Abstract: A windshield wiper assembly for a car includes a wiper unit connected with a support arm. The wiper unit includes a blade having a mounting seat, a wiper connected with the blade, a movable bracket movably mounted in the mounting seat, at least one support pin secured on the mounting seat and extended through the movable bracket, and at least one pair of elastic members each biased between the mounting seat and the movable bracket. The movable bracket is biased between the elastic members. Thus, the movable bracket is moved relative to and deflected from the mounting seat when the wiper unit is driven by the support arm to reduce the frictional resistance. In addition, the elastic members provide a shock-absorbing function between the mounting seat and the movable bracket to eliminate vibration produced during movement of the wiper unit.
