Abstract
A cylindrical shock absorber having a piston rod extending outwardly therefrom to which a disc-like upper cover plate is secured. The cover plate is castellated with peripheral teeth arcuately spaced from one another extending radially from the outer edges. The dust tube is formed from plastic sheet stock having a series of perforations adjacent one edge sized and spaced to receive the teeth of the cover plate. The sheets are wrapped onto the cover plate with the teeth projecting through the openings to form an outer cylinder. The adjacent end edges of the cylinder are heat welded or otherwise secured so that the cylinder is retained on the cover plate to form a cylindrical dust tube.
