PURPOSE:To simplify a relay in structure as well as to improve a degree of reliability ever so better, by replacing a relay switching function for driving a wiper to operate at an intermittent position of a wiper switch with a partial transistor. CONSTITUTION:A wiper relay circuit 8 is provided with a first relay RL1 to be operated by an intermittent signal out of a T terminal of a wiper amplifier 7 and a second relay RL2 for wiper drive use to be operated at an intermittent position of a wiper switch 1. And, a transistor Tr, where a signal corresponding to operation of the second relay is inputted, is installed in position between an auto-stop contact 22 of a wiper motor circuit 2 and a second relay coil RC2. This transistor Tr performs a switching function for the second relay RL2. |
