FUEL SUPPLY DEVICE

摘要

A fuel supply device (20) has a chamber (21) disposed in a fuel tank (11). A fuel (12) in the chamber (21) is supplied to an internal combustion engine (15) via a fuel supply pipe (23). The fuel (12) which is returned from the internal combustion engine (15) into the fuel tank (11) passes through a return pipe (24) extending from the internal combustion engine (15) to the fuel tank (11). A tip portion (24a) of the return pipe (24) is positioned outside the chamber (21) in the fuel tank (11) so as to supply return fuel to a fuel introduction port (21a) formed on the chamber (21). A part of an upper edge (21b) of the chamber (21) is formed to be a step portion (21c) lower than the other part of the upper edge (21b) of the chamber (21), and the step portion (21c) is separated from the return pipe (24).
