<p>PURPOSE:To prevent the occurrence of noise by providing an elastic material between an electric motor and the inner wall of a housing to store the motor. CONSTITUTION:An elastic material 159 such as sponge is set in a bent state on the housing 2 side of a motor case 137 supported by a housing 2'. When an electric current is supplied to an electric motor in the case 137, a wheel gear is turned through a worm, and the projection of the wheel gear comes into contact with an arm to move an operating lever 17 to locking or unlocking position. A door lock mechanism is operated through a link mechanism by the pin 10. In the case where a wide aperture is formed between the housings 2 and 2' or an aperture is formed in the case 137, the case 137 is moved by vibration during the opening or closing operation of the door to prevent the occurrence of anomalous noise.</p> |
