Abstract
A fuel pump includes rotors that rotate, a pump housing that defines a rotor housing chamber that rotatably houses the rotors, and an outer circumferential side housing that includes a cylindrical portion formed in a cylindrical shape that surrounds the pump housing from an outer circumferential side and a narrowing potion having that narrows down with respect to the cylindrical portion. The fuel pump sucks fuel into the rotor housing chamber and then discharges the fuel due to the rotor rotating. A pump cover of the pump housing includes an inlet port that sucks fuel into the rotor housing chamber, and a sliding surface portion on which the rotors slide. An outer circumferential portion of the pump cover includes a joining portion joined to the narrowing portion, and a recessed portion that is recessed adjacent to the joining portion, the recessed portion allowing the outer circumferential portion to elastically deform.
