AbstractA link rod for driving wiper blades is coupled to and driven by a crank arm by means of an eccentric bush, so that an effective length of the link rod can be changed. A stopper portion is provided on the link rod for maintaining, during a normal operation, the eccentric bush in such a position where the effective length is smallest. A driving mechanism including three gears meshing with each other drives the eccentric bush when a wiping operation should be stopped so that the eccentric bush is rotated and placed at a position where the effective length of the link rod becomes largest, whereby the wiper blades are held in concealed positions during the blades are out of operation.
