ABSTRACT:
A fuel pump includes a pump portion for pumping fuel. The fuel pump further includes a magnet having magnetic poles circumferentially alternate with each other. The fuel pump further includes an armature on a radially inside of the magnet. The armature includes a rotor core provided with a coil formed of a wire. The armature is rotatable for driving the pump portion. A commutator, which is in a substantially disc shape, is provided to an axial end of the armature for rectifying electricity supplying to the coil. The rotor core has an axial end having an outer circumferential periphery defining a commutator-side collar portion extending toward the commutator. The coil is formed by winding the wire between an outer circumferential periphery of the commutator and the commutator-side collar portion.
