Fuel cutoff valve

A fuel cutoff valve comprising:

• a main body portion having an upper wall, and a lid body portion;
• a valve mechanism accommodated in the main body portion, the valve mechanism having a float and a valve body that is disposed above the float, the valve body preventing a vapor from flowing in a vapor passage through which a fuel tank communicates with a canister by closing a connecting hole bored in the upper wall of the main body portion at a position above the valve mechanism;
• an upper space that is defined by the upper wall of the main body portion and the lid body portion;
• a tube body that has a tube passage to be communicated with the upper space and introduces a fuel gas to the canister, wherein the tube passage has a tube bottom wall;
• a retaining chamber that is defined in the upper space by a first fuel shielding plate having a front shielding piece that is disposed in front of the connecting hole between the tube body and the connecting hole and a second fuel shielding plate, wherein the second fuel shielding plate has a rear shielding piece that is disposed behind the connecting hole, so the connecting hole is disposed between the rear shielding piece and the tube body, to retain a liquid fuel stored in the upper space, and the retaining chamber has a bottom wall surface constituted by the upper wall of the main body portion;
• a liquid reservoir portion defined between the tube body and the front shielding piece and having a reservoir bottom wall located lower than the tube bottom wall to store a liquid fuel flowing out of the retaining chamber;
• and
• a communication portion which defines a liquid flow path extending from the bottom wall surface of the retaining chamber to the reservoir bottom wall of, the liquid reservoir portion and through which the retaining chamber communicates with the liquid reservoir portion,
• wherein every portion of the liquid flow path is located lower than the tube bottom wall and higher than the reservoir bottom wall, and
• wherein the communication portion is formed at a position deviated from the tube body so as not to overlap the tube body, when the tube body is seen in an axial direction of the tube body.
