Abstract
A one-way clutch apparatus comprises an inner ring, an outer ring disposed to be coaxial with the inner ring and rotatable relatively thereto, a plurality of concave grooves formed in an axial direction in an inner peripheral surface of the outer ring, and block bearings engaging the respective concave grooves and keeping an interval between the inner ring and the outer ring. The concave groove takes such a configuration that a surface including two or more circular arc surfaces connects side surfaces extending in radial directions to a bottom surface extending in a peripheral direction, which configure the concave groove.
