A position- and velocity-dependent hydraulic shock-absorbing device (10) is provided. The hydraulic shock-absorbing device (10) has a piston valve (22) secured to a distal end of a piston rod (11), a base valve (27), and a reservoir chamber (15). The base valve (27) has a compression-side port (31). A first helical spring (28) is provided between a first valve (24) and the base valve (27), and a second helical spring (23) is provided between the first valve (24) and the piston valve (22). The compression-side port (31) is closed by the first valve (24) near the time of greatest compression, and the flow rate of oil liquid to the reservoir chamber (15) therefore decreases. A second valve (33) passing through the middle of the first valve (24) and the base valve (27) uses a pressure equal to or greater than the prescribed pressure of an oil chamber (21b) to adjust the flow rate of oil liquid to the reservoir chamber (15). |
