To provide a cam clutch capable of preventing unwanted jamming of cams and switchable between operation modes with little force, thereby allowing size reduction. The cam clutch includes an inner race, an outer race, a plurality of cams, and a biasing means biasing the plurality of cams. The plurality of cams include first cams and second cams that have different engaging directions. The cam clutch further includes a frictional resistance generating means for generating friction resistance between a component adapted to tilt the first cams or second cams in the engaging direction, and the inner race and/or outer race when the first cams and second cams are simultaneously lifted off and separated from the raceways of the inner race and/or outer race during switching of operation modes.
