Claims

[Scope of utility model registration request]

An armature housing made of resin and having an inverted bottomed cylindrical shape that houses motor components consisting of an armature, a commutator, a permanent magnet, and a cylindrical stator made of a yoke;
A resin holding a pair of brushes and their external connection terminals, which are disposed within the armature housing and fit into the lower end of the cylindrical stator so as to correspond to the commutator, and which are pressed into contact with the outer peripheral surface of the commutator. The brush plate is arranged so as to be fitted on the lower open end side of the armature housing so as to face the lower side of the brush plate at a predetermined interval, and is assembled and fixed to the lower open end of the armature housing. a resin partition plate forming a pump chamber between the pump chamber housing and the pump chamber housing, and a stud portion on at least one of the brush plate and the partition plate for positioning and maintaining the axial distance between the two plates. What is claimed is: 1. A motor-type fuel pump, characterized in that an engaging portion for restricting movement of the brush plate in the surface direction is provided at the protruding end that engages with the other side of the stud portion.
