The present invention relates to a cushioned rotational caster device for a chair, which comprises: a fixed body installed and fixed to a lower part of each of multiple legs vertically installed on a chair; and a rotational body hinged to the fixed body to rotate and having a driving ball, wherein a spring is installed between the fixed body and the rotational body, so that the fixed body and the rotational body installed on the leg of the chair come in contact with the floor horizontally to be stably anchored on the floor when a user sits on the chair. Therefore, the legs of the chair are fixed on the floor such that they are not pushed by external force. In addition, when the user stands up from the chair and needs to move the chair, the fixed body installed on the lower part of the leg for the chair is turned in one direction against the rotational body and then raised from the floor. Therefore, the chair can be moved to a desired place by using a driving ball in the rotational body.

    본 발명은 의자의 다수개로 기립설치된 다리의 하부에 고정설치된 고정본체와, 이 고정본체에 힌지로 결합되어 회동되고 구동볼을 갖는 회동본체와, 고정본체와 회동본체의 사이에 스프링을 설치하여서, 의자에 사용자가 착석했을때 의자의 다리에 설치된 고정본체와 회동본체가 바닥면에 수평으로 맞닿아 바닥면에 안정적으로 고정되어서 의자의 다리가 바닥면에서 외부에 힘에 의해 밀리지 않도록 고정되게 하고, 사용자가 의자에서 기립하여 의자를 이동이 필요시 의자의 다리 하부에 설치된 고정본체에서 회동본체를 의지하여 일방향으로 회동하여 고정본체가 바닥면에서 상승하게 되면 회동본체에 구비된 구동볼로 원하는 장소로 용이하게 이동하도록 한 의자용 회동쿠션바퀴장치에 관한 것이다.
