Claims

[Scope of utility model registration request]

An armature housing having a substantially inverted bottomed cylindrical shape in which motor components are housed, and a pump that is assembled and fixed to the open end of the armature housing through a partition plate, and an impeller is rotationally driven between the partition plate and the armature housing. a pump chamber housing that forms a chamber and has a suction port opened at the lower center thereof; and a cup-shaped cup that is fitted to the outside of the opening end of the armature housing so as to cover the suction port below the pump chamber housing. An air vent hole is formed in a side wall portion near the pump chamber on the open end side of the armature housing, and the filter member is provided with an air vent hole so as to face the open end of the air vent hole at a predetermined distance. A motor-type fuel pump characterized in that a side wall portion of the pump is extended.
