PROBLEM TO BE SOLVED: To forcibly opening-drive an opening-closing body even in the case of the occurrence of an abnormality by connecting a power source to a motor for opening-closingly driving an opening-closing body so as to forcibly opening- drive it according to an operation. SOLUTION: A terminal of an opening operation switch DOWN-SW is connected to a connecting line between a terminal (d) of a motor 56 and a solenoid coil of a relay 57, and a terminal (c) of this switch is connected to the terminal (a) of a relay 53. In addition, in the case where an open switch signal has been outputted from a communication IC 51, the terminal (a) of the relay 53 is switched from GND to a power source. When the down switch DOWN-SW is operated, an excitation current is supplied to the internal coil of the relay 57 through the terminals (b), (a) of the switch DOWN-SW to separate the contact of the relay 57 from the terminal (c). Thus a power source for making the motor 56 closing-drive a window is cut off, and the window is therefore forcibly opening-driven. |
