To provide a vehicle power transmission device which uses a rotary electric machine as a driving source, obtains larger power, and effectively performs regeneration without enlarging the device.SOLUTION: A vehicle power transmission device includes: a first rotary electric machine (MG1) serving as a power source; an input shaft (IS) in which the first rotary electric machine (MG1) is disposed; a non-stage transmission (TM) connected to the input shaft (IS); a planetary gear mechanism (PG) including a first rotation element (31) connected to the input shaft (IS), a second rotation element (32) connected to the non-stage transmission (TM), and a third rotation element (33) with which the first rotation element (31) and the second rotation element (32) are connected; an output shaft (OS) connected to the planetary gear mechanism (PG); and a differential mechanism (DF) connected between the output shaft (OS) and a driving shaft (WS). The second rotary electric machine (MG2) is disposed in the output shaft (OS).SELECTED DRAWING: Figure 1
