Abstract
Provided is a clutch device capable of reliably transmitting predetermined torque. Power is transmitted from an outer ring to a second gear through a first gear. The teeth of the first gear are formed so that the lines of the teeth are non-parallel to the center axis. The direction of axial force generated by the reaction force of the second gear and acting on the first gear is set to be the same as the direction of movement of the outer ring. When rollers engage with raceway surfaces and power is transmitted from the first gear to the second gear, the reaction force of the second gear promotes the movement of the outer ring in the axial direction. Predetermined torque can be reliably transmitted because axial pull-in force between an inner ring and the outer ring increases.
