Claims

[Scope of utility model registration request]

Upper and lower oil chambers are formed through a piston that is slidably housed in the cylinder, and an operating rod is rotatably inserted through the piston rod, and upper and lower oil chambers are formed through a regulating valve provided on the operating rod. While making the area of the communication passage variable, an air chamber is formed by covering the outside of the cylinder with a cover and an elastic tube, and the cover is connected to the protrusion of the piston rod, and the piston is adjusted according to the amount of air supplied to the air chamber. In a hydraulic shock absorber that allows the rod to be relatively displaced, a solenoid is attached to the tip of the piston rod, and the movable shaft of the solenoid is connected to the annular gap between the piston rod and the operating rod. form an air passage in the
A hydraulic shock absorber characterized in that the air passage is communicated with an air introduction passage passing through the movable shaft in the axial direction, and the air passage is communicated with the air chamber via a side passage provided in the piston rod.
