Abstract
A windshield wiper device including a blade rubber, a backing holding the blade rubber in place, a support metal fixture including support claws for supporting the backing, an arm supporting the metal fixture, a spring loading the arm such that the blade rubber is forced against the windshield of a vehicle, and drive means connected to the arm for moving the arm, the metal fixture, the backing and the blade rubber in oscillating movement. The spacing interval between the adjacent two support claws is maximized at opposite end portions of the blade rubber and becomes smaller in going toward the center thereof, and a higher load is applied to the support claws near the central portion of the blade rubber than to the support claws near the opposite ends thereof, to thereby effectively avoid separation of the blade rubber from the surface of the windshield.
