バのバルブ構造。[Scope of Claim for Utility Model Registration] An orifice hole formed by communicating a liquid chamber partitioned in a shock absorber, and abutment on a first sheet surface and a second sheet surface, respectively, in order to open and close the orifice hole. A first-stage disc valve and a second-stage disc valve having a larger diameter are arranged in series in a state of a back-up member that regulates the above-mentioned deflection; a flow section that is provided between the back-up member and the second seat surface and allows the flow of hydraulic fluid between the two seat surfaces; and the second seat surface and the second stage disk. A valve structure for a shock absorber characterized by comprising: a constant area orifice formed by communicating the inside and outside of a contact surface with the valve;
