To be able to dispose the transfer output shaft at essentially the center position in the vehicle width direction and to avoid the inability of arranging the propeller shaft in the floor tunnel.In a power transmission device of a four-wheel drive electrically driven vehicle, the power source includes a transverse engine (1) which is supported on one side surface (4a) of two side surfaces (4a, 4b) of a gear case (4), and a motor (2) which is supported on the other side surface (4b) and which is smaller than the transverse engine (1). A transfer (7A) is supported on the same side surface (4b) of the two side surfaces (4a, 4b) of the gear case (4) as the side surface (4b) on which the motor (2) is supported. The transfer (7A) has a transfer input shaft (71) that is arranged in the vehicle width direction, a transfer output shaft (74) that is arranged in the longitudinal direction of the vehicle, and a bevel gear pair (75) and a transfer gear pair (76) that transmit power by changing a direction of the axis of rotation to an essentially orthogonal direction between the transfer input shaft (71) and the transfer output shaft (74). An output shaft gear (76b) provided on the transfer output shaft (74) of the power transmission mechanism is disposed in a position overlapping the gear case (4) in a vehicle width direction.
