The medium is used to filter the wear powder contained in the fuel when the motor portion is driven in the fuel. In the above fuel supply device, when the power is turned on, the rotor of the horsesports rotates, and the pump mechanism is actuated to burn the fuel in the fuel tank: the fuel pump portion is sucked into the fuel. The shell of the filter, in the middle. In this casing, the fuel passes through the filter medium to remove contaminants containing the abrasive powder generated by the brush or commutator (c__tator) of the motor portion. Thereafter, the fuel passes through the fuel filter and is then transmitted under pressure: the discharge port is sent to the nozzle of the internal combustion engine of the automobile via a conduit (for example, JP-A-8-284769). <In the structure of the conventional fuel supply device, the fuel discharged from the fuel pump portion will pass through the fuel filter and the portion, so that there will be a debris in the fuel, for example, by From turning into a motor. The P-knife brush or commutator produces 316933 5 4255312. The raw wear powder is discharged from the motor section, and then flows back to the motor section, and the slab is attached to the drive section of the motor section, thus reducing the function of the supply unit. SUMMARY OF THE INVENTION The present invention has been successfully solved by the above problems, and an object of the present invention is to provide a fuel supply device having high reliability, in which dirt generated in a motor portion does not adhere to a driving portion of a motor portion. The fuel supply device package provided by the present invention includes: a holding Wbracket placed along the opening portion of the fuel tank and provided with a discharge pipe, and a fuel pump for discharging fuel from the sample through the pipe: the fuel (4) :: :: The fuel pump includes a fruit portion for the fuel tank: into and out of the fuel' for rotating the rotor housed in the pump portion and allowing the fuel discharged from the pump portion to pass through the interior.
