Abstract
In a caster which supports a wheel by using via a link a bracket to be fitted to a wheelchair or the like, an end of the link is connected with a rotation axis of the bracket via a rubber member which is twisted and deformed resulting from oscillating motion of the link and the link and the bracket are connected by a hydraulic damper which damps the oscillating motion of the link whereby an oscillation or a shock can be absorbed.
