PROBLEM TO BE SOLVED: To provide a motor-driven fuel pump having a structure advantageous in manufacturing and a pump body structure for the fuel pump for realizing a sliding bearing surface having high flatness and extremely little surface roughness while maintaining various advantages derived from the structure flat in the shaft direction. ;SOLUTION: This motor-driven fuel pump has a pump housing having an inlet and an outlet, a body structure inclusing a pump impeller rotatably arranged in the housing and a pump body structure driving electronic commutation switching control type DC motor having a stator and a rotor integrally formed in the impeller. A part of the stator is partially intruded in the pump housing.;COPYRIGHT: (C)2001,JPO
