PURPOSE:To reduce the number of components and improve assembly and decrease cost by providing a pressure room between an expanded diameter step section formed on the external surface of a cylinder and a spring catch. CONSTITUTION:When car height is increased, the pressure oil supplied from a sub-tank is introduced into a pressure room 28 through an oil path 29. Consequently, the pressure room 28 is expanded and a moving member 26 is moved right. A coil spring 27 is deflected and the car height is increased by the spring counrer-force. In adition, when the right end face of the moving section makes contact to a stopper ring 27 that prevents the slipping of the moving member 26, the maximum car height can be obtained. When the car height is decreased, the pressure oil of the pressure room 28 is discharged. The expanded diameter step section of a cylinder is used for a stopper. |
