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 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.
