Abstract
A fuel pump for supplying fuel drawn from a fuel tank into an internal combustion engine comprises a rotor, a rotation shaft, bearing members and a drawing force generative means. The rotation shaft revolves integrally with the rotor. The bearing members support both axial ends of the rotation shaft. The stator is disposed on an outer circumference of the rotor and surrounds the rotor. The drawing force generative means generates drawing force for drawing fuel from the fuel tank by means of rotation force of the rotor. The rotor has a recess in a center of its axial end portion. Moreover, at least one of the bearing members is disposed in the recess.
