PROBLEM TO BE SOLVED: To solve the problems of conventional emergent unlocking devices of electronic locks wherein the mechanism is complicated and the number of parts is increased and accordingly troubles are liable to occur, and also a product price is soared. SOLUTION: A pair of plates opposed to each other are fixed by holding at a specified interval with a spacer interposed therebetween. A screw bar and a guide bar are installed between the plates. The emergent unlocking device comprises a movable member into which the screw bar and the guide bar are inserted and an operating rod having one end engaged with a part of the movable member and the other end pivotally supported on one plate. The screw bar is engaged with a speed reduction output gear driven by a motor. The screw bar is rotated by the speed reduction output gear to move the movable member for synchronously pivotally moving the operating rod. The operating rod is engaged with the manual bolt member operating element of an electronic lock. COPYRIGHT: (C)2009,JPO&INPIT
