ABSTRACT:
A cushion unit includes a shock absorber and a suspension spring. The shock absorber includes an open/close valve and a check valve which are arranged in parallel with each other. To increase the height of a vehicle body, the open/close valve is closed so that a piston pressure chamber is allowed to communicate with a spring bracket pressure chamber via the check valve. This causes a hydraulic fluid in the piston pressure chamber to be supplied into the spring bracket pressure chamber under pressure. Accordingly, a cylinder spring bracket slidably arranged around a cylinder of the shock absorber moves upward due to the pressure increase in the spring bracket pressure chamber. Since a lower end of the suspension spring is held against the cylinder spring bracket, the upward movement of the cylinder spring bracket compresses the suspension spring to increase a reactive force thereof so that the height of the vehicle body is increased due to the increased reactive force of the suspension spring.
