Abstract
A hydraulic shock absorber for vehicles including inner and outer cylinders, and a casing defining an oil chamber therein. The oil chamber is arranged to be in communication with the interior of the inner cylinder. A gas chamber hermetically defined by an elastic metal membrane and having a predetermined volume of gases confined therein is disposed in the oil chamber. The arrangement provides desirable damping characteristics in a substantially low damping force range as well as in an inherent or preset damping force range.
