PURPOSE:To stabilize turning drive of a vehicle by providing a control plate with an oil hole facing a bottom valve communicating hole and making the opening area of a valve communicating hole variable in linkage with steering, in the hydraulic buffer of the vehicle with a bottom valve. CONSTITUTION:When a cylinder 2 makes a relative rotation with respect to a piston rod 10, the cylinder 2 rotates by accompanying the bottom valve 4. By this operation, the communicating hole 3a of the bottom valve 4 rotates in correspondence to the steering angle to decrease the opening area with respect to the oil groove 22a of the control plate 22. Accordingly, the flow resistance in the communicating hole 8a of a working oil between a reservoir chamber 3 and the interior of the cylinder 2 increases and the damping force is improved. Accordingly, the damping force of the buffer in the outside of the turning radius increases and inclination of the vehicle is suppressed to stabilize the turning drive. |
