られて上記シリンダ内を上下の液室に隔成しつつ
摺動するピストンを収納すると共に、上記上下の
液室間を置換流動する作動液の流路中に、該作動
液に流動抵抗を付与して減衰力を発生させる減衰
力発生手段と、上記発生減衰力を可変制御する減
衰力可変手段とを並列に配置し、少なくともピス
トンロツドの伸側移動時に、上記減衰力発生手段
と減衰力可変手段を通過する前の作動液に低流動
抵抗を付与する補助減衰力発生手段を設けたこと
を特徴とする減衰力可変型液圧緩衝器。 Inside the cylinder, a piston is housed, which is installed at the end of the piston rod and slides inside the cylinder, dividing the cylinder into upper and lower liquid chambers, and a flow path for hydraulic fluid that displaces and flows between the upper and lower liquid chambers. A damping force generating means for generating a damping force by imparting flow resistance to the hydraulic fluid and a damping force variable means for variably controlling the generated damping force are arranged in parallel, and at least when the piston rod moves toward the extension side, A variable damping force type hydraulic shock absorber characterized in that an auxiliary damping force generating means is provided for imparting low flow resistance to the hydraulic fluid before passing through the damping force generating means and the damping force variable means.
