Abstract: In a vehicle height adjustment device, an operation amount of an actuator increases in accordance with supplied current, a detector detects a vehicle height, and a changer changes the vehicle height in accordance with the operation amount of the actuator. The changer shifts to a vehicle height increasing state or to a vehicle height decreasing state based on whether the operation amount is not higher than a predetermined amount. A controller controls the current supplied to the actuator to make the relative position have a target value. The controller determines a target current supplied to the actuator based on a control map that correlates a deviation between the target value of the relative position and a detection value to the target current.
