PROBLEM TO BE SOLVED: To provide a power transmission device capable of supporting both sides in a shaft direction of an input shaft rotating member with a bearing while suppressing enlargement of the power transmission device. SOLUTION: The power transmission device includes: an input shaft 5; a first rotary electric machine shaft 17 disposed coaxially with an input shaft outwardly in a radial direction of the input shaft; a second rotary electric machine shaft 45; an input shaft rotating member 23 which is provided at a side opposite to a predetermined drive source 1 side rather than the first rotary electric machine shaft in the input shaft, and transmits the power of either the input shaft or the second rotary electric machine shaft to a drive shaft; and a case. The first rotary electric machine shaft is rotatably supported by the case via a plurality of bearings. An input shaft support bearing 51 at the predetermined drive source side is supported at an internal periphery of the first rotary electric machine shaft among the input shaft support bearings which support both sides in the shaft direction of the input shaft rotating member, as well as disposed in an area R between the bearing 53 at the most predetermined drive source side and the bearing 52 at a side being the furthest from the predetermined drive source among the bearings which support the first rotary electric machine shaft.
