Clutch drive device and vehicle

A clutch driving device including an actuator for driving a clutch and a transfer mechanism that transfers, to the clutch, a rotation force output from the actuator, the clutch driving device comprising:

• a friction mechanism that generates a friction force in a direction opposite to a rotation direction of the rotation force, wherein
• the transfer mechanism includes
• an input shaft that receives the rotation force output from the actuator,
• an output shaft that outputs the rotation force to the clutch, and
• an intermediate member that transfers the rotation force from the input shaft to the output shaft,
• the friction mechanism includes
• a rotation body that rotates about an axis in response to the rotation force transferred by the transfer mechanism,
• a friction plate that generates the friction force by contact with the rotation body, and
• an elastic body that biases one of the rotation body or the friction plate relative to the other in an axial direction such that the rotation body and the friction plate are brought into contact with each other, the axial direction being a direction in which the axis extends, and
• one of the input shaft, the output shaft, or the intermediate member includes a rotation transfer member that rotates together with the rotation body and is disposed to be movable in the axial direction relative to the rotation body.
