PURPOSE:To simplify the operation of a windshield wiper as well as to reduce its actual setting space, by installing a driving circuit for a windshield wiper motor to use both front and rear windows in common, while transmitting a driving signal to one side of window motors from the driving circuit via a dividing circuit. CONSTITUTION:When an INT switch 2 and an ignition switch 4 are turned on, a traveling contact inside a driving circuit 1 is changed over. And, a terminal at the earth side of a windshield wiper motor 22 used for a front window is connected to earth via a terminal N and the traveling contact of the driving circuit 1 whereby the motor 22 rotates. And, simultaneously an output signal is transmitted to a clock terminal CLK of a divider 60 of a dividing circuit 58 from a terminal P of the driving circuit 1. An output pulse of the divider 60 turns on a transistor 62 so that a contact 68 of a relay 64 is turned on as well. With this constitution, a rear window wiper motor 70 rotates as specified. |
