Claim:
1. A vehicle height adjustment device comprising: a changer configured to change a relative position of a body of a vehicle relative to an axle of a wheel of the vehicle; and a controller configured to control the changer to make the relative position a target value so as to control a vehicle height of the body, the controller being configured to control the changer to maintain the relative position when there is a possibility of a malfunction in a current detector configured to detect a parameter for control, wherein the changer contains an actuator driven when supplied with a current and is capable of changing the relative position, the parameter is a value of the current supplied to the actuator, the controller contains a malfunction detector and a target current setter configured to set a target current supplied to the actuator in accordance with a target value of the relative position, and the malfunction detector determines that there is the possibility of the malfunction in the current detector when the target current is a current for increasing the relative position but the current detected is a current for maintaining the relative position, while the relative position keeps decreasing for a certain period of time.
