1. A cam clutch comprising: an inner race and an outer race that are coaxial and rotatable relative to each other; a plurality of cams circumferentially arranged at intervals between the inner race and the outer race; a biasing means biasing each of the plurality of cams so that each of the plurality of cams makes contact with the inner race and the outer race; and
an operating mode switch means including a cam attitude change part that is drivable independently of rotation of the inner race and the outer race to forcibly tilt the cams, wherein
a load support point is located radially between a load application point of the cam attitude change part on the cam and a distal contact point of the cam on a raceway that is one of the inner race and the outer race positioned on a radially distal side relative to the load application point, a radial distance between the load application point and the load support point being larger than a radial distance between the load support point and the distal contact point, and
the cams are tilted around the load support point as a center of rotation when the cam attitude change part moves.
