Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power transmission device which can be compactly mounted on a hybrid vehicle, by achieving downsizing of a clutch structure.SOLUTION: A power transmission device 10 which transmits rotational power of an engine 110 mounted on a vehicle 100 and a rotary electric machine 120 to driving wheel 101 side includes: a friction clutch 15 for transmitting or cutting off the rotational power of the engine; an engaging clutch 16 for transmitting or cutting off the rotational power of the rotary electric machine; and an actuator 17 for sliding a piston member 41 for allowing these clutches to function into one direction. The piston member is positioned in a first stroke position for bringing the friction clutch into a cut-off state and bringing the engaging clutch into a transmission state, a second stroke position for bringing both the friction clutch and the engaging clutch into the transmission state and a third stroke position for bringing the friction clutch into the transmission state and bringing the engaging clutch into the cut-off state.SELECTED DRAWING: Figure 1 【課題】クラッチ構造の小型化を実現することにより、ハイブリッド車両にコンパクトに搭載可能な動力伝達装置を提供すること。【解決手段】車両１００に搭載のエンジン１１０および回転電機１２０の回転動力を駆動輪１０１側に伝達する動力伝達装置１０であって、エンジンの回転動力を伝達または遮断する摩擦クラッチ１５と、回転電機の回転動力を伝達または遮断する噛み合いクラッチ１６と、これらクラッチを機能させるピストン部材４１を一方向にスライドさせるアクチュエータ１７とを備え、ピストン部材は、摩擦クラッチを遮断状態にして噛み合いクラッチを伝達状態にする第１のストローク位置と、摩擦クラッチおよび噛み合いクラッチの双方を伝達状態にする第２のストローク位置と、摩擦クラッチを伝達状態にして噛み合いクラッチを遮断状態にする第３のストローク位置とに位置される。【選択図】図１
