ABSTRACT:
A slip ring is made of a carbonaceous material and a brush is made of a metal. A metal connection bar has an insert member held in the carbonaceous slip ring to make a mechanical and electrical connection without the necessity of an additional member. The slip ring and the connection bar are insert-molded in a slip-ring-support made of a resinous material. The slip-ring-support is press-fitted to a rear portion of the rotor so that the slip ring and the connection bar are fixed to the shaft at the same time. Further, the fan unit having a plurality of fan blades and a fan-supporting-portion is molded integrally with the slip-ring-support.
