造。[Claims for Utility Model Registration] (1) Damping of a shock absorber having a control valve configured to adjust the damping force generated when the piston inside the cylinder slides by external operation. In the force adjustment structure, check valves are installed in the circuit that adjusts the rebound damping force and the circuit that adjusts the compression damping force, so that the damping force on the rebound and compression sides can be adjusted independently. A damping force adjustment structure for a shock absorber, characterized in that the damping force adjustment structure is formed. (2) The check valve is housed in an annular groove bored on the outer circumferential surface of the piston rod, and
A damping force adjustment structure for a shock absorber according to claim 1, wherein a holder is disposed on the outer periphery of the piston rod so as to cover the annular groove. (3) The shock absorber damping force adjustment structure according to claim 1, wherein the check valve is a plate valve curved in an arc shape. (4) A damping force adjustment structure for a shock absorber according to claim 1, wherein the control valve is disposed near the piston in the cylinder.
