To obtain a large transmission ratio in a drive device mounted with two units of vehicle drive electric motors while preventing the drive device from getting large in size.SOLUTION: A transmission mechanism 16 of a drive device 10 comprises: a first transmission path 46 which transmits output of a first electric motor 14 to a planetary gear mechanism 18; a second transmission path 54 which transmits the output of a second electric motor 16 to the planetary gear mechanism 18; a third transmission path 62 which transmits the output of the first electric motor 12 to the second transmission path 54; and a fourth transmission path 70 which transmits the output of the second electric motor 14 to the first transmission path 46. The transmission mechanism 16 also has: a first switching mechanism 72 which enables the output of the first electric motor 12 to be selectively transmitted to either the first transmission path 46 or the third transmission path 62; and a second switching mechanism 74 which enables the output of the second electric motor 14 to be selectively transmitted to either the second transmission path 54 or the fourth transmission path 70.SELECTED DRAWING: Figure 1

    【課題】2機の車両駆動用の電動機を備えた駆動装置において、装置の大形化を抑制しつつ、大きな変速比を得る。【解決手段】駆動装置10の変速機構16は、第1電動機14の出力を遊星歯車機構18に伝達する第1伝達経路46と、第2電動機16の出力を遊星歯車機構18に伝達する第2伝達経路54と、第1電動機12の出力を第2伝達経路54に伝達する第3伝達経路62と、第2電動機14の出力を第1伝達経路46に伝達する第4伝達経路70とを備える。さらに、変速機構16は、第1電動機12の出力を第1伝達経路46または第3伝達経路62に切り換え可能に接続する第1切り換え機構72と、第2電動機14の出力を第2伝達経路54または第4伝達経路70に切り換え可能に接続する第2期里替え機構74を備える。【選択図】図1
