A caster support structure is used in a movable table (10) having a foldable top plate (12) at its upper end and front and rear paired casters (16a, 16b) at its lower end. At least rear paired casters (16b) are vertically movably provided to the lower end, and are interconnected with the top plate by a link (58) and levers (32, 40, 46) so that they project downwardly and retract upwardly upon the location of the plate at its vertically folded position and horizontal position, respectively. At the retracted position, antiskid members (18) attached to the rear ends stand on a floor in place of the retracted casters. <IMAGE>
