A power transmission device for a hybrid vehicle is disclosed. According to an embodiment of the present invention, the power transmission device for a hybrid vehicle removes a mechanical backward gear of a transmission and reduces a wet type clutch to be maximally simplified, improves power transmission efficiency through various shifting modes such as a multi-stage engine mode, a parallel hybrid mode, and an electronic non-stage shifting mode (an eCVT mode), and an electric vehicle mode (an EV mode), reduces cost, and realizes fuel efficiency and power performance better than an equivalent transmission. 하이브리드 차량용 동력전달장치가 개시된다. 본 발명의 실시 예에 따른 하이브리드 차량용 동력전달장치는 변속기의 기구적인 후진 변속단을 삭제하고 습식 클러치를 축소하여 최대한 단순화하면서 다단의 엔진 모드와 패러렐 하이브리드 모드, 및 전자적 무단변속 모드(eCVT 모드)와 전자자동차 모드(EV 모드) 등의 다양한 변속 모드로 동력전달효율을 개선하며, 원가 절감 및 동등 변속기 이상의 연비 및 동력 성능을 구현한다.
