The rear cover of a vehicle-use AC generator is integrally formed with a portion that is shaped to enclose at least a part of a circumferentially extending region around the slip rings of the generator. Hence the rear cover, alone or in combination with an appropriately shaped brush holder, serves to seal the region of contact between the slip rings and brushes against intrusion of foreign matter, without the use of sealing members for preventing such intrusion.
