シ。 A rotor having a field winding fixed to the shaft of the generator; a slip ring in electrical conduction with said field winding and fixed to said shaft; attached to a retainer which presses against said slip ring and wears to its effective length; An automotive alternator comprising a brush, an end bracket to which the retainer is fixed, which has a pin insertion hole for temporarily fixing the brush to the top of the slip ring with a pin when the generator is assembled, and the like. One or more holes of various shapes are provided in the brush longitudinal direction from the outer radius of the slip ring within the effective length of the brush, and the pin is inserted from the outer radius of the shaft based on the difference L between the outer radius of the slip ring and the outer radius of the shaft. Difference B in the L dimension from the distance to the hole and the hole length H from the outer radius of the slip ring
A brush for an automotive alternator, characterized in that the relationship L+B>H and H>B, and the difference l between the effective length of the brush and the hole length H is L>l.
