PURPOSE:To prevent the corrosion of a motor due to the leakage of a fuel and to prevent the leakage fuel from being ignited by a method wherein in the case of the roller vane pump, a rotor which is made of a magnetic material coated with a fluoric resin film and supported by a projection extending from a partition wall is driven by a magnetic member fixed to the shaft of the motor through the partition wall. CONSTITUTION:The disk-shaped magnetic member 1b is fitted on the top end of the output shaft 1a of the motor so as to extend normal to the output shaft and is magnetized to a single pole or a plurality of poles in the circumferential direction. Further, the magnetic member 1b made of a ferrite magnet or the like. The rotor 4 is made of an alnico east magnet coated with the fluoric resin film and is magnetized to a single pole or a plurality of poles in the circumferential direction. When the magnetic member 1b on the top end of the output shaft 1a of the motor is rotated with the rotation of the motor, the magnetic rotor 4 which is rotatably supported by the pump case projection 2a rotates due to its magnetic force in accordance with the transfer of the mgnetic force of the magnetic member 1b and as a result, the fuel is supplied from a fuel intake throughhole 6d to a fuel discharge throughhole 6f. |
