ーバのバルブ構造。[Scope of Claim for Utility Model Registration] An orifice hole formed in a valve body that partitions a liquid chamber in a shock absorber so as to communicate the liquid chamber, and a first seat surface of the valve body for opening and closing the orifice hole. A first-stage disc valve is provided in contact with the valve and is bent to open an orifice hole during both low-speed and high-speed operation; a second-stage disc valve that is provided in contact with the second seat surface of the valve body so as to bend only when the valve body bends to open the orifice hole; A first disk, a plurality of disks provided overlapping the first disk, and a notch formed in the first disk to form a constant orifice between the second sheet surface and the plurality of disks. a notch, which is similarly formed in the plurality of disks and forms a constant orifice between the end surface of the disk on the side of the first disk and the end surface of the plurality of disks on the opposite side; A valve structure for a shock absorber, comprising: a communication means for communicating between a notch of a disc and a space between both disc valves.
