Abstract
Abstract In a windshield wiper for vehicles, yoke members are directly fixed to an arm. At least one of the yoke members comprises two sections between which is loaded a spring so as to normally bias the two sections and therefore a blade toward the windshield. Alternatively, a spring may be loaded between the arm head and arm piece which may comprise two bar-shaped members. Even when the windshield is curved, the blade may be uniformly pressed against it. A number of pivotal connection members is reduced so that less noise is produced. Since a number of components is reduced, the assembly is much facilitated at less cost.
