Abstract
There is provided an over-fueling prevention valve including a housing provided with a first opening, a second opening, and a first valve seat; a main valve provided with a one end opening, the other end opening, and a second valve seat; a first biasing portion; a sub valve; and a second biasing portion. Biasing forces of the first biasing portion and the second spring are set such that a valve re-closing pressure of the main valve is higher than a valve re-opening pressure of the sub valve. In a state in which the main valve is separated from the first valve seat, the first opening and the second opening communicate with each other via an external space.
