A refueling portion structure of a fuel tank has: a refueling pipe that has a refueling port; an opening/closing valve that is provided on a flow path within the refueling pipe; an accommodating portion that is provided at an outer side of the refueling pipe, that accommodates at an interior thereof an adsorbing material that adsorbs vapor fuel that has formed due to the liquid fuel evaporating, that communicates with the flow path further toward the refueling port side than the opening/closing valve, and into which the liquid fuel can flow; an atmospheric air passage, by which the accommodating portion communicates with atmospheric air; and a vapor movement passage, by which the accommodating portion communicates with an engine, and that is for moving vapor that is within the accommodating portion to the engine due to negative pressure from the engine. |

1. A refueling portion structure of a fuel tank, comprising:
a refueling pipe that has a refueling port into which a refueling nozzle is to be inserted, that is connected to a fuel tank, and that sends liquid fuel, supplied from the refueling nozzle, to the fuel tank; an opening/closing valve that is provided on a flow path within the refueling pipe and closes the flow path, and that, when pushed by the refueling nozzle, opens the flow path; an accommodating portion that is provided at an outer side of the refueling pipe, that accommodates at an interior thereof an adsorbing material that adsorbs vapor fuel that has formed due to the liquid fuel evaporating, that communicates with the flow path further toward the refueling port side than the opening/closing valve, and into which the liquid fuel can flow; an atmospheric air passage, by which the accommodating portion communicates with atmospheric air; and a vapor movement passage, by which the accommodating portion communicates with an engine, and that is for moving vapor that is within the accommodating portion to the engine due to negative pressure from the engine. |
