PURPOSE:To simplify a device in structure in reducing the number of parts and undo a lock as well as to prevent a gear noise from occurring by transmitting motor torque to a rocking member being connected to an output shaft directly from an intermediate gear via an elastic body. CONSTITUTION:A door lock driver is constituted of a pinion 2 being clamped to a turning shaft of a motor 1, an intermediate gear 3 being engaged with this pinion and a rocking member 7 being connected to an output shaft, and a spring 5 as an elastic body is set up on the gear free of rotation of its winding part with a countershaft 9 as the center. When an operated lever is operated and unlocking takes place by hand, the spring 5 rotates with movement of the rocking member 7, but in an interval between the spring 5 and an engaging projection 4, there is a rotational play angle of more than a turning angle of the spring 5 due to the movement of the member 7, whereby the spring is not engaged with this projection 4, so that the gear 3 is not rotated at all, thus unlocking is carried out with small operating force. |
