Claims

[Scope of utility model registration request]

A cylinder filled with hydraulic fluid, a removable piston rod that extends sealingly through one end of the cylinder, and a piston that is fixed to one end of the piston rod and separates the inside of the cylinder into two fluid chambers. An assembly, a damping force generating means provided on the piston assembly, an adjuster for adjusting the damping force generated by the damping force generating means, and a check disposed in a hydraulic fluid flow path connected to the adjuster. 1. A hydraulic shock absorber comprising: a valve, wherein the check valve is opened when the piston rod is compressed, and the check valve is closed when the piston rod is expanded.
