Abstract
A brush apparatus for a rotary electric machine has a brush with a pigtail, a brush holder and a spring. The brush holder is formed with a slit and a stopper piece. The pigtail is passed through the slit when the brush is inserted into the brush holder, and thereafter the stopper piece is bent to close an opening the slit. Thus, the brush apparatus simplifies an inserting operation of the brush to the brush holder and prevents the brush and the spring from coming off due to wear of the brush.
