Abstract
A vehicle window regulating apparatus is designed to move a window glass in a door on the side of a passenger seat up and down by operations of a remote contol switch installed on the door on the side of a driver seat. A relay is provided on a power supply line for supplying electric power to a motor in the door on the passenger seat side. This relay and the remote control switch are connected by way of a signal line and is of a diameter smaller than that of the power supply line. With operations on the remote control switch, switching signals are supplied to the relay via the signal line, and the relay is thereby turned on and off so as to supply electric power to the motor via the power supply line, so that the window glass is moved upward or downward. In the prior art apparatus, the motor on the passenger seat side is remote-controlled via the power supply line, but the present invention performs the remote control of the motor on the passenger seat side and can therefore achieve a reduction of power supply loss.
