Abstract

PURPOSE:To prevent the occurrence of a trouble caused by an intrusion of dust and the like into the subject generator by a method wherein the outer circumference of a collector ring is convered by the cylindrical part of a dustproof cylindrical member a contacting surface is formed on a brush retainer, and the brush retainer is elastically contacted to the circumferential section of the notched part provided on the dustproof cylindrical member. CONSTITUTION:The dustproof cylindrical member 13 is installed on the inner surface on the end face side of a rear bracket 4. This dustproof cylindrical member 13 consists of a cylindrical section 14 and a flange section 15, to be used for mounting, provided at one of the aperture sections, and they are formed in a body by performing a reducing process on a steel plate, for example. On this cylindrical section 14, a longitudinal notched section 16, to be used to insert a brush 11 in the prescribed point, is formed. Als9, an inserting hole 20 to insert a screw for fixing of the brush retainer 7 is provided at the prescribed part on the flange section. Besides, a flange section 8 is protrudedly provided at a point close to the cylindrical section 14 on both side-faces of the brush retainer 7, and a contacting surface opposing to the cylindrical part 14 on the flange section 8 is formed, thereby enabling to obtain an excellent dustproof effect.
