Abstract
A one-way clutch for switching a power transmitting state and a power transmission interrupting state between an inner ring member and an outer ring member. At a plurality of circumferential portions of one of the inner ring member and the outer ring member, there are formed cam faces between the circumference of the one of the inner and outer ring members for forming wedge-shaped spaces which are narrowed in one circumferential direction. These cam faces are made to have a higher hardness than that of rollers which are individually arranged in the wedge-shaped spaces. As a result, the cam faces are suppressed from wear as the time elapses, and the wedge angle of the wedge-shaped spaces is kept substantially constant.
