Claims

[Scope of utility model registration request]

A chamber installed at the bottom of a fuel tank of an automobile. When the liquid level of low fuel remaining in the fuel tank is inclined, the inclination causes the fuel to flow into the chamber and raise the liquid level in the chamber. In the apparatus for preventing the tip of a suction pipe opening into the chamber from being exposed above the liquid level, a side space chamber having a fuel intake port is formed on the outside of both left and right sides of the chamber, The left and right side space chambers are connected to the chamber chamber by pipes extending along the outside of the front and rear walls of the chamber, each pipe having one end connected to a corner of one side space chamber. The outermost curved part from the chamber is formed here, and the other end is connected to the corner of the chamber on the side of the other side space. When the liquid level is inclined, one pipe is located below the inclined liquid level in the side space chamber, and the outermost curved part of the other pipe is located below the inclined liquid level in the side space chamber. A chamber for a fuel tank for an automobile, characterized in that the chamber is positioned above a surface.
