Abstract
A one-way clutch includes a C-shaped spring having one end thereof engaged by the inner ring and the other end abutting a roller at one end of a row of rollers that abut each other, thereby engaging the rollers with the outer ring and the inner ring. The inner ring has a radius at the engaging end of the cam surface opposed to the roller at the other end of the row of the rollers larger than its radii at the engaging ends of the cam surfaces opposed to the other rollers of the same row.
