<p>PURPOSE:To permit stable performance to be kept for a long period of time by a method in which an electric motor, a worm gear, a wheel gear, and an operating lever which constitute an actuator are supported in a subhousing fixed to the lower part of the main housing. CONSTITUTION:A subhousing 2' is fixed to the lower part of the main housing 2, and an electric motor 26, worm gear 27 fixed to the motor 26 shaft, a wheel gear 18 engaged with the gear 27, and operating lever 17 to be coupled with the projection 45 of the gear 18, constituting an actuator to lock or unlock a door, are supported in the subhousing 2 '. The dimensional accuracy in the constitutional elements of the actuator is determined by a mold for forming the housing 2 ' and therefore, there is no influence from deviation in assembling with the main housing 2. The occurrence of damage and noise can thus be prevented.</p> |
