ABSTRACT:
A windshield wiper structure for a vehicle which has a wiper stroke adjusting mechanism. The wiper structure includes a main lever connected through a first pin with a wiper actuating rod and secured through a second pin to the wiper arm. The wiper actuating rod drives the main lever to swing about an axis of the second pin. A first eccentric shaft is provided about the first pin and a second eccentric shaft is provided about the second pin. The first eccentric shaft is connected with the wiper actuating rod so that a rotation of the first eccentric shaft causes a relative movement between the main lever and the wiper actuating rod. A second eccentric shaft is provided about the second pin and connected through an interconnecting lever with the first eccentric shaft. A stroke adjusting mechanism is provided for effecting a rotation of the second eccentric shaft.
