PURPOSE: An oil extractor is provided to process a signal of a back-lashing switch in a control unit and to reversely rotate a motor for preventing the motor from overloading. CONSTITUTION: An oil extractor comprises a main body, a motor(200), a first gear, a second gear, a screw(500), and an oil extracting unit. The first gear is integrally formed to a housing and is installed to a rotary shaft of the motor. The second gear is integrally formed to one side of the screw and receives power by the first gear. The screw is driven by the second gear and is vertically installed with respect to the rotary shaft. The oil extracting unit is positioned to the other side of the screw. A control unit receives a signal of a back-lashing switch and reversely rotates the motor.
