PROBLEM TO BE SOLVED: To provide a water-resistant power window which detects water penetrating into a water-resistant power window device and immediately changes a state to a motion for a flooding condition when it detects water. SOLUTION: In this water-resistant power window provided with a first series circuit comprising a first switch 1 and a first relay 2, a second series circuit comprising a second switch 3 and a second relay 4, a control IC 12, a wiring substrate mounting constituting parts a motor 11 is driven to one way to close the window by impressing the first relay 2 when the contact of the first switch 1 is changed over, and the motor 11 is driven to the other way to open the window by impressing the second relay 4 when the contact of the second switch 3 is changed over. The power window is also provided with a submergence-detecting element comprising a semiconductor detection element 14 connected in between an onboard electric source 13 and a detection terminal 8 of the control IC 12 and parallel submergence-detection conductors 15 connected in between the control end of the semiconductor detection element 14 and the earthing terminal and erected on the wiring substrate. When the submergence- detection element detects submerging condition, the semiconductor detection element 14 is switched on and an electric source voltage is output from the first terminal 1 and the second terminal 2 of the control IC 12. |
