PROBLEM TO BE SOLVED: To facilitate the escape of a driver by providing a submerged sensor, a melting fuse and the like in the control circuit of a window opening/closing motor, and not rotating the window opening/closing motor to a closing side, even if a vehicle submerges and leak current occurs. SOLUTION: When a vehicle falls into water by an accident, current flows in a submerged sensor 6, the fuse 7a of a prohibition part 7 is fused by the current to cut a connection path between the coil 4a of a closing relay and a direct current power source 13. Even if a transistor 4i flows into a base and operation is switched on by leak current, excitation current is prevented from flowing into the coil 4a of the closing relay. Thus, even if a control circuit 4 is submerged and malfunction is performed, a motor 1 is not driven falsely to the closing side. In the prohibition part 7, a coil, a relay, a switch and the like in addition to the fuse may be used. Thereby even if the vehicles submerges, malfunction is prevented, and the life of the drivers can be protected. |
