To provide a vehicle wiper device that broadens a front-passenger-seat-side wiping range of a wind shield glass in order to secure a wider field of view on the front-passenger-seat side.SOLUTION: In a case where entry into a traffic intersection and a left turn at the intersection are detected on the basis of positioning by a GPS device 96 and signals from a direction indicator switch 54 and a steering angle sensor 98, an output shaft 32 of a wiper motor 18 is normally rotated to move a front-passenger-seat-side wiper blade 28 from a lower inversion position P2 to an upper inversion position P1P. During this period of time, an amount of operation of an extending/contracting mechanism 120 is changed from 0 to a predetermined amount, thereby increasing a distance between a pivot shaft 42 which is a fulcrum of a front-passenger-seat-side wiper arm 24 and the leading end of the front-passenger-seat-side wiper blade 28. In addition, before the front-passenger-seat-side wiper blade 28 reaches the upper inversion position P1P, the amount of operation of the extending/contracting mechanism 120 is changed from the predetermined amount to 0, thereby decreasing the distance between the pivot shaft 42 and the leading end of the front-passenger-seat-side wiper blade 28.SELECTED DRAWING: Figure 1

    【課題】助手席側の広い視界を確保すべく、ウィンドシールドガラスの助手席側の払拭範囲を拡大する車両用ワイパ装置を提供する。【解決手段】GPS装置96による測位、方向指示器スイッチ54及び操舵角センサ98からの信号に基づいて車両の交差点への侵入及び当該交差点での左折を検知した場合に、ワイパモータ18の出力軸32を正回転させて助手席側ワイパブレード28を下反転位置P2から上反転位置P1Pへ移動させている間に、伸縮機構120の作動量を0から所定作動量まで変化させて助手席側ワイパアーム24の支点であるピボット軸42と助手席側ワイパブレード28の先端部との距離を拡大すると共に、助手席側ワイパブレード28が上反転位置P1Pに達するまでに伸縮機構120の作動量を所定作動量から0に変化させてピボット軸42と助手席側ワイパブレード28の先端部との距離を縮小する。【選択図】図1
