PURPOSE:To prevent the air pollution due to evaporated fuel by suppressing the evaporated fuel in a fuel tank from flowing out into the outside air when removing the cap of a fuel injection port. CONSTITUTION:While a fuel injection port 4 is closed with a cap 3, a contact plate 18 is in contact with the tongue section 12d of a closing control valve 12 to depress the closing control valve 12, thereby the annular, lower end 12b of the control valve 12 closes a valve port 11. When the cap 3 is loosened to feed the fuel, the cap 3 rises and the closing control valve 12 rises, thus the valve port 11 is opened. As a result, the evaporated fuel is fed into a canister through an evaporated fuel passage B, the valve port 11, a valve chamber 6, and an evaporated fuel outflow port 14. |
