An emergency electronic door lock apparatus is provided to improve convenience of user by using a rotatory member for rotating a rotatory force transmitter when emergency status is occurred. A locking member(102) is installed on an inner of a door and locks the door or releases the locking condition. An inner body(200) is installed on an inner of the door and contains a battery. An outer body(300) is installed on an external of the door and provided with a keypad(301) for opening the door on a front of the outer body(300). A control circuit is provided inside of the inner body(200) to control an operation of the locking member(102). A driving motor is provided inside the inner body(200) to be driven forwardly and backwardly by the control circuit. A decelerator is provided inside the inner body(200) to reduce rotatory force of the driving motor. A rotatory force transmitter is interlocked with the decelerator and axis-coupled to a locking member operation unit(103) to transmit the rotatory force of the decelerator to the locking member operation unit(103). An end of a forced rotatory member(205) is coupled to a central part of the rotatory force transmitter and the other end is projected to the front of the inner body(200) to rotate the rotatory force transmitter by force based on breaking the other end when emergency status is occurred.
