To provide a wiper arm energization member which can reduce a rotation region around a drive shaft.SOLUTION: A wiper arm energization member F comprises: a drive shaft 11 which is reciprocated around a first axis X1 by a drive unit K; a tilting component 13 which is so supported at a tip of the drive shaft 11 as to be tiltable around an axis X2 having such a positional relationship as to cross the first axis X1, and is connected to a wiper arm WA; a lower support member 15 which is so supported at an intermediate part of the drive shaft 11 as to be rotatable around a third axis X3 along the second axis X2; an upper support member 16 which is so supported to the tilting component 13 as to be rotatable around a fourth axis X4 parallel to the third axis X3; and a compression coil spring 19 is so located that the drive shaft 11 is inserted therein, is supported by the lower support member 15, and applies energization force to the upper support member 16.SELECTED DRAWING: Figure 1

    【課題】駆動軸周りの回動領域を小さくすることができるワイパアーム付勢部材を提供すること。【解決手段】ワイパアーム付勢部材Fは、駆動装置Kにて第1軸線X1中心に往復回動される駆動軸11と、駆動軸11の先端部に第1軸線X1と交差の位置関係にある第2軸線X2中心に傾動可能に支持されワイパアームWAと連結される傾動部材13と、駆動軸11の中間部に第2軸線X2に沿った第3軸線X3中心に回動可能に支持された下側支持部材15と、傾動部材13に第3軸線X3と平行な第4軸線X4中心に回動可能に支持された上側支持部材16と、内側に駆動軸11が挿通されるように配置され下側支持部材15に支持されて上側支持部材16に付勢力を付与する圧縮コイルばね19とを備える。【選択図】図1
