Abstract
In a differential device, first and second bearing bosses aligned on a same axis to be rotatably supported by a transmission case are integrally formed on one and another side portions of an integrated differential case housing a differential gear mechanism. Paired sleeves rotatably supported by the bosses are connected liquidtightly to paired left and right side gears of the mechanism. A tube portion is integrally protruded from an outer end of a hub of each gear. The sleeve is screwed and fastened onto an outer periphery of the tube portion. In the gear and sleeve, first and second sealing surfaces are formed respectively to closely adhere to each other by such screwing and fastening, thereby shutting off communication between an inside of the differential case and a screwed portion between the tube portion and sleeve.
