Title: CLUTCH UNIT AND VEHICLE
Abstract:
A clutch unit that can respond to wear of a torque transmission member is obtained by means of a different configuration from those of wear compensation devices proposed in the past. A clutch unit 17 comprises a clutch 13 having a clutch spring 28, an electric motor 50 that generates actuating driving force for actuating the clutch 13, an output shaft 63 which transmits the actuating driving force to the clutch 13 and to which elastic return force of the clutch spring 28 is inputted as clutch reaction force, and a spring 71 that inputs to the output shaft 63 assist force to assist the actuating driving force. When the clutch 13 is switched from a connected state to a switched state, the assist force is inputted to the output shaft 63 before the clutch reaction force is inputted, and when the clutch 13 is switched from the switched state to the connected state, the assist force reaches zero after the clutch reaction force has reached zero.
