| 摘要 |
A freewheel (33) basically has an inner tubular member (51), an outer tubular member (52) rotatably mounted on an inner tubular member (51) with a clutch pawl (54) selectively connecting the outer and inner tubular members (52,51) together. A pawl-retracting member (56) is disposed between the outer and inner tubular members (52,51) with the pawl-retracting member (56) frictionally engaged with the internal circumferential surface of the outer tubular member (52) to rotate with the outer tubular member (52) between a pawl-retracting position in which the pawl-retracting member (56) maintains the clutch pawl (54) in a disengagement position and a pawl-releasing position in which the pawl-retracting member (56) releases the clutch pawl (54) to move to an engagement position. |
