Cam clutch unit

A cam clutch unit comprising a plurality of cams and a plurality of rollers disposed between an inner ring and an outer ring coaxially provided capable of relative rotation, a cage ring having a plurality of pocket portions which regulate relative movement in a circumferential direction of the cams and the rollers, and an annular spring which urges the cams, wherein

• the cams have an engagement stepped portion capable of engagement with the spring;
• the cage ring has an end-part circumferential annular portion continuing in the circumferential direction on an end surface in the axial direction;
• a surface of one of the pocket portions adjacent to the corresponding roller in the circumferential direction is formed having a shape which regulates movement of the roller to the outer ring side and the inner ring side and has a claw portion capable of insertion of the roller from the outer ring side or the inner ring side by elastic deformation,
• wherein the cage ring has a plurality of hook portions which regulate movement of the annular spring in the axial direction, and
• the hook portion has a hook bottom portion which regulates the movement in a radial direction of the annular spring.
