PURPOSE:To satisfactorily supply lubricating oil to each section of a power train while using a small oil pressure pump which consumes little electric power and lighten the power train. CONSTITUTION:The planet gears 42P and 44P of a speed reduction gear 16 comprising a pair of planet gear devices are integrated and rotatably supported by a common carrier pin 78, and the lubricating oil discharged from an oil pressure pump to an opening 72 is led to the carrier pin 78 through first lubricating passages 70, 74, and 76. The other sections of the speed reduction gear 16 and a differential device 18 are lubricated by the lubricating oil which gradually flows out from second lubricating oil passages 70, 84, 105, 104, and 106, which supply lubricating oil to the side of an electric motor positioned at the left, while flowing, and the lubricating oil supplied to the electric motor side returns to an oil pan 66 through a return oil passage 130 opened near the suction port 68 of the oil pressure pump. |
