Abstract
A fuel pump includes a housing including an internally-large cylindrical portion coaxial with an internally-small cylindrical portion. A press-inserted portion is press-inserted to the internally-small cylindrical portion. An accommodating cylindrical portion is located in the internally-large cylindrical portion. An accommodating disc portion is opposed to the impeller. A cover is in contact with the accommodating cylindrical portion on the opposite side of the accommodating disc portion. The accommodating disc portion has an impeller-side surface abutted to the accommodating cylindrical portion via an accommodating corner. The outer circumferential periphery of the press-inserted portion has an axial end defining a press-inserted corner on the side of the accommodating cylindrical portion. The accommodating corner is distant from the press-inserted corner for a first distance. The outer circumferential periphery of the press-inserted portion has an axially center portion being distant from the impeller-side surface for a second distance.
