PROBLEM TO BE SOLVED: To provide a vehicular wiper device capable of setting a driving speed of a wiper arm to be a proper speed even near an inversion position.SOLUTION: A vehicular wiper device 2 drives first and second wiper arms 35 and 17 via a link mechanism including first and second drive crank arms 13 and 14 having base ends fixed to positively/negatively rotatable rotating shafts 11a and 12a of first and second motors 11 and 12. The first and second motors 11 and 12 are set to positively/negatively rotate in an angle range that does not include a dead point where the rotating shafts 11a and 12a cannot be rotated even when an external force is applied to the first and second wiper arms 35 and 17 in a link mechanism.SELECTED DRAWING: Figure 2

    【課題】反転位置近傍においてもワイパアームの駆動速度を良好な速度とすることができる車両ワイパ装置を提供すること。【解決手段】車両ワイパ装置2は、正逆回転可能な第1及び第2モータ11,12の回転軸11a,12aに基端部が固定された第1及び第2駆動クランクアーム13,14を含むリンク機構を介して第1及び第2ワイパアーム35,17を駆動する。第1及び第2モータ11,12は、リンク機構において第1及び第2ワイパアーム35,17に外力を加えても回転軸11a,12aを回転させることができない死点を含まない角度範囲で正逆回転されるように設定される。【選択図】図2
