PROBLEM TO BE SOLVED: To improve mountability on a vehicle, reduce sealing spots as well as pressure leakage and manufacturing cost, and to raise reliability. SOLUTION: This differential device is provided with a differential mechanism 21, a multiple disk clutch 45 for limiting differential motion, a hydrualic actuator 51 for operating the clutch 45, a case 3 for storing these equipment in its interior, and an oil pressure supply passage for supplying pressure oil to the actuator 51 from an oil pump arranged on the exterior of the differential case 3, and an oil passage 87, which is a part of the above mentioned oil pressure supply passage, is formed on a protrusion part 73 provided in the position overlapping with the outer side in the diameter direction of a bearing 5 supporting a boss part 71 of the differential case 3. |
