Abstract
A caster includes a fixing portion installed on a bottom surface of an object, a wheel portion which is installed to be elevated into a flange portion and has a moving wheel provided on a bottom surface of the wheel portion, and an elevating portion to control the wheel portion to elevate into the flange portion. The wheel portion descends from the fixing portion to move the object and elevates into the fixing portion to fixedly dispose the object in a position. Therefore, a height of the caster is controlled to be high when the heavy object is being moved, and controlled to be low when fixing the object in a position, thus improving the appearance of the object.
