  • Patent number: 9174610
    Abstract: A wiper blade includes a wiper strip, a backing, a blade holder coupled to the wiper arm, and two opposed cases arranged at two longitudinal ends of the blade holder. The blade holder includes a blade holding portion, which surrounds a base portion of the wiper strip and the backing at a longitudinally central portion of the wiper strip and the backing. The blade holding portion restricts movement of the wiper strip and the backing in a direction orthogonal to the longitudinal direction. Each case includes a case holding portion that surrounds the base portion of the wiper strip and the backing. The case holding portion restricts movement of the wiper strip and the backing in a direction orthogonal to the longitudinal direction.
