。The vacuum pump 3 of the vacuum pump direct-coupled generator is attached to the rear of the generator via a vacuum pump mounting seat l. Here, the vacuum pump mounting seat and the rear bracket 2 are held together only by a plurality of ribs 4, and a ventilation hole 5 is provided between the lower part of the vacuum pump mounting seat 1 and the rear bracket 2. When the generator is driven, cooling air 7 is sucked in by the fan 6 through the ventilation opening 5 and the ventilation 5a of the rear bracket 2. The cooling air 7 passes through the inner and outer peripheries of the rectifier heat sink 8 and exits to the front bracket 9. Thereby, the cooling air 7 that has passed through the ventilation port 5 cools the rectifying element 10, which is disposed inside the rear bracket 2 and substantially directly below the vacuum pump mounting seat l.

出来る．According to this embodiment, the overall cooling performance of the rectifier heat sink 8 can be improved, so that a high output of the generator can be obtained. Furthermore, by cooling the rectifying element 10, it is possible to improve the cooling performance of the soldered part 13 between the rectifying element lead 11 and the terminal 12 for connecting the rectifying element. Furthermore, by improving the cooling performance of the entire rectifying element, it is possible to extend the life of the rectifier. [Effects of the Invention] According to the present invention, by providing a ventilation hole between the lower part of the vacuum pump mounting seat and the bracket, the rectifying element that has been arranged inside the bracket and located almost directly below the vacuum pump mounting seat can be removed. Since the rectifying element can be actively cooled, it is possible to reduce the temperature rise of the rectifying element.
