Provided is a fuel pump of such a type that an alcohol-containing fuel flows through an electric motor (1), of which the life can be prevented from being shortened by suppressing a metal around a brush holder from being electrolytically corroded and extremely thinned by alcohol. A bracket (4) pivotally supporting an armature core (6) is divided into a first bracket (10) on which brush holder parts (10b) are formed and a second bracket (12) on which a terminal support part (12c) is formed. Partition surface parts (10h, 12f) fitted to each other in a stacked state are formed on both brackets (10, 12), respectively, to form a positive pole chamber (X) and a negative pole chamber (Y) by partitioning between the brush holder part for positive pole and the terminal support part and the brush holder part for negative pole and the terminal support part. |
