Abstract: A primary metal terminal connects between a fuel pump and a drive circuit through a resin lid. A primary connecting point of the primary metal terminal connected to the drive circuit, is positioned around a drive control IC, and a primary exposed portion of the primary metal terminal, exposed to a receiving space of the resin lid is bent such that the primary exposed portion is resiliently deformable. A secondary metal terminal connects between an external circuit system and the drive circuit through the resin lid. A secondary connecting point of the secondary metal terminal connected to the drive circuit is positioned at a location that is further spaced from the drive control IC in comparison to the primary connecting point, and a secondary exposed portion of the secondary metal terminal exposed to the receiving space has a stiffness higher than a stiffness of the primary exposed portion.

Abstract: A circuit housing portion integrally molded above a lid main body portion has a bottom portion, which forms a vent space with the lid main body portion, and a vent hole, which extends through a portion between a protection space and an external space in the side portion. In a terminal, in which an intermediate portion is embedded in a bottom portion to extend between a fuel pump and a drive circuit through the bottom portion, an interface between the bottom portion and the intermediate portion is exposed to a protection space above the vent hole. A liquid-impermeable and gas-permeable membrane is mounted on an outer surface of the side portion to cover the vent hole to allow the fuel vapor to be discharged from the vent hole to the external space and to restrict liquid from entering the vent hole from the external space.

Abstract: A total dimension of spacing dimensions of a gap provided by a metal rod on a side opposite to a metal housing in a first assembling structure and a second assembling structure is set to be larger than a difference in a thermal expansion amount between a resin lid main body and the metal housing in a reference radial direction when a temperature exceeds a reference temperature. A total dimension of each of a spacing dimension of a gap provided by the metal rod on a side toward the metal housing and a spacing dimension between a resin protrusion and the metal housing in the first assembling structure and the second assembling structure is set to be larger than a difference in a thermal shrinkage amount between the resin lid main body and the metal housing in the reference radial direction when a temperature falls below the reference temperature.
