To perform switching between a brake state and a brake release state of a caster device with a relatively simple structure without having a switch structure provided on wheels themselves.SOLUTION: A caster device includes: caster frames 30; legs 36 and wheels 40 supported in a displaceable manner in a vertical direction by the frames 30, respectively; a change-over switch 7; and change-over mechanism parts 70 which switch ground states by drive force of motors 72 between a first ground state S1 in which only the legs 36 are brought into contact with a floor surface F and a second ground state S2 in which only the wheels 40 are brought into contact with the floor surface F. The change-over mechanism parts 70 make the legs 36 move upward by bringing the wheels 40 into contact with the floor surface F when switching from the first ground state S1 to the second ground state S2, and make the wheels 40 move upward by bringing the legs 36 into contact with the floor surface F when switching from the second ground state S2 to the first ground state S1.SELECTED DRAWING: Figure 5
【課題】車輪自体に特殊な切替構造を設けることなく、キャスタ装置の制動状態と制動解除状態との切替えを比較的簡単な構成で行う。【解決手段】キャスタ装置は、キャスタフレーム30と、当該フレーム30に各々上下方向に変位可能に支持された脚部36及び車輪40と、切替スイッチ7と、モータ72の駆動力により、脚部36のみが床面Fに接地する第1接地状態S1と車輪40のみが床面Fに接地する第2接地状態S2との間で接地状態を切り替える切替機構部70とを含む。切替機構部70は、第1接地状態S1からから第2接地状態S2への切替えの際には、車輪40を床面Fに接地させてから脚部36を上方へ移動させ、第2接地状態S2から第1接地状態S1への切替えの際には、脚部36を床面Fに接地させてから車輪40を上方へ移動させる。【選択図】図5
