To reduce concerns about extension/contraction operation in a wiper device causing a wiper arm and a wiper blade to perform combined wiping operation including oscillating operation and extending/contracting operation.SOLUTION: A vehicle wiper device 2 causes a first wiper arm 35 (and a first wiper blade) to perform combined wiping operation including oscillating operation and extending/contracting operation. A regulation section 51 for regulating a movable range to a component on an operating route to the first wiper blade in an extension/contraction mechanism that is, in this case, a second driving crank arm 14 is provided to regulate the extending/contracting operation of the first wiper arm 35 (and a first wiper blade).SELECTED DRAWING: Figure 2 【課題】ワイパアーム及びワイパブレードに対して揺動動作と伸縮動作とを含む複合払拭動作を行わせるワイパ装置において、伸縮動作に係る懸念事項を低減する。【解決手段】車両ワイパ装置２は、第１ワイパアーム３５（及び第１ワイパブレード）に対して揺動動作と伸縮動作とを含む複合払拭動作を行わせる。伸縮機構における第１ワイパブレードまでの駆動経路上の構成部材、この場合第２駆動クランクアーム１４に対して可動範囲を規制する規制部５１が設けられ、第１ワイパアーム３５（及び第１ワイパブレード）の伸縮動作の規制が図られる。【選択図】図２
