  • Publication number: 20100176684
    Abstract: An AC generator comprises a shaft, a rotor secured to the shaft, a stator with a stator core provided to surround the outer circumference of the rotor and having a plurality of slots formed to extend in the axial direction while spaced apart in the circumferential direction, and a front bracket and a rear bracket surrounding the stator core while clamping the circumferential edge portion of the stator core from the opposite sides in the axial direction using a plurality of clamping means. A pair of front stays formed in the front bracket are secured to a vehicle by means of bolts penetrating a pair of through holes formed, respectively, in the pair of front stays. The pair of through holes are formed at such positions as the perpendicular bisector of a line connecting the centers intersects the axis of the shaft, and one clamping means is provided on the shaft side perpendicular bisector.
