ABSTRACT:
When a spool rotates in a retraction direction, a guide pin of a lock member presses against an inner wall of a groove portion with a pressing force in the same direction as a centrifugal force. As a result, friction between an outer circumferential portion of the guide pin and the inner wall of the groove portion increases, a V-gear is held by the guide pin, and rotation of the V-gear in the retraction direction relative to the spool is suppressed. Further, the V-gear, which is pressed by a pressing force at the inner wall of the groove portion, presses against a shaft portion of a torsion shaft with a pressing force in the same direction as the above-described pressing force when the V-gear attempts to move in the direction of action of the above-described pressing force. Accordingly, friction between an inner circumferential portion of the V-gear and an outer circumferential portion of the shaft portion increases and, as a result, rotation of the V-gear in the retraction direction relative to the spool is suppressed.
