the rod-shaped rolling member 28 is positioned in the free rotation range α and is in a non-operating state in which no wedge action occurs, the rotor 6 and the drive cylinder shaft 4 are positively moved. Rotation and reverse rotation are possible. Next, when the operation knob 36, the operation rod 30, and the switching member 31 are rotated and rotated to the position indicated by the chain double-dashed line in FIG. 3, the lever 8a of the annular holding member 8 is rotated counterclockwise. Since the rod-shaped rolling member 28 is brought into contact with the lever-shaped rolling member 28 to be in an operation state where it is positioned on the blocking surface β where rotation is blocked and a wedge action occurs, the rotor 6 and the drive cylinder shaft 4 are normally rotated against the spring 29.

When the reverse rotation of the rotor 6 is prevented, the operating knob 36, the operating rod 30, the switching member 31 and the annular holding member 8 are rotatably operated, and the rod-shaped rolling member indicated by a chain double-dashed line in FIG. 28 is abutted and positioned on the blocking surface β where rotation is blocked, and the operating state is switched to the wedge action. Fishing line
When 44 is fed and the rotor 6 is rotated counterclockwise in the reverse direction, the drive cylinder shaft 4 and the rotor 6 are rotated in the reverse direction. However, since the rod-shaped rolling member 28 is in contact with the blocking surface β where rotation is blocked, reverse rotation is blocked by the wedge action. Further, at this time, since the rod-shaped rolling member 28 has little play during reverse rotation due to the wedge action, the rotor 6 can be swiftly moved.
Reverse rotation is stopped.
