<p>PROBLEM TO BE SOLVED: To miniaturize a door lock driving device which can execute the both functions of an unlatch function and a closer function with a sigle motor 4, and at the same time, to provide the door lock driving device which is taken the safety corresponding to bite of fingers or the like into consideration. SOLUTION: The door lock driving device is constituted that a large reduction gear ratio of the rotational speed of the motor 4 is obtained by using reduction gears (the first and the second reduction gears), the unlatch function, which unlatches a door lock 1, and the closer function, which operates closer of the door lock 1, are separated in the direction of rotation of normal rotation and reverse rotation of the second reduction gear. By this, even during the closer operation by the rotation in the reverse rotation direction of the second reduction gear, when the motor 4 is rotated in the normal rotation direction after stopping the closer operation, the change-over from the closer operation stopped position to the unlatch operation can be executed.</p> |
