PROBLEM TO BE SOLVED: To enable properly setting of a dead zone for a vehicle height value in flow rate characteristics of a vehicle height adjusting device.SOLUTION: A vehicle height adjusting device 40 includes an air supply on-off valve 60, a spool/sleeve mechanism containing a sleeve 44 and a spool 50, and an operation unit 70. A dead zone generating and energizing section 100 provided in the operation unit 70 includes a mounting part 102 having an energizing force receiver 104, and a pressing spring 106 having a pressing portion 108 at the top. The mounting part 102 integrated with the spool 50 transmits the energizing force of the pressing spring 106 to the spool 50. The pressing spring 106 presses the spool 50 against an on-off valve element 64 side of the air supply on-off valve 60 in a neutral state by energizing force balanced with the energizing force of a coil spring 66 which is a valve element energizing means. An eccentric pin 74 may be located at an arbitrary position in a guiding groove 78 in a neutral state using the pressing spring 106. |
