<p>The apparatus has a tilt sensor (3) to detect a tilt state of a fuel tank (1). Airbags (5) vary a storage capacity of the tank by expansion and contraction operations. An air pump generates air pressure for providing to the airbags. A valve unit provides the pressure from the pump to the airbags or discharges the pressure to an atmosphere. A controller controls the unit and the pump based on a signal of the sensor.</p> |
