Wiper apparatus

摘要

A wiper apparatus includes a wiper blade pivotable between a waiting position and an upwardly turning position. The wiper blade has first and second blade holding members disposed in alignment. Mounted to the first and second blade holding members is a blade rubber for wiping a curved windshield. Each blade holding member has a non-pivotal member and a pivotal member which are disposed in alignment. The pivotal member is pivotally connected via a pin to the non-pivotal member. The blade holding member further includes a twisting member. The twisting member has a sub-arm and a cam connected to the sub-arm. The sub-arm is designed to cause the cam to pivot in such a manner that the pivotal member pivots in a lateral direction of the wiper blade in response to the pivotal movement of the wiper blade. The pivotal movement of the pivotal member twists the blade rubber. The thus twisted blade rubber has its opposite ends disposed on the windshield at right angles thereto. As the wiper blade pivots between the waiting position and the turning position, the opposite ends of the blade rubber maintains a perpendicular relation to the windshield.
