The cam clutch includes: a plurality of cams disposed in a circumferential direction between at least one pair of an inner ring and an outer ring that are coaxial with each other and rotatable relative to each other; and biasing means for biasing the plurality of cams so as to come into contact with the inner ring and the outer ring. Each of the cams includes an inclination restricting portion that restricts inclination of the cam in an engaging direction by coming into contact with a locking portion that is provided in a portion of the cam clutch other than cam receiving surfaces of the inner ring and the outer ring.
