Abstract

An automobile hydraulic shock absorber includes a cylinder body, a piston, an upper support, a piston rod, a volume adjustment mechanism, first and second communicating passages, and a pressure-applying mechanism. The piston rod is attached to the upper support via a rubber cushion. The volume adjustment mechanism includes a free piston. The first and second communicating passages communicate the first oil chamber and second oil chamber with each other in the cylinder body via a diaphragm. The pressure-applying mechanism is disposed outside the cylinder body, movement thereof is restricted by the upper support, and the pressure-applying mechanism pushes the piston rod downward.
