Abstract
A vehicle alternating current generator increasing the flow of cooling air therethrough and reduces whizzing sounds from cooling windows surrounding the generator's fan. This is done by inclining guide walls separating the cooling windows so that the angle of inclination thereof in the radial direction of the generator is larger the closer the windows are to the forward edge of the housing supports and smaller the closer the windows are to the backward edge of the housing supports. Also, the cooling windows narrow the closer they are to the supports, and are widest in the middle between two adjacent supports. Further, the axial length of the windows may be shorter the closer they are to the supports, and longer in the middle between two adjacent supports.
