PROBLEM TO BE SOLVED: To provide a power window device capable of lowering a window glass when a lowering switch is turned on even if the circuit of the power window device is wetted with water. SOLUTION: When a circuit of a power window device 10 is soaked with water so that the circuit leaks, both relay coils 21, 23 are excited. In such a condition, on turning on a lowering switch 28, a transistor TR2 becomes low potential at the base by a circuit L1 including a diode D3 to be disabled from on-operation. In such a condition on operating an automatic down switch 16d, the relay coil 23 becomes the same potential at both terminals by a circuit L2 including a diode D1 to inhibit excitation of the relay coil 23. Accordingly, only the relay coil 21 is excited so that a relay contact 25 is operated so that a driving motor M is rotated normally to lower a window glass. |
