<P>PROBLEM TO BE SOLVED: To provide an electric blower of small size and high output which comprises a magnetic field assembly that can assure heat resistance of a noise-prevention capacitor and sure operation of a temperature protector with no rising of a cost. <P>SOLUTION: A magnetic field assembly 15 is a spool comprising the magnetic field assembly 15 and a fan-like seal plate part 21a that covers a void formed at the inner peripheral part of a cylindrical bracket B in which the magnetic field assembly is built. The seal plate part 21a comprises, at a fan-like central part, a grid-like ventilation hole 21b, and a noise-prevention capacitor 23 and a temperature protector 24 are fixed at the positions corresponding to the ventilation hole. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
