1. A fuel tank opening and closing device for opening and closing a fuel path for supplying fuel discharged from a fueling nozzle to a fuel tank, the device comprising:
- a tank opening forming member that forms the fuel path;
an injection port forming member that has (i) an injection port that constitutes a part of the fuel path, the injection port is adapted to be opened by the fueling nozzle, and (ii) a tank side path that is in a downstream side of the injection port and constitutes a part of the fuel path;
an insertion path forming member that has an insertion path that is in an upstream side of the injection port and constitutes a part of the fuel path, wherein the insertion path forming member guides a fueling nozzle inserted through the insertion path to the injection port;
a drainage mechanism that has (i) a drainage path that constantly connects the insertion path at the upstream side of the closed injection port with the atmosphere, the drainage path extends from the insertion path at the upstream side of the closed injection port through the insertion path forming member to the atmosphere, and the drainage path exhausts fuel accumulated inside the insertion path to the atmosphere, and (ii) a barrier member arranged in the drainage path; and
an injection port opening and closing mechanism for opening and closing the injection port,wherein the barrier member is arranged in the drainage path so as to guide the fuel accumulated in the insertion path to the atmosphere, the barrier member being configured such that the insertion path is inside the fuel tank opening and closing device and the insertion path is not visible from the outside of the fuel tank opening and closing device, and a ventilation resistance from the atmosphere to the insertion path is greater than the ventilation resistance from the insertion path to the atmosphere.

Abstract
A fuel tank opening and closing device is equipped with a tank opening forming member equipped with an injection port forming member having an insertion path and a tank side path arranged outside and inside an injection port, an injection port opening and closing mechanism for opening and closing the injection port, an insertion path forming member, and a drainage mechanism having a drainage path that connects the insertion path and the outside, and exhausts to the outside fuel that has accumulated inside the insertion path, and barrier members arranged on the drainage path. The barrier members are arranged with a labyrinth as the drainage path so that the insertion path cannot be seen from outside.
