To provide a sphere driving type movement device capable of suppressing ununiformity of resistance acting on each rotor of a caster, and a caster provided on the same.SOLUTION: There is provided a sphere driving type movement device 10 comprising: casters 12, 13, 14 attached to a base mechanism 11; and drive spheres 18, 19, 20 which receive rotation force of a drive source in a state of being contacted by the casters 12, 13, 14 and rotate, and roll on a travel plane G, the sphere driving type movement device moving on the travel plane G. The casters 12, 13, 14 comprise: a plurality of rotors contacting the drive spheres 18, 19, 20; and a support member for rotatably supporting the plurality of rotors, in a state in which an angle with respect to the base mechanism 11, is variable. By force acting to each rotor from the drive spheres 18, 19, 20 following deviation of the drive spheres 18, 19, 20 from a reference position, the support member is varied in the angle with respect to the base mechanism 11, and a state in which all rotors contact the drive spheres 18, 19, 20, can be maintained.SELECTED DRAWING: Figure 2

    【課題】キャスタの各回転体に作用する抗力の不均一性を抑制可能な球体駆動式移動装置及びそれが具備するキャスタを提供する。【解決手段】ベース機構11に取り付けられたキャスタ12、13、14と、キャスタ12、13、14が接触した状態で、駆動源の回転力を与えられて回転し走行面G上を転動する駆動球体18、19、20とを有して、走行面G上を移動する球体駆動式移動装置10において、キャスタ12、13、14は、それぞれ駆動球体18、19、20に接する複数の回転体と、ベース機構11に対する角度が可変する状態で、複数の回転体を回転自在に支持する支持部材とを備え、駆動球体18、19、20が基準位置からずれるのに伴い駆動球体18、19、20から各回転体に作用する力によって、支持部材は、ベース機構11に対する角度が変わり、複数の回転体の全てが駆動球体18、19、20に接した状態を維持する。【選択図】図2
