To provide an omnidirectional movement wheel in which a rotation body being a tire has long life and laterally rotates smoothly, a foreign matter does not enter a sliding part, travel vibration and rotation noise are low, and appearance is preferable.SOLUTION: In an omnidirectional movement wheel 10, a rotation body 60 of which rotation axis is flexible is a tire, and a plurality of support rings having a core material 40 inserted to an inner diameter of the rotation body 60 are inserted. In the omnidirectional movement wheel 10, the core material 40 has an outer shape in which a plurality of short cylinders are continuously contacted with each other in a ring shape, a part of both ends of a small diameter ring 53 is inserted to an end part of a large diameter ring 52 so that an interval between adjacent support rings is made small, a region where the rotation body 60 cannot be supported by the inner diameter is almost eliminated to prolong the life of the rotation body 60, a position of the support ring with respect to the core material 40 is restricted by a lock piece 45 in a rotatable manner to eliminate strong contact between support rings to achieve smooth lateral rotation, and a high elastic material layer is provided in the inner diameter of the rotation body 60.SELECTED DRAWING: Figure 2
【課題】タイヤである回転体が長寿命、かつ、横行回転が滑らかで、摺動部への異物浸入がなく、走行振動や回転騒音が低く、見栄えの良い全方向移動車輪を提供する。【解決手段】回転軸が可撓性をもった回転体60をタイヤとし、回転体60の内径に芯材40を挿入した複数の支持リングを挿入してなる全方向移動車輪10において、芯材40は複数の短い円筒をリング状に連接した外形をもち、支持リングは小径リング53の両端の一部を大径リング52の端部に挿入することで隣接する支持リング間の隙間を小さくし、回転体60が内径からの支持を受けられない領域をほとんど無くすことで回転体60の寿命を延ばし、支持リングは回転可能の状態でロックピース45によって芯材40に対する位置を拘束して支持リング同士の強い接触を無くすことで滑らかな横行回転とし、回転体60の内径に高弾性材の層を設ける構成とする。【選択図】図2
