A one way clutch includes a tubular outer drive member formed of a thermoplastic resin and integrally formed with a torque transmitting member such as a gear or hand lever, a metal sleeve with a polygonal inside face located in the bore of and rotatable with the outer drive member, an integrally formed thermoplastic resin cage member projecting into the sleeve and having retainer spaces holding rollers engagable with respective sleeve polygonal faces, a coaxial shaft engaging the rollers which are spring biased to release positions in the wedge spaces delineated by the confronting shaft and sleeve surfaces and snap fastening means integrally formed with the cage and outer drive members locking the clutch in assembled condition. In one form the fastening means are snap interlocking annular groove and rib formed on the confronting faces of the cage and drive members and in another form the cage member includes a flange having coupling openings engaged by the barbed ends of resilient arms integrally formed with the outer drive member.

A one way clutch comprising an outer member integrally formed of a polymeric resin composition rotatable about a longitudinal axis and having formed therein a longitudinal cavity open at an end thereof, a sleeve of a relatively hard material located in said cavity and interlocked and rotatable with said outer member and having on its inside peripheral face a plurality of circumferentially spaced similarly directed circumferentially radially inclined wedge surfaces, an integrally formed cage member projecting into said cavity and including an outer base section and a plurality of circumferentially spaced inwardly directed longitudinal columns delineating retainer spaces registering with respective wedge surfaces, said cage and outer members having integrally formed therewith radially relatively resiliently separable complementary fastening means interlocking said members in assembled condition against relative longitudinal movement, a roller element disposed and circumferentially movable in each of said retainer spaces and a shaft coaxially registering with said cage member, the opposite faces of said roller elements confronting the surface of said shaft and respective sleeve wedge surfaces.
