衝器。 A piston rod is movably inserted into the cylinder via a piston, and the piston defines two oil chambers within the cylinder. For connecting an actuator along the axial direction to the outer end of the control rod in a hydraulic shock absorber in which a rotary valve is rotatably inserted into the oil passage and is adjusted from the outside via a control rod. The body of the rotary valve is provided with a positioning hole and an opening that sequentially opens into the lateral passage of the piston rod as the rotary valve rotates. A hydraulic shock absorber characterized by being bored so that the horizontal passages do not face each other during assembly.
