In a caster which supports a wheel by using via a link 3 a bracket 2 to be fitted to a wheelchair or the like, an end of the link 3 is connected with a rotation axis of the bracket 2 via a rubber member 8 which is twisted and deformed resulting from oscillating motion of the link 3, and the link 3 and the bracket 2 are connected by a hydraulic damper 20 which damps the oscillating motion of the link 3, whereby an oscillation or a shock can be absorbed.
