PURPOSE:To provide a compact tri-axial automatic transmission without any power loss impairment by disposing a forced lubrication system comprising a lubrication oil strainer, a jet and an orifice in the differential mechanism. CONSTITUTION:In the differential mechanism, a forced lubrication system is provided that comprises a lubrication oil strainer 1 connected to a secondary regulator valve 4, a jet 2 connected to the lubrication oil strainer 1 and an orifice 3. The lubrication oil filtered by the oil strainer 1 is injected from the jet 2 to differential gears and is supplied to a side bearing (b) through the orifice 3. Therefore, as the lubrication of the differential gears and side bearing are adequately done, and the amount of the lubrication oil can be reduced, a tri-axial automatic transmission can be made compact without any power loss impairment.
