Claim Text:
1. A vehicle AC generator, comprising: a rotor provided on a shaft; a stator disposed so as to oppose the rotor; a rectifier rectifying current generated in the stator; a regulator adjusting voltage generated in the stator; and a resin cover covering the rectifier, wherein a partitioning section is integrally formed on the inner side of the resin cover; wherein the partitioning section extends in a peripheral direction and rises in an axial direction of the shaft, wherein the rectifier has a plurality of first diodes, respective heat generation sections of which are electrically connected to respective cathodes, and a plurality of second diodes, respective heat generation sections of which are electrically connected to respective anodes; and wherein the partitioning section extends so as to separate a first heat sink to which the cathodes of the plurality of first diodes are electrically connected, from a second heat sink to which the anodes of the plurality of second diodes are electrically connected.
