PROBLEM TO BE SOLVED: To provide a hydraulic shock absorber having simple construction for producing a sufficient shock absorbing effect when a piston rod is fully elongated and for allowing the use for a suspension device of a vehicle such as a truck or a bus to which a great load is applied. SOLUTION: The hydraulic shock absorber comprises a cylinder 2, a full elongation restricting member 7 provided on the cylinder 2, the piton rod 3 movably inserted into the cylinder 2 via a piston 4, and a stopper member 6 provided on the piston rod 3 for abutting on the full elongation restricting member 7 when the piston rod 3 is fully elongated. The full elongation restricting member 7 has an insertion recessed portion 8 into which all or part of the stopper member 6 is inserted while producing a hydraulic damping effect.
