PROBLEM TO BE SOLVED: To allow exertion of prescribed functions while improving installation performance of a hydraulic shock absorber. SOLUTION: A spool 4 has, at its one end, another stopper part 44 that produces an effective stroke V2 of the spool 4 between a valve housing 5 and the stopper part, and has, at another end side, one stopper part 43 that produces an effective stroke V1 of the spool 4 between the valve housing 5 and the stopper part. On the other hand, another end part (82) of the spool is connected to a rod body 3 in a hydraulic shock absorber or to a fixed side B connected with the rod body 3 in the presence of an input means 8. The input means 8 allows another end part (82) of the spool 4 to be inside a tubular body 81 that is coaxially arranged with the spool 4 and is connected to the fixed side B, and another end part (82) is sandwiched between a pair of balance springs 83, 84 stored in the tubular body 81.
