PROBLEM TO BE SOLVED: To adjust a vehicle height of a vehicle by using one sensor.SOLUTION: A vehicle height adjusting device 20 comprises: a vehicle height adjusting suspension 21 which has a support member 141 for supporting one end of a suspension spring 110, and a jack chamber 142, and changes a vehicle height of a vehicle body by moving the support member 141 by the supply of liquid to the jack member 142; a hydraulic pump 210 which has a pump-side oil chamber Z1 connected to the jack chamber 142 via an oil passage 23, and variable in a capacity by the movement of a pump-side piston 213, and supplies the liquid to the jack chamber 142 from the pump-side oil chamber Z1; a pressure sensor 215 which detects pressure in the pump-side oil chamber Z1; a motor 221 which drives the pump-side piston 213; and a control device 50 which calculates a compression amount L2 of the suspension spring 110 on the basis of the pressure in the pump-side oil chamber Z1 detected by the pressure sensor 215, and calculates a moving amount L1 of the pump-side piston 213 by the motor 221 on the basis of the compression amount L2.SELECTED DRAWING: Figure 4 |
