PROBLEM TO BE SOLVED: To provide a lock release mechanism allowing to continue operation of the lock release mechanism in a specified time, and to continue released condition of a lock in a specified time even if energizing of a main switch is stopped. SOLUTION: The lock release mechanism 1 is connected to a locking mechanism through a cable 15 for releasing locking of the locking mechanism by pulling the cable 15 electrically. The lock release mechanism 1 comprises the main switch 2 operated by the hand, a motor 3 driven by energizing the main switch 2, a conversion gear mechanism 4 for converting an output direction of the motor 3, a conversion means 5 for converting rotating motion to reciprocating linear motion, a slider 6 to which the cable 15 is connected to make linearly reciprocate, and a limit switch 7 which can energize the motor 3 through a parallel circuit different from a current-carrying circuit of the main switch 2. Electricity to the limit switch 7 is cut off when the slider 6 is in a neutral position. On the other hand, energized condition is maintained while the slider 6 reciprocates once, and the slider 6 is held in a full-stroke position in a specified time. COPYRIGHT: (C)2009,JPO&INPIT
