Abstract
In a structure in which a middle portion of a wiper blade is pivoted to a leading end portion of a wiper arm via a pivot substantially orthogonal to an arm length direction so as to freely oscillate, and a supporting member supporting a portion closer to a wiper shaft than the middle portion of the wiper blade is provided in the wiper arm, the structure reduces a sliding resistance which occurs due to a movement of the wiper blade toward and away from a window surface. A stabilizer has an upper piece portion and a pair of side piece portions, a supporting concave portion supporting a wiper blade in an outward fitting manner is formed, and a plurality of ribs which extend toward the window surface are formed on inner surfaces of the side piece portions, thereby being in linear contact with outer surfaces of side piece portions of a support receiving body which is fitted to a first lever terminal end portion of the wiper blade.
