PURPOSE: An electric lock having an electric driver for operating a dead bolt is provided to simplify a structure and reduce the manufacturing cost by operating simultaneously the dead bolt and a latch bolt without using a complicated interlocking device. CONSTITUTION: A handle is installed in a main lock box. A sub lock box is installed at a back side of the main lock box. A dead bolt and a latch bolt(50) are installed in the sub lock box. A locking shaft(44) is installed rotatably on an extended line of a handle shaft. A driving hub(76) is installed at one side of the locking shaft in order to operate the dead bolt. An axial hub is installed at the other side of the locking shaft. The first driving leg(18) and the second driving leg(20) are fixed to the handle shaft, are projected from the main lock box, and are disposed in both sides of the lock shaft. A motor(10) is installed in the sub lock box. A screw bar is connected to an output shaft of the motor. A cam plate member(86) is guided into the sub lock box and includes a screw hole. A clutch lever(98) is pivoted on a front end of the axial hub. A lever pressing spring is used for pushing a hydraulic arm part to a lateral part of the locking shaft. An interlocking lever is pivoted on the sub lock box. A drawing arm part is formed at the interlocking lever.
