Partitioned chambers of an electric connector, which receive connection terminals electrically connected to windings of a stator, are communicated with an outside of the electric connector through primary communication holes. The primary communication holes are formed to direct at least one of perpendicular directions, each of which is perpendicular to a corresponding one of opening planes of outside openings of the primary communication holes, toward a downside when a central axis of a fuel pump is tilted relative to a vertical direction. In this way, a foreign object, which is accumulated in any of the portioned chambers, can be outputted to the outside through the primary communication hole even when the fuel pump is tilted in any direction. |

1. A fuel pump comprising:
a pump case that includes a suction port, through which fuel is drawn into an inside of the pump case, and a discharge port, through which the fuel is discharged to an outside of the pump case; a stator, around which a plurality of windings (161, 163) is wound, wherein the stator is configured into a tubular form and is received in the inside of the pump case; a rotor that is rotatably placed on a radially inner side of the stator; a shaft that is coaxial with the rotor and rotates integrally with the rotor; and an impeller that is provided to one end portion of the shaft, wherein when the impeller is rotated together with the shaft, the impeller pressurizes the fuel drawn through the suction port and discharges the pressurized fuel through the discharge port; and an electric connector that is provided to the pump case and includes:
a receiving chamber, which receives a plurality of connection terminals that receive an electric power to be supplied to the plurality of windings; anda plurality of primary communication holes, each of which communicates between an inside and an outside of the receiving chamber, wherein: the plurality of primary communication holes is formed to direct at least one of perpendicular directions, each of which is perpendicular to a corresponding one of opening planes of outside openings of the plurality of primary communication holes, toward a downside when a central axis of the pump case is tilted relative to a vertical direction. |
