Cam clutch

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,
• wherein the inclination restricting portion restricts the inclination of the cam in the engaging direction when a torque higher than a predetermined torque is applied during transmitting a torque equal to or lower than the predetermined torque between the inner ring and the outer ring through engagement of the cam between the inner ring and the outer ring to cause slipping between a cam surface of the cam and the cam receiving surface of the inner ring or the outer ring to limit amount of transmitted torque.
