The present invention relates to a caster. In particular, the caster is configured to be able to more smoothly rotate when moving 180 degrees, and makes it possible to smoothly rotate only the wheel without shaking a product disposed thereon. In order to achieve the above objective, a central body and a lower body are provided below a support plate formed at the upper end of the caster, the central body being configured such that two different column parts having central axes lying on a diagonal line are formed on the upper and lower sides of the central body, and wide areas are formed on both sides of the column parts to allow the mounting of two thrust ball bearings. Two thrust ball bearings are mounted between the support plate and the central body, and two thrust ball bearings are mounted between the central body and the lower body.

    La présente invention concerne une roulette. En particulier, la roulette est conçue pour pouvoir tourner davantage sans à-coups lors du déplacement de 180 degrés, et permet de faire tourner sans à-coups uniquement la roue sans secouer un produit disposé sur cette dernière. Afin d'atteindre l'objectif ci-dessus, un corps central et un corps inférieur sont disposés au-dessous d'une plaque de support formée au niveau de l'extrémité supérieure de la roulette, le corps central étant conçu de telle sorte que deux parties de colonne différentes présentant des axes centraux se trouvant sur une ligne diagonale sont formées sur les côtés supérieur et inférieur du corps central, et des zones larges sont formées sur les deux côtés des parties de colonne pour permettre le montage de deux roulements à billes de poussée. Deux roulements à billes de poussée sont montés entre la plaque de support et le corps central, et deux roulements à billes de poussée sont montés entre le corps central et le corps inférieur.

    본 발명은 캐스터(caster)에 관한 것으로, 특히 캐스터가 180도 이동할 시에 보다 원활하게 회전할 수 있도록 하였으며 상부에 있는 제품은 전혀 흔들리지 않고 바퀴만 원활히 회전할 수 있도록 발명한 것이다. 상기와 같은 목적을 달성하기 위하여 캐스터의 상단부에 형성되어 있는 지지판의 하측에 중심체와 하체부로 구성되어 있는 것으로, 상기 중심체는 중심축이 대각선상에 있는 다른 두 개의 기둥부가 상, 하측으로 형성되도록 하고 기둥부의 양측에는 넓은 면적을 형성하여 두 개의 스러스트 볼베어링을 장착할 수 있도록 한 것이다. 상기 지지판과 중심체간에 두 개의 스러스트 볼베어링을 장착하고 중심체와 하체부간에 두 개의 스러스트 볼베어링일 장착되어 있는 것이다.
