To provide a wiper blade manufacturing method that can suppress increase of kinds of components while allowing a plurality of kinds of blade lengths to be set.SOLUTION: Appearance constituting members arranged at an upper part side of a blade rubber to constitute integrated appearances in a longitudinal direction have three-way split constitution of first lever members as center constituting parts and wing members as side constituting parts at both sides, which is constituted by commonalizing the first lever members as the center constituting parts and the wing members as the side constituting parts with each other in length kind with respect to a plurality of wiper blades that are prepared for each predetermined length difference D. When lever lengths of the first lever members as the center constituting parts are defined as L and wing lengths of the wing members as the side constituting parts are defined as W, a relational expression of [2 W≥L≥1.4 W] is satisfied so as to keep good balance of lengths between both constituting members. By combining the plurality of center constituting parts with the side part constituting parts which are set respectively with length differences corresponding to multiple of a half of the predetermined length difference D, setting of wiper blades with lengths in a longitudinal direction suitable for an object to be wiped is performed.SELECTED DRAWING: Figure 2

    【課題】複数種類のブレード長の設定を可能としながら、部品種類の抑制を図ることのできるワイパブレードの製造方法を提供する。【解決手段】ブレードラバーの上部側に配置されて長手方向に一体的な外観を構成する外観構成部材は、中央構成部である第1レバー部材と両側の側部構成部であるウィング部材との三分割構成をなす。所定長さ差D毎に複数種類用意されるワイパブレードに対して中央構成部である第1レバー部材及び側部構成部であるウィング部材の長さ種類の共通化を図って構成する。中央構成部である第1レバー部材のレバー長をL、側部構成部であるウィング部材のウィング長をWとしたときの関係「2W≧L≧1.4W」を満足して両構成部材の長さバランスを良好としつつ、所定長さ差Dの1/2の倍数の長さ差でそれぞれ設定された複数の中央構成部と側部構成部とを組み合わせて、払拭対象に適した長手方向長さのワイパブレードの設定が行われる。【選択図】図2
