of the outer circumferential housing 94 in the third embodiment the inner circumferential housing 96 is press inserted into the inner circumferential periphery of the cylindrical outer circumferential housing 94 so that the recessions 98 99 are defined the outer circumferential periphery of the outer circumferential housing 94 need not define a recession therefore the outer circumferential periphery of the outer circumferential housing 94 can be readily plated uniformly for protecting the outer circumferential housing 94 from corrosion as shown in fig4 the end cover 46 has a bearing hole 112 that directly supports one axial end of the shaft 82 in a fuel pump 110 the bearing hole 112 partially communicates with a fuel passage through which fuel is introduced from the motor portion 13 toward the outlet port 204 the end cover 46 has an outer circumferential periphery 114 that makes contact with the inner circumferential periphery 72 a of the housing 72 the axial end of the housing 72 is crimped onto the end cover 46 so that the inner circumferential periphery 72 a of the housing 72 and the outer circumferential periphery 114 of the end cover 46 define a fuel seal therebetween fuel may leak from the side of the inner circumferential periphery of the stator core 30 to the side of the outer circumferential periphery of the stator core 30 the fuel seal restricts the fuel from further leaking to the outside of the fuel pump 110 thus pressure of fuel increased in the fuel pump can be maintained the stator core 30 has an axial end.
