Abstract
A caster which is mounted in a trolley or the like having a bracket connected to a body of a vehicle; a link connected to rotate on the bracket vehicle wheels connected to rotate on the link and a compressible rubber block which deforms as the link rotates. The compressible rubber block forms an initial compressible part which partially eliminates a surface area of the compressible rubber block. In this manner it is possible to restrain input forces on the vehicle body by smoothing out the rotation of the link
