Cam clutch

A cam clutch comprising:

• an outer race and an inner race that are coaxially provided to be capable of relative rotation with respect to each other;
• and
• a plurality of cams arranged in a circumferential direction between the outer race and the inner race,
• the plurality of cams including a first cam and a second cam that are engaged with the outer race and the inner race in mutually different directions,
• the cam clutch further comprising:
• an operation mode switching mechanism that acts on at least one of the first cam and the second cam to switch an operation mode,
• the outer race or the inner race including an outer race main body or an inner race main body, and a first contact surface member and a second contact surface member that have cam contact surfaces respectively which come into contact with the first cam and the second cam,
• the first contact surface member and the second contact surface member being provided at different positions in a rotation axis direction and configured to be independently movable in the circumferential direction relative to the outer race main body or the inner race main body,
• the outer race main body or the inner race main body having a first movement restricting portion and a second movement restricting portion that restrict the movement of the first contact surface member and the second contact surface member in respective locking directions.
