変型液圧緩衝器。 A cylinder filled with hydraulic fluid, a piston rod extending sealingly through one end of the cylinder, and two chambers, an upper fluid chamber and a lower fluid chamber, provided at one end of the piston rod. a piston having a damping force generating means for permitting a limited displacement flow of hydraulic fluid between the two chambers; It has a plurality of side holes with different opening diameters that communicate with the lower liquid chamber, and a plurality of communication holes that are rotatably fitted into the hollow part of the piston rod and selectively communicate with any of the side holes in the peripheral wall. In the variable damping force hydraulic shock absorber equipped with an adjuster, a female threaded portion is formed in the internal axial direction of one end of the piston rod, and the piston is attached to the piston rod via a tightening member that is screwed into the female threaded portion. A variable damping force type hydraulic shock absorber characterized by being fixed to.
