PROBLEM TO BE SOLVED: To facilitate on-off operation of braking of a caster.SOLUTION: An actuation switching mechanism of an actuation device is configured such that a part of a brake rod 22 for switching braking is projected from a brake device of a caster to the outside and the brake rod 22 is advanced or retreated to turn on or off and switch the operation of the brake device. A shaft 40 having an operation part 50 is rotatably supported on a furniture and is elastically biased, and an actuation member with one end mounted to the shaft 40 is arranged to be contactable with the brake rod 22. When the operation part 50 is pressingly operated by external force while overcoming the elastically-biasing force, the shaft 40 is rotated and is locked at a predetermined rotation angle, and when the operation part 50 is pressingly operated by external force again, the shaft 40 is unlocked to return to the previous position.SELECTED DRAWING: Figure 5

    【課題】キャスタの制動のオン・オフ操作を容易にする。【解決手段】作動装置の作動切換機構、キャスタの制動装置から制動の切り換えを行う制動ロッド22の一部を外部に突出させ、この制動ロッド22を進退動させて制動装置の作動をオン・オフさせて切り換えるよう構成され、家具に操作部50を有する軸40を回動自在に軸支して弾発付勢し、一端が軸40に取り付けられた作動部材を制動ロッド22に当接可能に配置している。操作部50が外力により弾発付勢力に打ち勝って押圧操作されると、軸40を回動させて所定の回動角度でロックし、操作部50が再び外力により押圧操作されると、軸40のロックを解除し元の位置に復帰させるようにした。【選択図】図5
