徴とするストローク感応型液圧緩衝器。 A piston that slides inside a cylinder filled with hydraulic fluid while dividing the interior into two fluid chambers, pressure side and expansion side channels formed in the piston and communicating the two fluid chambers, and upper and lower surfaces of the piston. an annular seat portion formed on at least one of the seat portions; and a liquid that is seated separately on the seat portion from each outlet side opening end of the pressure side and expansion side channels opened on the inner circumferential side of the seat portion. a valve plate that provides flow resistance to the hydraulic fluid flowing into the chamber; a spring seat that contacts at least the outer surface of the extension side valve plate and transmits the spring force of the valve spring to the extension side valve plate; and a relative of the piston. and a variable mechanism that varies the spring force of the valve spring in accordance with a change in position, and presses a portion of the extension side valve plate corresponding to an approximately inner circumferential position of the seat portion on one end surface of the spring seat. A stroke-sensitive hydraulic shock absorber characterized by having a protrusion.
