PROBLEM TO BE SOLVED: To stabilize a vehicle by restraining the center of gravity height of a vehicle drive device, which increases the weight by incorporating a torque difference amplifier 30, to be low while preferably supplying tube oil into a planet gear Pof the torque difference amplifier 30.SOLUTION: Intermediate gear shafts 13L and 13R of reduction gears 3L and 3R incorporating the torque difference amplifier 30 are disposed at the lowest position from the ground surface among gear shafts constituting the reduction gears 3L and 3R so as to restrain the center of gravity height of the vehicle drive device to be low; and the oil level of lube oil included in a reduction gear housing 9 is set at a height in which a planet gear of the torque difference amplifier 30 located at lowest point immerses in a vehicle stopping state.SELECTED DRAWING: Figure 5 【課題】 トルク差増幅装置３０の遊星歯車ＰLの内部への潤滑油の供給を良好に行うことができ、しかも、トルク差増幅装置３０を組み込むことにより重量アップした車両駆動装置の重心高さを低く抑えることにより、車両の安定性を図る。【解決手段】 トルク差増幅装置３０を組み込む減速装置３Ｌ、３Ｒの中間歯車軸１３Ｌ、１３Ｒを、減速装置３Ｌ、３Ｒを構成する各歯車軸の中で、地面から最も低い位置に配置し、車両駆動装置の重心高さを低く抑えるようにし、減速装置ハウジング９内に封入される潤滑油の油面を、停車状態で前記トルク差増幅装置３０の最下点に位置する遊星歯車が浸漬する高さに設定した。【選択図】 図５
