A vehicle height adjustment device includes a rear suspension, an electromagnetic valve control unit, and a weight estimation unit. The rear suspension includes a support member. The electromagnetic valve control unit determines a target movement based on an interrelation between the target movement and a weight applied to a vehicle, under which the target movement is set to an upper limit when the weight is larger than a predetermined weight, so that an actual movement of the support member reaches the target movement. The electromagnetic valve control unit determines the target movement based on a temporary weight. The weight estimation unit increases the temporary weight, even when the actual movement reached the target movement. The electromagnetic valve control unit decreases the target length, even when the temporary weight increased. The weight estimation unit estimates as the weight the temporary weight when the actual length has finally reached the target length.
