Abstract
An AC generator for a vehicle has a brush unit. The brush unit comprises a brush held in sliding contact with a slip ring, a spring for pressing the brush, a brush holder having a portion for receiving the brush, and a slip ring cover for covering the outer periphery of the slip ring formed on a rotary shaft. The slip ring cover includes a first wall portion and a second wall portion which are generally shaped like an arc, a cover portion for closing the end portion in the axial direction, and a side wall portion. The first wall portion and the second wall portion overlaps each other, and a suction/discharge port is formed between these wall portions.
