To obtain a vehicle electric driving device which enables a tooth surface of a hypoid gear to be lubricated easily and enables a motor to be cooled easily.SOLUTION: A vehicle electric driving device includes: a housing; a motor having a stator housed in the housing and a rotor housed in the housing; a first transmission mechanism housed in the housing; a pinion gear which is formed by a hypoid pinion and integrally rotates with an output shaft of the first transmission mechanism; and a differential gear having a ring gear, which is formed by a hypoid gear and engages with the pinion gear, the differential gear housed in the housing. The housing is provided with: a first housing chamber which houses the stator and the rotor and in which a first oil is placed; and a second housing chamber which houses the pinion gear and the differential gear and in which a second oil having viscosity higher than that of the first oil is placed.SELECTED DRAWING: Figure 2
【課題】ハイポイドギヤの歯面潤滑がされやすいとともにモータの冷却がされやすい車両用電動駆動装置を得る。【解決手段】車両用電動駆動装置は、ハウジングと、ハウジングに収容されたステータと、ハウジングに収容されたロータと、を有したモータと、ハウジングに収容された第1伝達機構と、ハイポイドピニオンによって構成され第1伝達機構の出力シャフトと一体に回転するピニオンギヤと、ハイポイドギヤによって構成されピニオンギヤと噛み合うリングギヤを有し、ハウジングに収容されたデファレンシャルギヤと、を備える。ハウジングには、ステータおよびロータを収容し第1オイルが入れられた第1収容室と、ピニオンギヤおよびデファレンシャルギヤを収容し粘度が第1オイルの粘度よりも高い第2オイルが入れられた第2収容室と、が設けられている。【選択図】図2
