To provide a vehicular drive device which scrapes an oil by rotation of a gear to supply the oil for lubrication to a lubrication object while reducing a loss of a gear mechanism caused by viscous resistance of the oil.SOLUTION: A vehicular drive device includes an axial oil guide passage 65 which captures an oil, scraped by a differential input gear 51 and dropping from an engagement portion Q between the differential input gear 51 and a second counter gear 42, and guides the oil to a tooth surface of a first counter gear 41 along an axial direction L along a third axis A3.SELECTED DRAWING: Figure 6
【課題】油の粘性抵抗によるギヤ機構の損失を低減しつつ、ギヤの回転によって油を掻き上げて潤滑用の油を潤滑対象に供給できる車両用駆動装置を提供する。【解決手段】差動入力ギヤ51により掻き上げられ、差動入力ギヤ51と第2カウンタギヤ42との噛み合い箇所Qより落下する油を捕獲して、第3軸A3に沿った軸方向Lに沿って第1カウンタギヤ41の歯面に油を導く軸方向導油路65を備える。【選択図】図6
