PROBLEM TO BE SOLVED: To provide a drive unit for a hybrid vehicle capable of setting various types of traveling modes.SOLUTION: A drive unit 10 is configured to divide driving force output by an engine 11 into a first motor 12 side and an output gear 16 side and add driving force output from a second motor 13 driven by electric power generated by the first motor 12 to driving force output from the output gear 16. A first planetary gear mechanism 14 performs a differential action by using a first input element 22 to which the driving force output from the engine 11 is input, a first reaction force element 23 connected to the first motor 12 and a first output element 24. A second planetary gear mechanism 15 performs a differential action by using a second input element 26 connected to the first output element 24, a second output element 27 connected to the output gear 16 and a second reaction force element 28. A first clutch mechanism 17 selectively couples the first input element 22 and the second reaction force element 28. A first brake mechanism 18 selectively fixes rotation of the second reaction force element 28.SELECTED DRAWING: Figure 1 【課題】多様な走行モードを設定できるハイブリッド車両用の駆動装置を提供する。【解決手段】駆動装置１０は、エンジン１１が出力した駆動力を第１モータ１２側と出力ギヤ１６側とに分割し、第１モータ１２が発電した電力で駆動される第２モータ１３が出力する駆動力を出力ギヤ１６から出力される駆動力に付加するように構成されている。第１遊星歯車機構１４は、エンジン１１が出力した駆動力が入力される第１入力要素２２と、第１モータ１２に連結されている第１反力要素２３と、第１出力要素２４とにより差動作用を行う。第２遊星歯車機構１５は、第１出力要素２４に連結された第２入力要素２６と、出力ギヤ１６に連結されている第２出力要素２７と、第２反力要素２８とにより差動作用を行う。第１クラッチ機構１７は、第１入力要素２２と第２反力要素２８とを選択的に連結する。第１ブレーキ機構１８は、第２反力要素２８の回転を選択的に固定する。【選択図】図１
