摘要：A fuel pump includes a pump part, a motor part, two brushes, two pigtails, andan urging member. Each pigtail is made of a linear conductive member and includes one

end portion electrically and mechanically connected to its corresponding brush. Theurging member includes one end engaged with a motor casing, and the other endpressing and urging each brush against a commutator from its other axial end face. Adistance between an inclined surface of the brush and a sliding surface of the

commutator in an axial direction of the brush becomes longer toward a rear side of thebrush in a rotation direction of the commutator. A side surface of each brush and an innerwall of the motor casing, which defines two brush accommodating chambers, define aclearance therebetween. Each pigtail includes an extension portion extending from itsone end portion toward the rear side in the rotation direction of the commutator.
