Abstract
To provide a cam clutch that has a simple configuration and is capable of preventing a cam posture changing portion from being strongly sandwiched between a cam, an outer ring and an inner ring, and of tilting a cam efficiently without causing deformation of the cam posture changing portion and the cam themselves. A cam clutch includes an operation mode switching mechanism, wherein the operation mode switching mechanism includes a cam posture changing portion. A plurality of cams each includes inner and outer ring abutment curved surfaces provided at positions facing an outer peripheral surface of the inner ring and/or an inner peripheral surface of the outer ring, and a lateral abutment surface. The lateral abutment surface is connected to ends of the inner and outer ring abutment curved surfaces, and is formed inside of the cam relative to a virtual extension curved surface.
