A hydraulic vibration buffer for connection between two members with a case coupled with the first member, a piston rod with its top end coupled with a second member, a piston coupled with a base end of the piston rod and housed within the cylinder case so as to divide the cylinder case into first and second chambers, fluid source, a tank, and a control valve disposed in fluid paths connecting the cylinder case, the fluid source, and the tank with one another. The vibration buffer also includes returning-force application device constituted by a swingable link with its one and other ends coupled with the first member and the housing block through which the fluid paths extend, and a pair of springs disposed between a center portion of the swingable link and the spool of the control valve.
