Claim:
1. A differential device comprising a differential gear mechanism and an integrated differential case housing the differential gear mechanism therein, the differential case comprising: a case body; first and second bearing bosses formed integrally with the case body on a first side portion and a second side portion of the differential case, respectively, the first and second bearing bosses being aligned on a rotary axis and configured to be rotatably supported by a transmission case; a work window for receiving the differential gear mechanism therethrough, the work window being provided in a peripheral wall of the differential case; and a pair of sleeves supported by the first and second bearing bosses and connected to a pair of left and right side gears of the differential gear mechanism so as to overlap radially with each other in a liquid tight manner, wherein oil seals are disposed between outer end portions of the sleeves which protrude from the first and second bearing bosses and the transmission case, and left and right drive shafts are connected to the pair of side gears or to the sleeves, wherein the side gears are formed such that the associated drive shafts do not pass through the side gears axially, respectively, wherein the sleeves are configured to be capable of being passed through an inside of the differential case from the work window and slidably fitted and inserted to inner peripheries of the bearing bosses, sleeve retainers provided at outer peripheries of the overlapped portions of the sleeves and side gears, respectively, for preventing the sleeves from falling off outward in an axial direction thereof are provided between the sleeves and the first and second bearing bosses, and seal members for preventing lubricating oil in the differential case from flowing out of spaces between the side gears and the sleeves are provided between the side gears and the sleeves.
