A front end of the elastic member is supported on the intermediate shaft, and a rear end of the elastic member is supported on the clutch block. The clutch block includes: a gear; a friction plate; and a nut. The gear rotates relative to the friction plate and the nut, in response to a driving force of the motor for driving the gear being greater than a sum of a friction force between the gear and the friction plate and a friction force between the gear and the nut.
