。 A brush that slides into contact with a slip ring fixed to the shaft of an electric motor, a bracket that engages the brush, a brush case that accommodates the bracket and the brush, and the brush that urges the brush against the slip ring. and the brush case, a detection pin installed upright on the bracket at the wear limit position of the brush, and a detection pin arranged at a predetermined distance from the slip ring to prevent the brush from being worn down to the wear limit. The present invention provides an electric motor brush wear detection device comprising a terminal that comes into contact with the detection pin and becomes electrically conductive when the detection pin is in contact with the detection pin.
