To provide an omni-directional wheel which can realize achievement of both of increasing a force received by each roller and weight saving at a high level.SOLUTION: An omni-directional wheel comprises: a rotary part 30 of which an outer peripheral surface is formed by a plurality of rollers 40, 50, and which rotates around a rotation axis; and a plurality of support parts 60 which are arranged in a circumferential direction of the rotary part, are attached to the rotary part respectively, and support the rollers at the rotary part. The rollers have a plurality of first rollers 40 and a plurality of second rollers 50, and the first rollers and the second rollers are alternately arranged in the circumferential direction. Each support part has a first arm 70 which supports one end side in an axial direction of the corresponding first roller of the plurality of first rollers, and a second arm 80 which supports the other end side in the axial direction of the corresponding first roller. The corresponding second roller of the plurality of second rollers is supported by one first arm and the other second arm of two support parts which are adjacent to each other in the circumferential direction.SELECTED DRAWING: Figure 1
【課題】各ローラが受けられる力を大きくすることと軽量化の両立を高いレベルで実現可能な全方向車輪を提供する。【解決手段】外周面が複数のローラ40,50により形成され、回転軸線周りに回転する回転部30と、回転部の周方向に配列されると共に、回転部にそれぞれ取付けられ、回転部にローラを支持する複数の支持部60と、を備え、ローラは、複数の第1ローラ40と複数の第2ローラ50とを有し、第1ローラと第2ローラとは周方向に交互に並んでおり、各支持部は、複数の第1ローラのうち対応する対応第1ローラの軸方向の一端側を支持する第1アーム70と、対応第1ローラの軸方向の他端側を支持する第2アーム80と、を有し、周方向に隣り合う2つの支持部のうち一方の第1アームと他方の第2アームとによって、複数の第2ローラのうち対応する対応第2ローラが支持されている。【選択図】図1
