PROBLEM TO BE SOLVED: To stop fuel supply and prevent fuel discharge when a fuel supply nozzle faces a direction other than the direction for the nozzle to be inserted in the fuelling port of a plastic container. SOLUTION: Fuel supply nozzles 22, 23 are provided with an air introduction line opening/closing mechanism 75 communicating with an air introduction line 72. The mechanism 75 is provided with a bent pipe line 76 curved in a U-shape, a spherically shaped valve sheet 77 formed in the receding part in the middle of the line 76, and a closing ball 78 which is a metallic ball and moves to a valve sheet 77 closing position when the nozzles 22, 23 are in a horizontal condition. When the nozzles 22, 23 face a direction other than the perpendicular direction, in a condition where they are not inserted in the fuelling port of a container 46, a fuel supply stop mechanism is activated and fuel supply is automatically stopped for preventing the discharge of fuel in its surrounding area because the line 72 is shut even when a fuel supply start switch 42 is operated and turned on.
