PROBLEM TO BE SOLVED: To provide a safety locking device of a door opening and closing mechanism for opening and closing the door of an aircraft, which is simple in structure and manufactured easily and at a low cost, and allowed to unlock the door in case of emergency requiring unlocking. SOLUTION: This safety locking device includes a control unit 10, an actuator 1 for operating locking mechanisms 18, 5, 6, 7, 9 and automatic recovery mechanisms 8a, 8b. The control unit 10 operates the actuator 1 in response to transmission of a designated signal, whereby the actuator 1 causes the locking mechanism to move to the locking position. The recovery mechanisms 8a, 8b automatically cause the locking mechanism to move the unlocking position when unlocking is needed. COPYRIGHT: (C)2004,JPO
