Patent ID: 8235187

Claim:
A hydraulic shock absorber comprising: an axle side inner tube slidably inserted to a vehicle body side outer tube; a partition wall member provided in an inner periphery of said inner tube, and a working fluid chamber and an oil reservoir chamber respectively comparted in a lower side and an upper side of said partition wall member; a hollow piston rod attached to said outer tube side inserted into said working fluid chamber through said partition wall member, and a piston sliding within said working fluid chamber provided in a leading end portion of said piston rod; the working fluid chamber of said inner tube comparted into a piston rod side oil chamber and a piston side oil chamber by the piston, the two oil chambers capable of being communicated by a compression side flow path and an expansion side flow path provided in the piston, and a compression side damping valve and an expansion side damping valve being respectively provided in outlets of the two flow paths; a hollow portion of the piston rod provided with a bypass path communicating a piston rod side oil chamber with a piston side oil chamber, and said bypass path provided with a needle valve; and a cap sealed to an upper end opening portion of said outer tube provided with a first adjusting portion moving the needle valve and adjusting a damping force caused by a passage resistance of the bypass path, and a second adjusting portion adjusting a deflection deformation of a compression side damping valve by adjusting a set load of a spring energizing the compression side damping valve in a closing direction, wherein the first and second adjusting portions are arranged side by side in a plan view of said cap; and each of said first and second adjusting portions is arranged at a position which is deviated from a center of said cap, in the plan view of said cap.
