An inner space of a fuel tank 12 is divided into a fuel chamber 14 filled with CNG and an oil chamber 15 filled with oil using a movable piston 13 in a sealed state. During deceleration of the vehicle, an oil unit 24 is operated as a pump and oil is supplied to the oil chamber 15. In the above state, when the CNG within the fuel chamber 14 is compressed so as to accumulate energy in compression. The CNG within the fuel chamber 14 is expanded during high load operation or acceleration operation such that oil flows from the oil chamber 15.
