Claims

[Scope of utility model registration request]

An outer container for storing fuel, a partition wall arranged to divide the outer container into a plurality of small chambers, a valve mechanism arranged in each of the partition walls, and a valve mechanism arranged on the bottom surface of one of the small chambers. The valve mechanism is configured to open only when tilted in one direction to allow fuel to pass between adjacent chambers in only one direction, and utilizes vibrations of the outer container. The fuel tank is characterized in that the fuel is gradually concentrated in the small chamber in which the supply pipe is disposed.
