The present invention provides a hydraulic shock absorber (10) comprising a piston rod side chamber (S1) for storing the piston rod (12) and a piston side chamber (S2) not storing the piston rod defined by the piston (35) in the damper cylinder (11B), a reservoir chamber (S3) defined in the piston side chamber via a partition wall member, and a pressure side valve (34,60) for generating the damping force at the time of compression provided each in the piston and the partition wall member, wherein a path (P2) for communication between the reservoir chamber (S3) and the piston rod side chamber (S1) is formed, a blow valve (80) to be opened at the time the differential pressure between the reservoir chamber (S3) and the piston rod side chamber (S1) reaches a predetermined value, for allowing the flow from the reservoir chamber (S3) to the piston rod side chamber (S1) is provided in the path (P2), and a blow valve adjusting device for operating the valve opening pressure of the blow valve (80) from outside is provided. <IMAGE> |
