Abstract
A caster with an elastic member that absorbs impact forces during use. The elastic member can be placed between first and second portions pivotable with respect to each other about a pin. The elastic member can absorb impact forces between the first and second portions when in use. The elastic member can further include grooves that allow portions of the elastic member adjacent the grooves to flow into the grooves during impact, further absorbing impact forces.
