Abstract:
A brush assembly having improved wiring of an alternator for a vehicle, comprising a brush holder including a hollow brush holder body and a pair of wired brushes received in said brush holder body and adapted to be urged against a slip ring fitted around a rotor shaft by a spring along an axis of said slip ring, thereby coming into elastic contact with the slip ring to obtain an electrical connection to an external electrical device, each of the wired brushes including a brush and a lead wire electrically connected thereto, said brush holder body having a pair of brush channels each adapted to receive a respective one of said wired brushes, and a pair of wire channels each arranged at one side of an associated one of said brush channels and extending longitudinally in parallel therewith and communicating with said associated brush channel, the brush of each wired brush being received at a first end thereof in an associated one of said brush channels and elastically supported by the spring associated with the respective wired brush while being electrically connected at a fixing point with one end of the associated lead wire of the respective wired brush at said first end, each of said brushes being provided at said first end with an inclined surface having a desired inclination angle with respect to said fixing point, said fixing point being between the brush supporting end of said associated spring and said inclined surface, said inclined surface serving to prevent said associated lead wire from interfering with the respective brush during extension and retraction operations thereof.
