摘要： 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.

摘要： PURPOSE:To arrange so that a long life and a stable action may be assured by providing a flexible member between a part of the external ring of a bearing whose internal ring is fixed to a rotary shaft and a bracket and providing a buffer action between the bracket and the bearing as well as a rotation stopping action on the external ring. CONSTITUTION:An external ring 1 for a bearing 12 interposed between a bracket and a rotary shaft 5 prevents abrasion against an insert 14 of high hardness at time of rotary contact. In addition, an external ring 19 for the bearing 12 is opposed to the insert 14 and the external periphery of a part crowded out of the insert is attached with ''O'' ring 13. This ''O'' ring is made of comparatively harder synthetic rubber and is interposed between the external ring 19 and a bracket 17 to maintain an airtightness between the side of the insert 14 and a protrusion of a housing 1. Under this constitution, an abrasion on the insert 14 can be reduced and a stable rotary action over a long period be assured.
