とする油圧緩衝器。A main piston connected to a piston rod is slidably inserted into a hydraulic oil chamber in the cylinder, and an orifice chair and a valve for opening and closing this orifice are provided on this main piston, and a valve that opens and closes this orifice is installed in the hydraulic oil chamber so that it can freely reciprocate. In a hydraulic shock absorber having a continuous gas chamber divided by a free piston, a permanent magnet is provided on the outer circumference of the free piston, and the outer circumferential surface of the free piston and the inner circumferential surface of the cylinder in which the free piston is guided. A hydraulic shock absorber characterized by interposing a magnetic fluid to seal these gaps between the two.
