項記載の油圧緩衝器の減衰力調整構造。[Claims for Utility Model Registration] (1) Generated when the piston inside the cylinder slides into the side passage that allows communication between the upper and lower chambers in the cylinder defined by the piston. In the damping force adjustment structure of a hydraulic shock absorber formed to have a rotary rotary valve that adjusts the damping force, the side passage has a check valve that operates only when sliding on the rebound side and only when sliding on the compression side. A damping force adjustment structure for a hydraulic shock absorber, which is formed so that either the upper chamber side opening or the lower chamber side opening is closed when the piston portion in the cylinder is at its maximum extension or maximum compression. . (2) A utility model registration request in which the upper chamber-side opening or lower chamber-side opening of the side channel is closed by a sleeve body slidably inserted into a piston rod that connects a piston part. range 1
The damping force adjustment structure of the hydraulic shock absorber described in . (3) Scope of utility model registration claim 1, in which the rotary valve is disposed near the piston in the cylinder
The damping force adjustment structure of the hydraulic shock absorber described in .
