A position-and-velocity dependent hydraulic damper (10) is provided. The hydraulic damper (10) has piston valve (22) fixed to a tip of a piston rod (11), a base valve (27), and a reservoir chamber (15). The base valve (27) has a compression side port (31). Between a first valve (24) and the base valve (27), a first spiral spring (28) is provided, and between the first valve (24) and the piston valve (22), a second spiral spring (23) is provided. The compression side port (31) is closed by the first valve (24) around the maximum compression state, reducing the flow rate of oil to the reservoir chamber (15). A second valve (33) passing through the centers of the first valve (24) and the base valve (27) adjusts the flow rate of the oil to the reservoir chamber (15) with a pressure equal to or higher than a prescribed level of an oil chamber (21b). |
