PROBLEM TO BE SOLVED: To provide an omnidirectional movement wheel capable of achieving smooth travel, an omnidirectional movement wheel pair and an omnidirectional movement vehicle comprising the same.SOLUTION: An omnidirectional movement wheel 10 of the invention comprises a rotation frame 30 which can rotate around an axle 20, and plural sets of roller units 40 on an outer periphery of the rotation frame. The roller unit comprises: a first roller 50 whose outer peripheral surface matches a curvature of a wheel outer peripheral circle whose center is the axle and formed into an almost barrel-shape; second rollers 60, 60 arranged on both sides of the first roller, whose outer peripheral surface matches a curvature of the wheel outer peripheral circle, whose diameter is reduced to a direction separated from the first roller and formed into an almost circular truncated cone shape; and third rollers 70, 70 arranged adjacent to the second rollers, whose outer peripheral surface matches to a curvature of the wheel outer peripheral circle, whose diameter is increased to a direction separated from the second roller, and which is formed into an almost circular truncated cone shape.SELECTED DRAWING: Figure 1
【課題】本発明は、滑らかな走行を実現することのできる全方向移動車輪、全方向移動車輪対及びこれを具えた全方向移動車両を提供する。【解決手段】本発明に係る全方向移動車輪10は、車軸20を中心として回動自在な回動枠30と、前記回動枠の外周に複数組のローラユニット40を配置してなる全方向移動車輪であって、前記ローラユニットは、前記回動枠に等間隔に配置され、外周面が前記車軸を中心とする車輪外周円の曲率と一致する略樽型形状の第1ローラ50と、前記第1ローラの両側に配置され、外周面が前記車輪外周円の曲率と一致し前記第1ローラから離れる方向に縮径する略円錐台形状の第2ローラ60,60と、前記第2ローラに隣り合って配置され、外周面が前記車輪外周円の曲率と一致し前記第2ローラから離れる方向に拡径する略円錐台形状の第3ローラ70,70と、を具える。【選択図】図1
