PROBLEM TO BE SOLVED: To provide a vehicle driving device with two motors structured so that a speed reducer casing for parallely storing two speed reducers in a right and left direction is centrally placed and motor casings for two electric motors are fixed and arranged at left and right of the speed reducer casing, which reduces shaking of piping for inlet and piping for discharge which are connected to cooling paths of the motor casings for the two electric motors.SOLUTION: Cooling paths 4 through which is flown coolant are provided in left and right motor casings 3L and 3R respectively; coolant supply ports 5 of the cooling paths 4 are connected to a radiator by a piping 7 for inlet, and coolant discharge ports 6 of the cooling paths 4 are connected to the radiator by a piping 8 for discharge; and the piping 7 for inlet connected to the coolant supply ports 5 of the cooling paths 4 and the coolant discharge ports 6 of the cooling paths 4 are collected and supported at a center part of a speed reducer casing 20 by piping lock tools 10, so as to suppress shaking of the piping 7 for inlet and the piping 8 for discharge during travelling to the minimum.SELECTED DRAWING: Figure 2 |
