To provide a vehicular drive device in which a transmission gear ratio of a first power transmission path from an internal combustion engine to a differential gear mechanism and a transmission gear ratio of a second power transmission path from a second rotary electric machine to the differential gear mechanism can be easily and individually set to optimum values.SOLUTION: A vehicular drive device 100 comprises: an input member 3; a pair of output members 8; a first rotary electric machine 1A and a second rotary electric machine 1B which are coaxially arranged; a first gear 2A which rotates integrally with the first rotary electric machine 1A; a second gear 2B which rotates integrally with the second rotary electric machine 1B; a third gear 4 which rotates integrally with the input member 3 and is meshed with the first gear 2A; a fourth gear 5 which is arranged coaxially with the input member 3 in such a manner that the fourth gear 5 rotates relative to the input member 3 and which is meshed with the second gear 2B; a differential gear mechanism 7 with a fifth gear 71; a first counter gear mechanism 6A which couples the third gear 4 and the fifth gear 71 in a drivable manner; and a second counter gear mechanism 6B which couples the fourth gear 5 and the fifth gear 71 in a drivable manner.SELECTED DRAWING: Figure 1

    【課題】内燃機関から差動歯車機構までの第1動力伝達経路の変速比と、第2回転電機から差動歯車機構までの第2動力伝達経路の変速比とを、個別に最適な値に設定することが容易な車両用駆動装置を提供する。【解決手段】車両用駆動装置100は、入力部材3と、一対の出力部材8と、同軸に配置された第1回転電機1A及び第2回転電機1Bと、第1回転電機1Aと一体的に回転する第1ギヤ2Aと、第2回転電機1Bと一体的に回転する第2ギヤ2Bと、入力部材3と一体的に回転し、第1ギヤ2Aと噛み合う第3ギヤ4と、入力部材3に対して相対的に回転するように入力部材3と同軸に配置され、第2ギヤ2Bと噛み合う第4ギヤ5と、第5ギヤ71を備えた差動歯車機構7と、第3ギヤ4と第5ギヤ71とを駆動連結する第1カウンタギヤ機構6Aと、第4ギヤ5と第5ギヤ71とを駆動連結する第2カウンタギヤ機構6Bと、を備えている。【選択図】図1
