<p>A method of arbitrarily changing damping characteristics of a double-tube shock absorber. A method of changing damping characteristics of a double-tube shock absorber (10) is characterized in that a screw hole (11a) is formed in an outer tube (11), oil is discharged from the inside of the shock absorber (10) via the screw hole (11a) and a replacement oil (35) is placed inside the shock absorber (10), a check valve (20) is fitted in the screw hole (11a), and gas is drawn from the inside of the shock absorber (10) via a flow path of the check valve (20), which is temporarily opened with the position of the check valve (20) of the shock absorber (10) set on the upper side, and nitrogen gas (36) for replacement is placed in the inside of the shock absorber (10).</p> |
