PURPOSE: An enhanced door locking device is provided to prevent the generation of wrong operation with respect to the device by including a touch-sensitive switch arranged on the indoor side of an enhanced door. CONSTITUTION: A speed reducing motor operates based on a current applied according to the controlling signal of a controlling device. A linear movement unit(58) is in connection with the rotary shaft(57) of the speed reducing motor and converts the rotation movement of the speed reducing motor into a linear forwardly and backwardly movement. If the linear movement unit forwardly and backwardly moves, a locking unit forwardly and backwardly moves to be inserted into a fixed latch or be released from the fixed latch.
