Most power window can not detect the existence of human beings, to cause some critical accident occasionally. The device comprises a sensor (5), a power window control system (10), and window operating switches (SW1,SW2). If the sensor detect any living creature during closing operation consequently power window control system stop the closing operation by sending a high signal to second transistor (Q2). Consequently the first transistor becomes off status of the motor (M) stopped because power supply is stopped. This invention is expected to decrease chorking accident by power-window.
