WIPER DEVICE AND WIPER SYSTEM

To greatly reduce restrictions in mounting.SOLUTION: A wiper device 30 includes: a wiper member 32 that is supported by a supporting shaft 20 provided in a vehicle at a base end portion of a wiper arm 34 and can be rotated about the supporting shaft 20; a pair of wheels 58 and 64 that are aligned in a longitudinal direction of the wiper member 32 and are supported by the wiper arm 34 so as to rotate about a pair of wheel shafts 62 and 66 having, as an axis direction, a rotation axis direction of the wiper member 32; a motor 52 that is supported by the wiper arm 34 and reciprocatingly rotation-drives the one wheel 58; and a rotation rail 70 which is formed in a long shape, is supported by the vehicle at one end portion in a longitudinal direction so as to rotate about a rail shaft 78 having, as the axial direction, the rotation axis direction of the wiper member 32, and is curved when viewed from the rotation axis direction, changes a curvature radial of the curve in the longitudinal direction, and is sandwiched between the pair of wheels 58 and 64, and in which the pair of wheels 58 and 64 is rotated in the longitudinal direction by the reciprocating rotation-driving.SELECTED DRAWING: Figure 4 【課題】搭載上の制約を大幅に低減する。【解決手段】ワイパ装置３０は、車両に設けられた支持軸２０にワイパアーム３４の基端部が支持され、支持軸２０回りに回動可能とされるワイパ部材３２と、ワイパ部材３２の長手方向に並んで配置され、ワイパ部材３２の回動軸線方向を軸線方向とする一対のホイール軸６２、６６回りに回転可能にワイパアーム３４に支持された一対のホイール５８、６４と、ワイパアーム３４に支持され、一方のホイール５８を往復回転駆動するモータ５２と、長尺状に形成され、ワイパ部材３２の回動軸線方向を軸線方向とするレール軸７８回りに回動可能に長手方向一端部が車両に支持され、上記の回動軸線方向から見て湾曲しており、当該湾曲の曲率半径が長手方向で変化すると共に、一対のホイール５８、６４の間に挟持され、上記の往復回転駆動により一対のホイール５８、６４が長手方向に転動する回動レール７０と、を備えている。【選択図】図４
