PURPOSE:To secure the superior floating-up preventing effect by forming the wall parts extending to a blade rubber side on the leeward side of a main lever which constitutes the upper edge of a wiper blade and forming air vent holes on the upper edge of the main levers continuous to the wall parts. CONSTITUTION:A primary lever (main lever) 2 is installed at the top edge of a wiper arm 1, and a secondary lever (sublever) 4 having yokes 3 supported at the both edges is supported at each edge part of the primary lever 2, and a blade rubber 6 is installed at the edge part of each yoke 3. Each wall part 2a, 4a, 3a extending to the leeward side is installed up to the part covering the upper edge of the blade rubber 6, at the outside parts of the both levers 2 and 4 which constitute the upper edge part of a wiper blade B and at the outside part of the yoke 3. Further, air vent holes 2c, 4c, and 3c are formed onto the upper walls 2b, 4b, and 3b which are continuous to the wall parts 2a, 4a, and 3a, respectively. |
