Abstract
Abstract A caster is provided with a lock clip, which, when operable, joins the caster and a caster holder to prevent oscillatory movement therebetween. A first axle joins the caster body and the caster holder, the axle including a base frame at the bottom thereof which is receivable within the caster body. A rubber damper between the caster body and the base frame provides a shock absorbing effect between these two elements.
