Zusammenfassung:	The disclosed vehicle drive device (10) includes: motor housings (11,12), a gearbox housing (13), an inverter case (14), and a PN line (9). The motor housings (11,12) form respective exteriors of a left motor (1) and a right motor (2) that drive left and right wheels of a vehicle with electric power of a battery. The gearbox housing (13) incorporates therein a gearbox (3) that amplifies torque of the left and right motors and that transmits the amplified torque to the left and right wheels, is sandwiched between the left and right motor housings (11,12), and is offset in a front-rear direction from the left and right motor housings (11,12). The inverter case (14) incorporates therein a pair of semiconductor modules (6,7) and is arranged above the left and right motor housings (11,12). The PN line (9) connects the battery to the semiconductor modules (6,7) from a lower surface side of the inverter case (14) so as to pass through a first space (41).
