And a stabilizer that prevents rolling of the vehicle. A satisfactory anti-dive effect could not be obtained. The chamber between the cylinders 3 is secured by the separator 4 to the upper chamber 5; And the lower chamber (6), the piston rod (7) is installed in the cylinder (3) so as to be movable up and down, the expansion valve having a distribution hole (8a) in the front end of the piston rod (7) 8) is integrally mounted, while the lower part of the cylinder 3 is installed in communication with the outer cylinder 2 via a compression valve 9 having a distribution hole 9a. When the furnace is opened, the compressed air of the air tank (11) flows into the outer cylinder of the shock absorber (1) through the control valve (10) and pushes the separator plate (4) to the air pressure so that the piston rod (7) of the shock absorber (1) At the same time to prevent the downward movement of the () and to raise the compressed piston rod (7) to prevent the front portion of the vehicle body to be forward.
