A windshield wiper includes a connecting seat, two elastic plates, a wiper, two rubber protective hoods, two side covers, a shelter, and a connecting block. Thus, each of the elastic plates is snapped into the respective snapping plate of the connecting seat so that each of the elastic plates is mounted in the connecting seat in a snapping manner without needing the riveting process. In addition, each of the side covers has two locking posts each locked in the locking hole of each of the elastic plates so that each of the side covers is mounted on the elastic plates closely without needing an adhesive.
