Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a hybrid-vehicular drive apparatus that allows no increase in a shaft length and prevents deterioration in noise-vibration performance or assemblability.SOLUTION: A hybrid-vehicular drive apparatus includes a secondary transmission mechanism configured as described below, the mechanism that is disposed between a stepless transmission and a drive wheel and is capable of realizing plural speed stages. That is, the mechanism includes: an input rotation element connected to an engine; an output rotation element connected to the drive wheel; a motor rotation element connected to a motor; first and second planetary gear sets, and first through third fastening elements. Further, the first planetary gear set is constituted as a planetary gear set that is capable of realizing a planetary direct connection function by fastening the first fastening element and a reverse function by fastening the second fastening element, and the second planetary gear set is constituted as a planetary gear set having a fixing element and capable of realizing a deceleration function, and the input rotation element is connected to or disconnected from the motor rotation element by the third fastening element. 【課題】軸長が増大することなく、かつ、音振性能の悪化や組み立て性の悪化を招くことのないハイブリッド車両の駆動装置を提供すること。【解決手段】本発明によるハイブリッド車両の駆動装置は、無段変速機と駆動輪との間に配置され複数の変速段を達成可能な副変速機構を以下のように構成した。すなわち、エンジンと接続された入力回転要素と、駆動輪と接続された出力回転要素と、電動機と接続された電動機回転要素と、第1及び第2遊星歯車組と、第1，第2及び第3締結要素と、を有し、第1遊星歯車組を第1締結要素の締結による遊星直結機能と第2締結要素の締結による逆転機能とを達成可能な遊星歯車組とし、第2遊星歯車組を固定要素を有し減速機能を達成可能な遊星歯車組とし、第3締結要素によって入力回転要素と電動機回転要素とを断接することとした。【選択図】図２
