A hydraulic damper with a rod guide made by pressing a circular plate is disclosed. This rod guide includes an inner tubular portion defining a bore supporting a piston rod, an outer tubular portion extending in the same direction as the inner tubular portion does, and a flange portion extending radially outwardly from the outer tubular portion. A ring is connected between an inwardly turned axial end portion of an outer tube and the flange portion. An annular sealing element retainer is disposed in the ring. The ring provides a transmission path of a force, thus preventing the sealing element retainer from being subject to the force.

Hydraulic damper

A spring seat is disposed about a tube which forms part of a shock absorber and supported in a predetermined position thereabout. The tube is subject to press bulge formation so that a portion of the tube becomes force fitted against a portion of the spring seat. Dies can be used to induce the formation of one or more projections which prevent the spring seat from moving axially along the tube. The force fit prevents relative rotation.
