<p>A caster mounted on a cart, comprising a bracket (2) fixed to a vehicle body side, a link (3) connected rotatably to the bracket (2), a wheel (4) connected rotatably to the link (3), and a compression rubber block (20) compressively deformed according to the rotation of the link (3), wherein, because an initially compressed part (23) having a partially reduced cross-section is formed on the compression rubber block (20), the rotation of the link (3) is made smooth so as to suppress an input into the vehicle body. <IMAGE></p> |
