摘要： A piston (2) connected with a piston rod (3) is slidably fitted in a cylinder (1a) having a hydraulic fluid sealed therein. An extension-side main disk valve (21) generates a damping force in a high piston speed region against the flow of hydraulic fluid in an extension-side passage (8). A sub-passage bypasses (9) the extension-side main disk valve, and an extension-side sub disk valve (20) generates a damping force in an intermediate piston speed region. A compression-side main disk valve (19) generates a damping force in the high piston speed region against the flow of hydraulic fluid in a compression-side passage. A sub-passage (15) bypasses the compression-side main disk valve, and a compression-side sub disk valve (22) generates a damping force in the intermediate piston speed region. Damping force characteristics in the intermediate and high piston speed regions can be set according to the valve-opening characteristics of these disk valves. Therefore, it is possible to increase the degree of freedom for setting damping force characteristics.
