ABSTRACT:
An axial length of the fuel pump is reduced, and the fuel pump is miniaturized, without reducing pumping performance.A space G is formed between coils19and the shaft7at the upper side of the core11, and the lower portion of the commutator8is inserted into the space G. As a result, a length B of the commutator8and an upwardly projecting length C of the coils19can be caused to overlap. Alternatively, a space H is formed between coils19and the shaft7at the lower side of the core11, and upper portion of the bearing10is inserted into the space H. As a result, a length F of the lower bearing and a downwardly projecting length E of the coils19can be caused to overlap. This overlapping allows the distance between the bearings of the shaft to be reduced.
