ポンプ。 A casing, a pump part that pumps fuel from the suction port to the discharge port side of the casing, an electric motor provided in the casing to rotationally drive the pump part, and a plurality of commutator pieces are connected through a gap. In a fuel pump comprising commutators which are spaced apart in the circumferential direction and which drive the electric motor by energizing each commutator piece by slidingly contacting each commutator piece with a brush, the commutator main body constituting the commutator has each of the commutators. A fuel pump characterized in that a fuel circulation groove wider than the gap is formed along the gap between the child pieces.
