To provide a moving body with a caster which hardly falls down even if inclined to any directions, and can suppress an unintentional start of movement.SOLUTION: A moving body with a caster comprises at least three wheel parts, and at least one of the three wheel parts is a free caster which is constituted so as to be turnable with a turning axis substantially vertical to a floor face as a center. The free caster is constituted so that a grounding position of a wheel and the turning axis are separated from each other by a prescribed distance in an upper face view of the moving body with the caster, and the free caster comprises an energization mechanism for generating an energization force so as to maintain an orientation of the free caster at a prescribed orientation at non-grounding. The prescribed orientation is set so as to maximize an area of a support polygon with grounding positions of the wheels of at least the three wheel parts as apexes, respectively.SELECTED DRAWING: Figure 1

    【課題】キャスタ付き移動体が、どの方向に傾斜しても倒れ難く、意図せずに動き出すことを抑制できるキャスタ付き移動体を提供する。【解決手段】少なくとも3つの車輪部を備え、前記少なくとも3つの車輪部のうちの少なくとも1つは、床面と実質的に垂直な旋回軸を中心に回動自在に構成された自在キャスタである、キャスタ付き移動体であって、前記自在キャスタは、前記キャスタ付き移動体の上面視において、車輪の接地位置と前記旋回軸とが所定の距離だけ離れて構成され、非接地時に、当該自在キャスタの向きを所定の向きに維持するように付勢力を発生させる付勢機構を備え、前記所定の向きは、前記少なくとも3つの車輪部における車輪の接地位置をそれぞれ頂点とする支持多角形の面積を最大化するように設定されている。【選択図】図1
