Abstract
A one-way clutch includes a retainer ( ), a spring ( ), and sprags ( ) which are provided in pockets of the retainer and those of the spring in a pivotable manner and forced by tongue-like flaps formed in the spring in a direction in which the sprags ( ) are to be locked. A peripheral maximum width (La) of an outer cam surface of the sprag ( ) and a peripheral maximum width (Lb) of an inner cam surface are greater than a circumferential width (Lp) of the pocket of the retainer ( ). Further, a width (Lc) of the sprag ( ) in the direction of inclination is made smaller than a circumferential width (Lp) of the pocket of the retainer ( ).
