Abstract
A resiliently mounted dual wheel caster is provided which includes an outer body including a hub with a transverse aperture, and an inner body member pivotally mounted to the outer body and mountable to an article to be supported by the caster. A resilient shock absorbing member is disposed between the inner body and the hub of the outer body. An axle is disposed through the aperture in the hub and resilient wheels are mounted one each end of the axle. The resilient wheels and the resilient member act in series to effectively absorb shock encountered by irregularities in travelled terrain and prevent such shock from reaching the supported article.
