PROBLEM TO BE SOLVED: To provide a vehicle driving device with two motors in which loss of torque of a rolling bearing caused by induction thrust in a shaft direction is reduced in decelerators in two left and right rows.SOLUTION: The vehicle driving device with two motors comprises two electric motors 1L and 1R, and two decelerators 2L and 2R that decelerate individually driving force of the two electric motors 1L and 1R and transmits the force to left and right driving wheels. Gears of left and right gear rows constituting the decelerators 2L and 2R are formed of herical gears. Inboard sides of output gear shafts 25L and 25R are supported by rolling bearings 37a fitted into bearing fitting holes 35a constituted of through-holes provided at a partition wall 21 of a center casing 20a of a decelerator casing 20, and a thrust bearing 60 is provided between opposing shaft end surfaces of the left and right output gear shafts 25L and 25R.SELECTED DRAWING: Figure 1
