Abstract
A large-diameter retainer and a small-diameter retainer for retaining sprags are mounted between the inner member as the driving member and the outer ring as the driven member. The large-diameter retainer is coupled with the inner member with a play in the direction of rotation. A switch spring is attached to one end of both of the retainers. To the other end, a turning effort imparting mechanism is coupled through a one-way clutch. The outer ring is coupled with the output shaft with a play in the direction of rotation which is set to be larger than the abovesaid play. When the inner member rotates, the large-diameter retainer will rotate first to tilt the sprags. After the play in the direction of rotation has disappeared, the coupling member between the outer ring and the output shaft will rotate. Thus, the sprags are always brought to correct ready-to-engage positions.
