A clutch drive device is configured to prevent a reverse assist force in an allowance area even without providing a canceling compensation spring. The clutch drive device includes a clutch; an actuator; a first solid of revolution 19, an actuation force transmission mechanism 15 that transmits a drive force of the actuator to the clutch to follow rotation of the first solid of revolution 19; and an assist spring unit 25 having one end pivotally supported and the other end abutting on the solid of revolution 19. An abutment structure in which the first solid of revolution 19 abuts on the assist spring unit 25 is configured so that an urge force of the assist spring unit 25 does not act in a direction of rotating the first solid of revolution 19 at least at one position in an allowance area in which the clutch is not disengaged even if the first solid of revolution 19 rotates.
