The invention discloses a castor and a white board with a castor wheel, which are arranged in a teaching aid or furniture, such as a whiteboard, and conveniently and stably transform and transfer the stop and stop states. The casters of the invention comprises: to the nut is twisted to form a side of the lower end of the fixed shaft is combined with external thread wheel; that the wheels of the fixed shaft through a nut threaded through the shaft hole and the central node is, and the formation of running around the face of the shaft hole of the sliding part and the eccentric shaft side. The formation of running shaft hole clamped into the sliding parts, lifting device of eccentric rotating parts and have the other side shaft bolt bulges formed consisting of; that the sliding parts are clamped into the up and down movement in the vertical direction through the formation of the first central line of space and the wheels can rotate. The mobile and the second operation space and, in order to eccentric rotating parts are clamped and the eccentric shaft is introduced first and running space to the horizontal direction through the third operation and space form, twisted with internal thread formed on the upper part The subject was formed; running pole with the eccentric shaft bolt into the hole of the rotary member is perforated to the central shaft bolt and screw nut fixed; the eccentric rotating parts connected to running rod fixed; and the eccentric rotating member third in order to prevent the operation of the air trapped into the body. The detachment and stop rotation, fixing device composed of a first fixed part or second fixed part. The casters are assembled on a bracket fixed at the lower end of the column frame for placing the whiteboard.
