<p>A fuel supply device is provided with a bearing (20) which is secured to the center of a rotor (10) and a rotor holding member (12) which is inserted and fitted in the center of the bearing and which pivotably holds the rotor (10), and the rotor and the bearing are adapted to pivot together. As a result, the fuel supply device is configured in such a manner that the mass of the rotor is reduced, pump performance is not reduced, and the rotor has good ability of following magnetic poles formed in the circumferential direction of the stator core.</p> |
