Abstract
A peripheral flange formed on a differential case for mounting a ring gear and the peripheral flange is provided with a plurality of cast-in bolt holes for bolting up the ring gear to the differential case using the lost foam casting process for making the differential case. A method of making a gear case eliminates the process of machining of the bolt holes in the differential case casting, thus reducing cost of manufacturing the differential case.
