Abstract
A clutch driving device includes: a spring that is deformable in a circumferential direction when seen in an axial direction to thereby generate a force in the circumferential direction; a first projection disposed at one end of the spring; an output gear that rotates in an disengaging direction or an engaging direction of the clutch; and a pin that is provided to the output gear to be rotatable together with the output gear and contacts the first projection to thereby transfer the elastic restoring force to the output gear. A contact point between the first projection and the pin moves toward an axis of the spring at least once when seen in the axial direction of the spring in a case where the output gear rotates in a direction in which the elastic restoring force of the spring decreases.
