Claims

[Scope of utility model registration request]

At the bottom of the main tank, there is a first opening that opens upward.
a second sub-tank is fixed to the first sub-tank, and a second sub-tank is fixedly arranged to the first sub-tank.
The sub-tank is provided with a lower opening close to the bottom wall of the first sub-tank and a one-way valve on the upper wall, which opens only upward and outward due to internal pressure, and the four peripheral walls are closed. A fuel tank in which a suction pipe is opened in the first sub-tank.
