When an ECU 41 for wiper motor detects that a SP operation has been carried out in the midst of swinging motion of a wiper blade, the ECU 41 for wiper motor outputs a motor stopping signal to an ECU 42 for washer pump. When the ECU 42 for washer pump receives the motor stopping signal, the ECU 42 for washer pump stops a washer pump 30 even if an injection switch for jetting out washer fluid is on. In this manner, when a wiper blade is stopped from being swung for replacement of the wiper member, the pump for causing washer fluid to jet out is stopped. Therefore, it is possible to prevent the waste of washer fluid, and to further save washer fluid.
