A performance wagon castor according to an embodiment of the present invention comprises: an upper plate, which is fixed to the bottom surface of a wagon; and a lower plate, which has one or more wheels provided on the lower portion thereof, and which is coupled to the upper plate to be able to rotate relative thereto, wherein a bearing fixing shaft is provided on the upper surface of the lower plate, a housing is provided on the lower surface of the upper plate so as to surround the bearing fixing shaft, and the upper plate and the lower plate are coupled via a bearing interposed between the bearing fixing shaft and the housing. According to the present invention, by providing a spring ball member, it is possible to supplement the horizontal restoring force, which has been degraded by bearing coupling between the upper plate and the lower plate. Therefore, it is possible to provide a performance wagon castor, which can freely move in any direction, and which can stably move loaded articles, etc. while always remaining forced against the floor regardless of corrugations etc. of the floor.

    Un mode de réalisation de la présente invention concerne une roulette de wagon performante comprenant : une plaque supérieure, qui est fixée à la surface inférieure d'un wagon ; et une plaque inférieure, qui comprend une ou plusieurs roues disposées sur sa partie inférieure, et qui est accouplée à la plaque supérieure de manière à pouvoir tourner par rapport à cette dernière, un arbre de fixation de palier étant disposé sur la surface supérieure de la plaque inférieure, un logement étant disposé sur la surface inférieure de la plaque supérieure de manière à entourer l'arbre de fixation de palier, et la plaque supérieure et la plaque inférieure étant accouplées par l'intermédiaire d'un palier placé entre l'arbre de fixation de palier et le logement. Selon la présente invention, par la fourniture d'un élément bille à ressort, il est possible d'augmenter la force de rappel horizontale qui a été dégradée par accouplement de palier entre la plaque supérieure et la plaque inférieure. Il est par conséquent possible de fournir une roulette de wagon performante qui peut se déplacer librement dans une quelconque direction et qui peut déplacer de manière stable des articles chargés etc. tout en restant toujours pressée contre le sol indépendamment d'ondulations etc. du sol.

    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.
