ABSTRACT:
An electric fuel pump is provided with an insulative holding member 20 for holding choke coils 16 and connecting portions 23 between the choke coils and lead wires (14) as well as between the choke coils and brushes 10, to be mounted in the interior of a pump frame 1. In this electric fuel pump, the insulative holding member 20 holds and fixes the choke coils 16 and the connecting portions around the same, thereby to protect the choke coils 16 and the nearby connecting portions against vibration and shocks applied to the fuel pump. The holding member 20 also insulates conductive parts so that the same are not in contact with a housing 1 of magnetic material or the like, thereby to improve insulativity.
