Title: FUEL FEEDING DEVICE
Abstract:
Provided is a fuel feeding device wherein the stator of a brushless motor comprises: a stator core formed by joining a plurality of magnetic steel plates stacked while burrs protrude in the same direction; a bobbin mounted to the stator core and comprising a pair of bobbin-constituting members consisting of a resin, the pair of bobbin-constituting members being capable of being divided in the direction of the axis of the stator core; coils wound on the stator core with the bobbin therebetween; and cover sections consisting of a resin, the cover sections being molded using, as insert parts, portions of the bobbin-constituting members and portions of the coils. Protrusions (47, 48) in contact with the stator core (15) are provided in a protruding manner on a surface of the specific bobbin-constituting member (38) of the pair of bobbin-constituting members (38, 39), the surface facing the stator core, the specific bobbin-constituting member (38) being disposed facing the protrusion direction (50) of at least the burrs (14a). As a result, the bobbin is not damaged by the burrs on the stator core side even if the brushless motor is reduced in size.
