Summary:A wagon caster for a performance in accordance with an embodiment of the present invention, comprises: an upper plate fixed to the bottom surface of a wagon; and a lower plate which is equipped with at least one wheel on a lower part, and is coupled to the upper plate to be relatively rotated. In regards to this, a bearing fixing shaft is arranged on the upper surface of the lower plate, and a housing surrounding the bearing fixing shaft is arranged on the lower surface of the upper plate. Accordingly, the upper plate and the lower plate are combined by the medium of a bearing intervened between the bearing fixing shaft and the housing. According to the present invention, restoring force in a horizontal direction, which is declined by a combination of the upper plate and the lower plate, can be complemented by arranging a spring ball member. Thus, the present invention provides the wagon caster for a performance, which can freely be moved in every direction, and stably transports loaded goods while being in contact with a bottom surface all the time in spite of unevenness of the bottom surface. 본 발명의 한 실시예에 따른 공연용 왜건 캐스터는 왜건의 저면에 고정되는 상판, 하부에 하나 이상의 바퀴를 구비하고 상기 상판에 상대적으로 회전 가능하게 결합된 하판을 포함하며, 상기 하판의 상면에 베어링 고정축이 구비되고, 상기 상판의 하면에 상기 베어링 고정축을 둘러싸는 하우징이 구비되어, 상기 베어링 고정축과 상기 하우징 사이에 개재된 베어링을 매개로 상기 상판과 상기 하판이 결합된다. 본 발명에 의하면, 스프링 볼 부재를 구비함으로써 상판과 하판의 베어링 결합에 따라 저하된 수평방향의 복원력을 보완할 수 있다. 따라서, 전방향으로 자유롭게 움직일 수 있으면서 바닥면의 요철 등에도 바닥면에 항상 밀착된 상태로 적재된 물품 등을 안정적으로 이동시킬 수 있도록 하는 공연용 왜건 캐스터를 제공할 수 있다.
