Abstract
A mud flap hanger for use on road vehicles such as trucks and truck-tractors wherein the hanger is adapted with pivotally mounted arms to which are attached mud flaps. The mud flaps may be moved from behind the wheel of a truck and stowed centrally between the rear wheels. Pivotal movement of the arms is achieved through use of a flexible bushing generally rectangular in shape wherein the inner walls of a generally square aperture has expansion slots and lubrication grooves for lubricating the arms carried within the aperture.
