PURPOSE:To suppress the air pollution due to evaporated fuel by providing a closing control valve closing a valve closing a valve port when a cap is tightened to a fuel injection port in a fuel injection pipe. CONSTITUTION:When a cap 3 is loosened and lifted from feeding fuel, a closing control valve 12 is lifted, and an annular lower-end section 12b opens a valve port 11. As a result, the evaporated fuel in a fuel tank 1 flows into an annular passage 7 through a communicating pipe and is fed into a canister through the valve port 11, a valve chamber 6, and an evaporated fuel outflow port 14. The cap 3 is further loosened and removed from a fuel injection port 4. In this case, the evaporated fuel in a fuel tank has been fed into the canister, and only an extremely slight quantity of the evaporated fuel in an injection pipe 2 leaks into the outside air through the injection port 4, thus the air pollution can be suppressed. |
