Abstract
A one-way clutch allows unlocking torque input to a movable retainer to be made low, thereby enabling downsizing of an external apparatus that inputs unlocking torque to the movable retainer. The one-way clutch includes an inner ring, an outer ring, first rollers used to transmit torque between the inner ring and the outer ring provided in an annular space between the inner ring and the outer ring, and fixed retaining portions of a fixed retainer and a movable retaining portions of a movable retainer that are arranged alternately. The one-way clutch also includes second rollers provided between the movable retaining portions and the first rollers adapted to transmit unlocking torque from the movable retaining portions to the first rollers and the inner ring as the movable retaining portions move in a clockwise direction.
