Document Type and Number:
WIPO Patent Application WO/2016/079867
Kind Code:
A1
Abstract:
The present invention provides an AC generator for vehicles, that is capable of increasing rectifying element reliability and generator cooling properties and of reducing the axial direction dimensions of a rectification device. This rectification device (30) has a configuration whereby: a circuit board (40) has a first rectifying element connection section (42) and a second rectifying element connection section (41) and is arranged between a first rectifying element holding section (32) and a second rectifying element holding section (36); a plurality of first rectifying elements (28) are each held by the first rectifying element holding section (32), extend a first lead electrode (28b) in the axial direction, and connect same to the first rectifying element connection section (42); the plurality of second rectifying elements (29) are each held by the second rectifying element holding section (36), extend a second lead electrode (29b) in the axial direction, and connect same to the second rectifying element connection section (41); and a radial direction ventilation passage connecting the rectification device (30) in the radial direction is arranged separating the circuit board (40), in the axial direction, from at least either the first rectifying element holding section (32) or the second rectifying element holding section (36).
