1. A cam clutch having a torque limiter function, comprising:
at least one pair of an inner ring and an outer ring that are coaxial with each other and rotatable relative to each other;
a plurality of cams disposed in a circumferential direction between the inner ring and the outer ring; and
biasing means for biasing the plurality of cams so as to come into contact with the inner ring and the outer ring, wherein
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 provided in a portion of the cam clutch other than cam receiving surfaces of the inner ring and the outer ring such that the contact of the inclination restricting portion with the locking portion limits the inclination of the cam to a position at which the cam transmits a predetermined torque between the inner ring and the outer ring to limit amount of transmitted torque between the inner ring and the outer ring.
