PURPOSE:To prevent the evaporated fuel from flowing out into the outside air and prevent the air pollution by providing a seal member hermetically coupled with the outer peripheral surface of an oil feed nozzle inserted into a fuel injection pipe from a fuel injection port to cut off the interior of a fuel tank from the outside air. CONSTITUTION:The upper space in a fuel tank 1 is filled with the evaporated fuel, and when a cap is removed, part of the evaporated fuel in the fuel tank 1 flows out into the outside air through a fuel injection port 4. Next, when an oil feed nozzle 12 is inserted into a nozzle insertion passage 8, a seal member 11 is hermetically coupled with the outer peripheral surface of the oil feed nozzle 12, thereby the interior of the fuel tank 1 is completely cut off from the outside air. Next, when fuel is fed through the fuel feed nozzle 12, fuel vapor is generated due to the bubbling of fuel, but the said vapor is fed to a canister 6 without flowing out to the outside. |
