Wiper blade

Rotation of a tip side of a blade holder toward a windshield at or beyond a predetermined angle is regulated with respect to a wiper arm. A convex portion is formed at a portion of the blade holder opposing to an arm mounting member, and a concave portion is formed at a portion of the arm mounting member opposing to the blade holder, whereby engagement of the convex and concave portions admits rotation of a tip side of the wiper blade toward the windshield at or beyond a predetermined angle to be regulated with respect to the wiper arm. By such a structure, since contact between the wiper arm and the wiper blade is prevented, it is suppressed that a coating of the wiper arm or blade holder is peeled off to bring early its rusty, and that damages of both members make their wiping performance easily deteriorate.
