を特徴とする減衰力調整式アブソーバ。 A piston with a compression damping valve and a rebound damping valve arranged side by side in order to partition an upper chamber and a lower chamber is slidably provided in the cylinder, and rotates within a piston rod having a side hole, the piston having a diameter smaller than that of the side hole. In a shock absorber having a rotary valve equipped with an orifice, the orifice of the rotary valve is arranged in multiple stages vertically and in each stage in the circumferential direction, and the side hole of the piston rod is also vertically and circumferentially provided with the orifice. A check that is provided in large numbers in the same phase, covers all but a portion of the side holes of one stage of the piston rod, and covers the side holes of other stages, and allows oil to flow from the lower chamber to the upper chamber, but not vice versa. A damping force adjustable absorber characterized by a valve installed coaxially with the piston rod.
