Claims

[Claims for Utility Model Registration] In a wiper blade having a rubber for wiping a windshield whose end portion has a larger curvature than the center portion, a lip portion in contact with the windshield exists at a distance from the lip portion, respectively. It consists of a rubber body and a neck part that connects the rubber body and the lip part in a tiltable manner, and the lip inclination angle formed by the axis of the rubber body and the axis of the lip part is on the side of the end of the windshield. A wiper blade having rubber, characterized in that a lip inclination angle when the wiper blade moves toward the center of the windshield is smaller than a lip inclination angle when the wiper blade moves toward the center of the windshield.
