ABSTRACT:
A wiper device in which the swing angle of a blade set narrower or smaller during a high speed travel of a vehicle. Thus, in spite of a high speed travel of the vehicle, there is no fear that the upper limit of the blade exceeds a side edge of the vehicle window due to wind pressure on the blade.
