To provide a wheel holding device which holds a wheel including an annular core body and a plurality of free rollers rotatably supported by the core body.SOLUTION: A wheel holding device 1 which holds a wheel 4 including an annular core body 2 and a plurality of free rollers 3 rotatably supported by the core body has a center member 40 with an outer periphery part that is extendable in a radial direction. The outer periphery part of the center member urges an inner peripheral part of the wheel in the radial direction so that the center member holds the wheel. The center member includes: a chuck 42; a plurality of bases 43 which are movably supported by the chuck in the radial direction to constitute the outer peripheral part of the center member; and a plurality of urging members 44 which urge the respective bases in the radial direction against the chuck.SELECTED DRAWING: Figure 1

    【課題】 環状の芯体と芯体に回転可能に支持された複数のフリーローラとを有する車輪を保持するための車輪保持装置を提供する。【解決手段】 環状の芯体2、及び芯体に回転可能に支持された複数のフリーローラ3を有する車輪4を保持する車輪保持装置1は、径方向に伸縮可能な外周部を有する中心部材40を有する。中心部材の外周部が車輪の内周部を径方向外方に付勢することによって、中心部材が車輪を保持する。中心部材は、チャック42と、チャックに径方向に移動可能に支持され、中心部材の外周部を構成する複数のベース43と、チャックに対してベースのそれぞれを径方向外方に付勢する複数の付勢部材44とを有してもよい。【選択図】 図1
