Alternator for vehicle

摘要

In an alternator, a brush holder holds a pair of brushes which abut slip rings perpendicularly. The brush holder is disposed within an inner periphery of a cooling fan so that the brush holder overlaps with the cooling fan in the axial direction by approximately a width of a brush. The brush holder is secured to the rear housing and disposed to face an air intake window. As a result, the axial length of the alternator is reduced without sacrificing cooling capacity for the brushes.
