본 고안은 물건을 운반할 때 사용하는 카트를 주행시키기 위하여 카트의 저면에 설치되는 캐스터에 관한 것으로서, 좀 더 상세하게는 카트의 주행방향을 원활하게 전환할 수 있도록 구성된 캐스터를 제공하려는 것이다. The present invention relates to a caster which is installed on the bottom of the cart to drive a cart used when carrying an object, and more particularly, to provide a caster configured to smoothly switch the driving direction of the cart. 상기와 같이 하기 위한 본 고안은 카트에 설치하기 위한 베이스플레이트(1)와 그 하부에 휠의 주행방향을 전환할 수 있도록 하기 위한 회전브라켓(2)을 설치하며, 상기 회전브라켓(2)에는 휠을 설치하기 위한 포크프레임(3)을 설치하고 그 선단부에 휠축(4)으로 휠(5)을 설치하되, The present invention for doing as described above is installed on the base plate (1) for mounting on the cart and a rotating bracket (2) to be able to switch the driving direction of the wheel on the lower portion, the rotary bracket (2) Install the fork frame (3) for installing the wheel 5 to the wheel axle (4) to the front end, 상기 회전브라켓(2)의 중심과 포크프레임(3)의 선단부에 설치되는 휠(5)의 중심이 수직선상에 일치되게 설치하며, The center of the rotating bracket (2) and the center of the wheel (5) which is installed on the front end of the fork frame (3) is installed to match the vertical line, 상기 포크프레임(3)의 일측으로 추 무게의 중심이동에 의한 관성작용을 하도록 돌출부(6)를 일체로 형성하여 구성된 것이다. One side of the fork frame (3) is formed by integrally forming the projection (6) to inertial action by moving the center of gravity weight. 이상과 같은 본 고안의 캐스터는 휠이 회전브라켓의 수직 중심선상에 있기 때문에 방향전환시 편심하중에 영향을 받지 않으면서 포크프레임의 돌출부가 추 무게의 중심이동에 의한 관성작용을 하기 때문에 휠의 방향전환을 더욱 용이하게 할 수 있어 카트 사용자가 무리하게 힘을 사용하지 않고도 편리하게 방향전환을 할 수 있도록 하는 효과가 있으며,  Since the caster of the present invention has the wheel on the vertical centerline of the rotating bracket, the direction of the wheel is inertial due to the center movement of the weight of the fork frame without being influenced by the eccentric load during the change of direction. This makes it easier to switch, so that the cart user can easily change the direction without using excessive force. 또, 하중이 수직선상으로 작용하기 때문에 각 연결부분이 재쳐지지 않고 바른 연결상태를 유지할 수 있어 캐스터가 파손되는 것을 방지하여 오랜기간 사용할 수 있으므로 유지보수에 따른 경비를 절감할 수 있으므로 ...
