To set a moving trajectory of a member to a prescribed moving trajectory, and to set a moving trajectory of a wiper to a prescribed moving trajectory.SOLUTION: A drive unit 16 comprises a wheel 36 having a plurality of first protrusions 50 which are rotatably supported, protrude toward the outside of a rotation radial direction, are formed into shapes larger than base end sides at tip sides in a protrusion direction, and aligned with intervals in a rotation peripheral direction. The drive unit 16 also comprises a rail 38 having a plurality of second protrusions 54 which protrude toward the wheel 36 side, are formed into shapes larger than base end sides at tip sides in a protrusion direction, and aligned with intervals. While the plurality of first protrusions 50 sequentially get out of clearances between the pair of second protrusions 54 after being sequentially engaged with the clearances between the pair of second protrusions 54, the wheel 36 rotates along the rail 38, and the wheel 36 relatively moves along the rail 38.SELECTED DRAWING: Figure 3

    【課題】部材の移動軌跡を所定の移動軌跡とする。ワイパの移動軌跡を所定の移動軌跡とする。【解決手段】駆動装置16は、回転可能に支持され、回転径方向外側へ向けて突出すると共に突出方向先端側が基端側よりも大きな形状に形成され回転周方向へ間隔をあけて配列された複数の第1突起部50を有するホイール36を備えている。また、駆動装置16は、ホイール36側へ向けて突出すると共に突出方向先端側が基端側よりも大きな形状に形成されかつ互いに間隔をあけて配列された複数の第2突起部54を有するレール38を備えている。複数の第1突起部50が一対の第2突起部54の間に順次係合した後に一対の第2突起部54の間から順次抜け出しながらホイール36がレール38に沿って回転して、ホイール36がレール38に沿って相対的に移動する。【選択図】図3
