Abstract
A wiper device has a center bore provided at a wiper blade, a supporting shaft disposed in the center bore and a connecting hole provided at a leading end portion of the wiper arm. The supporting shaft has first and second diameter portions at a circumference thereof and a diametric length of the second diameter portion is smaller than that of the first diameter portion The connecting hole is provided at a circumference thereof with an opening whose chord length is larger than the diametric length of the second portion but smaller than the diametric length of the first portion. The wiper blade may be attached to and detached from the wiper arm by making the second diameter portion correspond to the opening, but the wiper blade may not be detached from the wiper arm in a normal use of the wiper device by rotating the wiper blade relatively to the wiper arm till a position where the second diameter portion does not correspond to the opening in the connecting hole.
