Abstract
The wipers of a windshield wiper are oscillated by a drive shaft driven by a wiper motor. A disc-type contact base member is securely mounted on the drive shaft to carry thereon two electrically conductive plates each of which is contactable with a pair of stationary contacts. When an electrical connection is established between the pair of stationary contacts, a washer pump supplied with electric current is driven to eject a washer liquid through nozzles onto the surface of a windshield. The conductive plates are so located that the electrical connection between the pair of stationary contacts is established only during time periods in which the wiper blades move in both 'go' and 'return' directions from their starting positions to positions which are immediately in front of the positions at which the wiper blades would be struck by the washer liquid being ejected from the nozzles.
