Before inner components of a hydraulic shock absorber, such as a cylinder, a piston and a piton rod, are placed, an outer shell is joined with a joint portion of an assembling apparatus so that a gas pressure chamber and the outer shell are in communication with each other. A low-pressure gas is supplied in the gas pressure chamber and the outer shell. Under a pressure of the low-pressure chamber, an oil tank subassembly is inserted in the outer shell and is fitted therein to form an oil tank. The oil tank is divided into an oil chamber and a gas chamber by a diaphragm. By this assembling method, it is possible to supply the low-pressure gas into the gas chamber without a need for a gas-supplying hole for supplying the gas into the gas chamber.
