A brush holding device for holding brushes in sliding contact with slip rings of an alternator, comprising:

• a brush holder formed in one body from an electrically insulating material to include a pair of brush chambers open at one of their ends to face said slip rings;
• a pair of brushes movably received in said brush chambers respectively;
• coiled springs disposed in said chambers respectively for urging one end of said brushes into resilient sliding contact with said slip rings;
• a pair of terminal plates fixed to said brush holder;
• and
• pig tails electrically connecting said brushes and said terminal plates respectively,
• said brush holder having a pair of pig tail chambers respectively adjacent said brush chambers and further having a pair of walls separating said pig tail chambers from said brush chambers respectively,
• said terminal plates being in said pig tail chambers respectively,
• there being a slit in each of said separating walls adjacent the other end of the respective brush,
• said pig tails being accomodated by said pig tail chambers and extending from said terminal plates through said slits respectively into adjacent brush chambers and being connected to respective sides of said brushes.
