Abstract
Abstract A rectifier arrangement of an alternator for a vehicle includes a frame and a cover for a rectifier. The rectifier arrangement is composed of a plus-potential cooling-fin disposed in a space between the cover and the frame at a portion close to the cover in parallel therewith, a minus-potential cooling-fin disposed in the space in parallel with the plus-potential cooling-fin, a fastening member fixed to the frame and extending through mounting holes of the plus-potential and minus-potential cooling fins, a cylindrical bushing made of thermosetting resin disposed in a space formed by the cover, plus-potential cooling-fin and fastening member.
