To improve aerodynamic characteristics while securing good wiping performance.SOLUTION: A wiper blade 10 includes a wiper lever assembly 20 having a tournament structure. The wiper lever assembly 20 has a pair of movable covers 60 provided both sides in a longitudinal direction of a main lever 22 to which a wiper arm is connected to a central part in the longitudinal direction. On both sides in the longitudinal direction of the main lever 22 and each of the movable covers 60, fin surfaces 46 and 84 descending toward a vehicle front side are formed, and a main storage chamber and a movable storage chamber 86 that are opened on a wiping surface side are formed. A pair of yoke levers 96 which are stored over each of the main storage chambers and each of the movable storage chamber 86 are rotatably connected to the main lever 22 and each of the movable covers 60. In each of the main storage chambers, each of the movable storage chambers 86 and each of the yoke levers 96, the height dimension on the rear side is more enlarged from that on the front side.SELECTED DRAWING: Figure 5

    【課題】良好な払拭性能を確保しつつ、空力特性を向上させる。【解決手段】ワイパブレード10は、トーナメント構造のワイパレバーアッセンブリ20を備えている。このワイパレバーアッセンブリ20では、ワイパアームが長手方向中央部に連結されるメインレバー22の長手方向両側に、一対の可動カバー60が設けられている。メインレバー22の長手方向両側及び各可動カバー60には、車両前方側へ向かって下り勾配のフィン面46、84が形成されると共に、払拭面側に開口したメイン収容室及び可動収容室86が形成されている。また、各メイン収容室内と各可動収容室86内とに亘って収容された一対のヨークレバー96が、メインレバー22及び各可動カバー60に対して回動可能に連結されている。そして、各メイン収容室、各可動収容室86及び各ヨークレバー96が、前部側よりも後部側で高さ寸法を拡大されている。【選択図】図5
