Abstract:
PROBLEM TO BE SOLVED: To provide a fuel supply device in which a portion of a stator is coated with a coating member made of resin which has first and second end coating parts and a plurality of connecting parts for connecting the first and second end coating parts to each other and a cylindrical discharge pipe is protrudingly provided integrally in the first end coating part, which is configured so that when die-molding the coating member made of resin, formation of defective coating members due to striking force generated by welded resin acting on a winding part at an end part at the opposite side of a Wesco pump of a bobbin is prevented.SOLUTION: A plurality of protrusions 46 which extend in a shaft direction while protruding inward in a radial direction from an inner periphery of a passage chamber 45 at a position corresponding to a tooth part 15b are formed integrally in a first end coating part 42a. Ends 46a at a magnetic pole member 24 side of the protrusions 46 are arranged in an end at the opposite side of a Wesco pump 5 of a bobbin 17. A rotary shaft 25 is supported rotatably on the plurality of protrusions 46 through a bearing member 28, and passages 47, through which a fuel passage 32 is communicated into a discharge pipe 42aa, are formed between the plurality of protrusions 46 respectively.SELECTED DRAWING: Figure 1
