<p>PURPOSE:To prevent a return spring from coming off and facilitate the work of assembling members by inserting the end portion of a return spring in a gear in the direction of thickness of a clutch member so as to support the spring, and pressing a plate to those members from outside. 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, a clutch output gear 24 and the like. The end portion of the return spring 23 is inserted in the direction of thickness of the roller 22 and supported therein. A plate 29 is pressed to the input gear 21 from outside the roller 22 and the return spring 23 and is calkingly fixed to the input gear 21 vie a hole 29a therethrough. The return spring 23 is thus prevented from coming off and also the work of assembling the members is facilitated.</p> |
