A first-stage disc valve and a second-stage disc valve are arranged in series in contact with the seat surface and the second-stage disc valve, respectively, and a predetermined amount of the first-stage disc valve is interposed between the two disc valves. Provided at a distance from the first stage disc valve to allow for deflection, and
a disc plate having a predetermined elasticity; a flow section provided between the disc plate and a second seat surface to allow flow of hydraulic fluid between the first seat surface and the second seat surface; and the second seat surface. A shock absorber valve structure comprising: a constant area orifice formed by communicating the inside and outside of a contact surface with a second-stage disc valve;
