ABSTRACT:
A wiper device for a vehicle, has a sub-arm turnably supported by a vehicle body through a supporting shaft provided in a base end thereof. An arm shaft is turnably provided in a tip end of the sub-arm and a base end of a wiper arm is fixed to the arm shaft. The supporting shaft has a cylindrical shape and a drive shaft is inserted into the cylindrical supporting shaft. One end of the drive shaft on the side of the sub-arm, is connected to the arm shaft by a gear mechanism and the other end of the drive shaft is connected to a drive source and is reciprocally turned thereby. To the outer surface of the supporting shaft is fixed a Geneva gear. On a circular plate turnably connected to the drive source is an eccentrically provided pin. When the arm shaft is outside a predetermined turn angle range, the pin is fitted in a notch of the Geneva gear to turn the supporting shaft and when the arm shaft is within a predetermined turn angle range, the pin is disengaged from the notch of the Geneva gear to stop the supporting shaft from turning.
