20110229355 | FUEL PUMP - A fuel pump has collar members, which are inserted in end portions of brush insertion holes of an end cover on an opposite side from brushes. The fuel pump has brush terminals press-fitted into the collar members. The brush terminals are connected to annular terminals, which are inserted in a secondary mold member by molding. Tip end portions of the collar members are press-fitted into the secondary mold member. Because of the press-fitting, an insulative resin intervenes between the brush terminals or between the annular terminals, to which different voltages are applied. Accordingly, passage of a leak current through fuel can be prevented, and electric corrosion can be prevented. | 09-22-2011 |
