Zusammenfassung:	To provide a hybrid drive device capable of preventing reverse rotation of an oil pump, as well as, capable of transmitting driving force to wheels.SOLUTION: Upon determining that an input shaft rotation speed Nin is reversed, a control unit of a hybrid drive device controls a start clutch WSC to come into a slip-engaged state, while executing normal rotation maintenance control for controlling a motor so that a rotor rotation transmission member rotates in a normal direction. Thereby, driving force of the motor can be transmitted to wheels while the reverse rotation of an oil pump can be prevented, and for example, it is possible to prevent the vehicle from accelerating sliding down.SELECTED DRAWING: Figure 4 【課題】オイルポンプの逆回転を防止し、かつ車輪に駆動力を伝達することが可能なハイブリッド駆動装置を提供する。【解決手段】ハイブリッド駆動装置の制御部は、入力軸回転速度Ｎｉｎが逆転することを判定した場合に、発進クラッチＷＳＣをスリップ係合状態に制御すると共に、ロータ回転伝達部材が正転回転となるようにモータを制御する正転維持制御を実行する。これにより、オイルポンプの逆回転を防止することができるものでありながら、車輪にモータの駆動力を伝達することができ、例えば車両のずり下がりが加速してしまうことを防止することができる。【選択図】図４
