<p>PURPOSE:To absorb noise caused by impact of connection of a clutch and also prevent members from damaging each other by forming in the guide wall of a prime mover member and in the transmission portion of a driven member respective slits capable of being elastically deformed so as to provide cushioning portions. CONSTITUTION:The clutch mechanism of an actuator using a motor is formed by a lever drum 19, a clutch input gear 21, a roller 22, a return spring 23 and a clutch output gear 24, etc. A slit 21e capable of being elastically deformed is formed in the sectorial portion of the roller guide wall 21a of the clutch input gear 21 to provide a cushioning portion 21c. When the clutch input gear 21 is connected to the clutch output gear 24 the gears are cushioned by the cushioning portion 25f of the clutch input gear 21 and the cushioning portion 24c of the clutch output gear 24 so as to absorb noise caused by impact.</p> |
