減衰力調整構造。[Claims for Utility Model Registration] (1) A control valve is provided in a side passage in a piston rod formed to allow communication between an upper chamber and a lower chamber in the cylinder, and the piston body is fixed to the tip of the piston rod. In the shock absorber damping force adjustment structure, the damping force adjustment structure for a shock absorber includes a rebound damping valve provided in the set nut at the lower chamber side opening of the side passage, and the rebound damping valve includes an annular leaf valve. A shock absorber characterized in that an annular leaf valve is disposed on the upper surface of a valve case fixed inside the lower end of the set nut, and a valve disk is disposed on the upper surface of the annular leaf valve so as to be able to be seated and taken off. damping force adjustment structure. (2) A damping force adjustment structure for a shock absorber according to claim 1, wherein the annular leaf valve is formed so that its inner peripheral end is bent. (3) The damping force of the shock absorber according to claim 1, wherein the valve case has a valve seat portion on its upper surface, and the lower surface of the outer peripheral end of the annular leaf valve is adjacent to the upper surface of the valve seat portion. Adjustment structure. (4) A practical valve disk in which the valve disk is energized by a spring whose upper end is locked to a cap housed in a set nut, and whose lower end surface is in contact with the upper surface of the inner peripheral end of the annular leaf valve. A damping force adjustment structure for a shock absorber as claimed in claim 1.
