A power transmission device of a hybrid electric vehicle comprises an engine, a first driving motor and a second driving motor, a first gear and a second gear are fixed to a first solid shaft in the circumferential direction, a third gear is fixed to a first hollow shaft in the circumferential direction, an idler gear is arranged on a second solid shaft in a clearance fit mode, and a fourth gear is fixed to the second hollow shaft in the circumferential direction. A fifth gear and a sixth gear are fixed to a third solid shaft in the circumferential direction, and a seventh gear is fixed to a third hollow shaft in the circumferential direction. The first gear is meshed with a seventh gear, the second gear is meshed with a fourth gear, the third gear is meshed with the fifth gear, an idler gear is meshed with the sixth gear, and the sixth gear is further meshed with the input gear of a differential mechanism. A first clutch is arranged between the second solid shaft and the second hollow shaft; a synchronizer is arranged between the idle gear and the first clutch and is circumferentially fixed with the second solid shaft; and a second clutch is arranged between the third solid shaft and the third hollow shaft.
