Abstract: A spacer for a windshield wiper includes an anchoring member, a cylindrical shaft, a biasing device, a bracing stand, and a retaining device. The anchoring member is to be mounted on the wiper blade seat and has a shaft accommodation hole. The shaft is inserted into the hole and is rotatable relative thereto but is not movable in an axial direction. The shaft includes an enlarged head exposed outwardly of the hole and is formed with a radially and outwardly projecting pivot pin that extends into a bearing hole in the bracing stand, thereby mounting the bracing stand on the shaft. The biasing device is sleeved on the shaft to bias the latter to rotate in a clockwise direction. The retaining device retains the bracing stand against rotation by the biasing device once the lower portion of the bracing stand is moved toward the windshield wiper to abut against the windshield so as to space the windshield wiper from the windshield against the urging action of the wiper arm.
