A windshield wiper structure for a vehicle which has a wiper stroke adjusting machanism. The wiper structure includes a main lever (9) connected through a first pin with a wiper actuating rod (13) and secured through a second pin (2) to the wiper arm (4). The wiper actuating rod (13) drives the main lever (9) to swing about an axis of the second pin (2). A first eccentric shaft (16) is provided about the first pin and a second eccentric shaft (24) is provided about the second pin (2). The first eccentric shaft (16) is connected with the wiper actuating rod (13) so that a rotation of the first eccentric shaft (16) causes a relative movement between the main lever (9) and the wiper actuating rod (13). A second eccentric shaft (24) is provided about the second pin (2) and connected through an interconnecting lever (25) with the first eccentric shaft (16). A stroke adjusting (22,23) mechanism is provided for effecting a rotation of the second eccentric shaft (24).
