Patent ID: 8887696

Claim:
An evaporated fuel handling apparatus for a vehicle, comprising: a fuel tank to reserve fuel; a fuel cap attached to a fuel filler port of the fuel tank configured to open and close the fuel filler port by manipulation with a key inserted in a key cylinder; an evaporated fuel reservoir to reserve evaporated fuel with adsorbent adsorbing the evaporated fuel; a charge path facilitating communication between the fuel tank and the evaporated fuel reservoir; and a purge path facilitating communication between the evaporated fuel reservoir and an air intake system of an internal combustion engine, wherein the fuel cap comprises a communication chamber which facilitates communication between the charge path and an inside of the fuel tank, the communication chamber comprises an on-off valve configured to open when an internal pressure of the fuel tank becomes equal to a predetermined pressure, thus facilitating communication between the fuel tank and the evaporated fuel reservoir, and the on-off valve is set open by a linkage member linked to the manipulation of the key, and thus sends the evaporated fuel in the fuel tank to the evaporated fuel reservoir.
