PROBLEM TO BE SOLVED: To obtain an AC generator, for which the radial size of a rectifier can be reduced and the cooling efficiency of diodes fixed to a outside diameter- side heat sink can be improved. SOLUTION: A positive polarity-side heat sink 24 and a negative polarity-side heat sink 51 are arranged flat perpendicular with respect to a shaft, and positive polarity-side diodes 23 fixed to the inner heat sink 24 are arranged along the radial direction of the heat sink 24. In addition, negative polarity-side diodes 52 fixed to the outer heat sink 51 are arranged with their longitudinal directions in parallel with the peripheral direction of the heat sink 51. |
