Abstract
An alternator for motor vehicles having a housing for holding a stator between front and rear brackets comprising side mounting sections formed integrally with the front and rear brackets and having mounting holes to be directly mounted to an engine by mounting tools, wherein each mounting hole comprises at least three U-groove holes formed by a trimming die, provided through in a direction perpendicular to an axial direction of a rotary shaft of the alternator, and are opened in the same axial direction as the rotary shaft, the three holes being opened alternately in opposite directions one by one; and wherein at least one of the side mounting sections has positioning holes for positioning circumferentially the front and rear brackets provided through the mounting holes in the axial direction of the rotary shaft. Since the alternator has the mounting holes of superior vibration resistance formed by the trimming die in a casting, the number of working steps of the housing may be reduced and any defect in the manufacturing of the positioning holes associated with the mounting holes is prevented. As a result, the quality of the housing is improved.
