１記載の液圧緩衝器。[Scope of Claim for Utility Model Registration] A cylinder tube in which a liquid chamber and a reservoir chamber filled with hydraulic fluid in a liquid-tight manner are formed in the inside and the outer periphery, respectively, and the liquid chamber of the cylinder tube is divided and slides. a piston body connected to one end of the piston rod, an extension-side orifice hole formed in the piston body so as to communicate the partitioned liquid chambers, and an extension-side orifice hole to open during the extension stroke. An extension side valve disk provided on the piston body; A base body provided at the bottom of the cylinder tube that partitions the liquid chamber and the reservoir chamber; The liquid chamber and the reservoir chamber are communicated with the base body. a compression side orifice hole which is opened during a compression stroke; a compression side valve disk provided in the base body to open the compression side orifice hole during a compression stroke; a valve spring supported so as to be slidable in the axial direction of the body; a valve spring that urges the pressure side valve disk in the closing direction and whose end portion on the piston body side is supported so as to be slidable in the axial direction of the base body; both valves. A hydraulic shock absorber characterized by comprising: a position detection spring provided in series between the springs and urging both valve springs in the valve closing direction when the piston rod enters beyond a predetermined value. (2) The base body is formed of a base body main body fixed to the cylinder tube, and a sub-base body floatingly supported on the piston body side of the base body main body so as to be movable in the axial direction, and the pressure side 2. The valve disk according to claim 1, wherein the outer circumferential portion of the valve disk is circumferentially supported by the base body so that the inner circumferential side is deflected by hydraulic pressure, and is biased in the valve closing direction by the valve spring via the sub-base body. Hydraulic buffer.
