料ポンプ。 In a fuel pump with a built-in DC motor, a plurality of main segments are disposed on the cylindrical surface of the commutator support located at the end of the armature, and at least the surface of the commutator support has a surface that is more durable than the main segments. A flat sub-segment made of a material with excellent wear resistance is arranged, and on the casing side, a pair of main brushes press against the main segment in the radial direction, and a pair of sub-segments press against the sub-segment in the axial direction. A fuel pump characterized in that the fuel pump is provided with a brush, and when the current is small, the main brush is energized, and when the current is large, the auxiliary brush is energized.
