Summary:Provided is a vehicle AC generator of high quality and high output with improved cooling efficiency of heat dissipating plates of a rectifier device. The vehicle AC generator comprises a stator comprising stator windings; front frame and a rear frame, each rotatably supporting a rotor in the stator via a space on an inner circumference thereof; a cooling fan fitted to the rotor; a first polarity arm configured to rectify a current of one polarity; a second polarity arm configured to rectify a current of another polarity; a rectifier device configured to rectify an alternating current generated in the stator windings; and a protective cover covering the rectifier device. The rectifier device comprises a first heat dissipating plate having a plurality of rectifier elements forming the first polarity arm, a second heat dissipating plate having a plurality of rectifier elements forming the second polarity arm, and a connection plate formed in a waveform-like shape and disposed between the first heat dissipating p
