To make compatible both the suppression of an increase of the turning torque of a wiper blade with respect to a wiper arm, and the suppression of a variation of a tip of the wiper blade.SOLUTION: A resin-made connecting member 30 comprises a connecting part 31 which is accommodated in an accommodation hole 24 formed at a first lever 21 of a wiper blade 20, and has slits 33 for releasing axial holes 32 into which a shaft 26 bridged between both sidewalls 25 of the accommodation hole 24 is fit, and a part of a peripheral wall 32a of the axial hole 32, and to which a U-shaped attachment part 14 arranged at a tip part of the wiper arm 10 is connected. The connecting member 30 has a pair of support parts 34 extending from both sides of the connecting part 31 in a width direction W, and supporting both side faces 14a of the attachment part 14 of the wiper arm 10. The pair of the support parts 34 are arranged at a side at which the slits 33 are formed in a height direction H of the connecting part 31, the side being a base end side of the wiper arm 10 with respect to the axial hole 32, and has an elastically-deformable arm part 35 which protrudes toward the base end side.SELECTED DRAWING: Figure 4
【課題】ワイパアームに対するワイパブレードの回動トルクの増大抑制と、ワイパブレードの先端の変動抑制との両立を図ること。【解決手段】樹脂製の連結部材30は、ワイパブレード20の第1レバー21に形成された収容孔24内に収容されるとともに、収容孔24の両側壁25に掛け渡された軸26が嵌め込まれる軸孔32及び軸孔32の周壁32aの一部を開放するスリット33を有し、ワイパアーム10の先端部に設けられたU字状の取付部14が連結される連結部31を備えている。連結部材30は、連結部31の幅方向Wの両側から延びるとともに、ワイパアーム10の取付部14の両側面14aを支持する一対の支持部34を有している。一対の支持部34は、連結部31の高さ方向Hにおいてスリット33が形成されている側であり、且つ軸孔32よりもワイパアーム10の基端側に設けられ、同基端側に向けて突出する弾性変形可能な腕部35を有している。【選択図】図4
