1. A single-cage cam clutch comprising plural sprags to be arranged between an outer ring and an inner ring, a retainer holding said sprags in place, and a spring guided by said retainer to urge said sprags in wedging directions, wherein:

  • said retainer comprises a cylindrical part provided with sprag windows, which serve to retain said sprags, and a flange extending from one of opposite ends of said cylindrical part in radial directions of said cylindrical part and provided with plural slits, and is formed of a resiliently-deformable material;

    said flange comprises large-diameter portions and small-diameter portions separated from each other by said slits; and

    said large-diameter portions of said flange are press-fitted in a flange-receiving slot formed in an inner peripheral wall of said outer ring by causing said large-diameter portions to flex owing to the resiliency of said retainer so that said large-diameter portions can be maintained in engagement with said flange-receiving slot.
