Abstract
A caster which is mounted in a trolley or the like having a bracket 2 connected to a body of a vehicle; a link 3 connected to rotate on the bracket 2; vehicle wheels 4 connected to rotate on the link 3; and a compressible rubber block 20 which deforms as the link 3 rotates. The compressible rubber block forms an initial compressible part 23 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 3.
