Abstract

PURPOSE:To prevent the vibration and sliding contact noise of a brush in a flat rotary electric machine by burying a part of the brush unit in an annular magnet formed with magnetic material mixed with resin material, thereby reducing the thickness of the rotary electric machine. CONSTITUTION:A mixture of resin material with magnetic material is annularly molded, and a magnet body is thus molded. The brush 122 is supported, for example on a resin brush base 121, and a brush unit 12 is thus formed. The base 121 as a part of the brush unit 12 is buried at a position corresponding, for instance, to the magnetic pole boundary of the magnet body 11, and the brush unit 12 is integrally fixed to the magnet body 11.
