A door locking and releasing part includes a main motor and is configured to apply a torque to the catch part through the main motor. An emergency door releasing part is provided with an auxiliary motor and is contacted with the door locking and releasing part by operation of the auxiliary motor. An inside emergency operating lever is connected with an inside handle installed at the vehicle door and is configured to receive an operation force of the inside handle to rotate and apply torque to the catch part through the emergency door releasing part and the door locking and releasing part.
