PROBLEM TO BE SOLVED: To assure reliable opening and closing operation while preventing the erroneous operation of a power window when a drive circuit of the power window becomes wet due to ingress of water or dew condensation. SOLUTION: In ordinary time, a power window is closed or opened by driving a motor 3 by constituting a circuit via an opening relay Ro and a closing relay Rs by operating a first opening & closing switch Sd or a second opening & closing switch Sa in a state where the main switch Sm is connected to the first position P1 . If the drive circuit is wet due to ingress of water or dew condensation, both relays Ro, Rs may sometimes have an erroneous operation due to a leak current caused by the ingress of water or dew condensation but, if the second switch Sa is operated in a state where the main switch Sm is transferred to a third position P3 , a circuit not connected to both the relays Ro and Rs is constituted so that definite opening & closing can be assured while preventing the erroneous operation of the power window. |
