Abstract: A cam clutch unit includes a plurality of cams and a plurality of rollers disposed so as to be aligned in a circumferential direction between an inner ring and an outer ring, a cage ring having a plurality of pocket portions which regulate relative movement in a circumferential direction of the cam and the roller, and an annular spring which urges the cam, in which the cam has 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, the pocket portion 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.

Abstract: Provided is a cam clutch unit for which the rotational resistance of rollers can be reduced, the rollers can be arranged at optimum locations, and the weight can be reduced.
The cam clutch unit includes: a plurality of cams and a plurality of rollers aligned in a circumferential direction between an inner ring and an outer ring; a cage ring that includes a plurality of pocket portions that restrict relative movement of the cams and the rollers in the circumferential direction; and an annular spring that biases the cams, the cams each include an engagement portion that is engageable with the spring, the pocket portions that accommodate the rollers are provided at positions not interfering with the spring in an axial direction, and are arranged in a circumferential direction in a different manner on two sides relative to the spring.
