PROBLEM TO BE SOLVED: To shorten a length of a shaft by fitting a part of a choke coil into a recessed section of a support member. SOLUTION: In a fuel pump, a bearing holder 70 supports a bearing supporting a rotary shaft of an armature of the fuel pump. The recessed section 76 is formed on a side axially opposite to the surface facing to a commutator of the bearing holder 70. A choke coil 110 is formed to wind a coil body 114 on a choke core 112, and the choke core 112 is fitted into the recessed section 76 and comes into the inside of the bearing holder 70. The choke coil 110 can reduce electric noises generated when a brush slides on the commutators in sequence. COPYRIGHT: (C)2008,JPO&INPIT
