A piston rod is movably inserted into the cylinder via a piston, and the piston partitions two oil chambers inside the cylinder.The two oil chambers communicate through a port provided in the piston, and a bypass provided in the piston rod. A main valve and a sub-valve are provided at the piston port and the bypass outlet of the piston rod, respectively, so that they can be opened and closed, and the main valve is held by a nut screwed onto the piston rod. A hydraulic shock absorber in which a spherical plug member larger than the inner diameter of the bypass is press-fitted into the end of the bypass to seal the bypass, and a portion of the piston rod corresponding to the nut is expanded in diameter to prevent the nut from loosening.
