PROBLEM TO BE SOLVED: To provide an inexpensive wheel by reducing manufacturing cost of an inner sleeve used for an omni-wheel type wheel.SOLUTION: In a wheel, an inner hole 38 of a cylindrical body 40 provided in an inner sleeve 36 has a straight axis line X and a constant cross sectional shape. A shape and dimensions of the inner hole 38 are defined so that the cylindrical body 40 abuts on a peripheral surface on a radial outer side of a core body 32 in an intermediate part in an axial direction and abuts on a peripheral surface on a radial inner side of each core body 32 in both end parts in the axial direction.SELECTED DRAWING: Figure 7
【課題】オムニホイール式の車輪に用いられるインナースリーブの製造コストを低減し、安価な車輪を提供すること。【解決手段】インナースリーブ36に設けられる円筒体40の内孔38を、真直な軸線Xを有し且つ一定の横断面形状を有するものとし、円筒体40が軸線方向の中間部において芯体32の径方向外方の周面に当接すると共に軸線方向の両端部において各々芯体32の径方向内方の周面に当接するように、内孔38の形状及び寸法を定める。【選択図】図7
