ABSTRACT:
A brush holding device for holding carbon brushes in sliding contact with slip rings of an alternator. The device has a brush holder formed by an insertion molding integrally with terminal plates. The brush holder has a pair of brush chambers for movably receiving the carbon brushes and a pair of pig tail chambers accommodating pig tails through which the carbon brushes are electrically connected to the terminal plates. The carbon brushes are resiliently biased into contact with the slip rings by means of coiled springs acting between the radially outer ends of the carbon brushes and the radially outer walls of the brush receiving chambers. The pig tails are extended into adjacent brush chambers through slits formed in the walls separating the pig tail chambers from associated brush chambers and are connected to the carbon brushes at lateral sides of the latter.
