To provide a power transmission device capable of reducing a force acting in a direction orthogonal to a central axis line with respect to a power transmission mechanism when a rotary electric machine drives the power transmission mechanism.
The power transmission device 100 includes: an input shaft 5 which transmits power between a predetermined drive source; an output shaft 43 which is arranged in parallel to the input shaft, and transmits the power between a drive wheel; a counter shaft 34 which is arranged in parallel to the input shaft and the output shaft, respectively, and transmits the power between the input shaft and the output shaft, respectively; a rotary electric machine shaft 45 which is arranged in parallel to the input shaft, to which a rotor 26 of the rotary electric machine is connected; and the power transmission mechanism 23 which is provided in the input shaft concentrically with the input shaft, is engaged with the rotary electric machine shaft and the counter shaft, respectively, and transmits either the power of the input shaft or the power of the rotary electric machine shaft to the counter shaft. The central axis line C6 of the counter shaft and the central axis line C4 of the rotary electric machine shaft are positioned below the central axis line C3 of the input shaft in a vertical direction, respectively.
