PROBLEM TO BE SOLVED: To provide a driving device of an electric vehicle capable of preventing the generation of noise in a low frequency band by suppressing vibration in the rotational direction of a motor.SOLUTION: The driving device of the electric vehicle includes a motor case 10 which houses a motor 9, a transmission case 41 which houses a transmission 42, and first case fixing means 100 and a second case fixing means 200 for fixing the motor case 10 to the transmission case 41. The first case fixing means 100 fixes the motor case 10 through a support plate 101 that absorbs the vibration of the motor case 10. Furthermore, the second case fixing means 200 fixes the motor case 10 via a coupling member 201 that is orthogonal to a rotating shaft 5 of the motor 9 and extends in radial direction to suppress vibration in the rotational direction of the motor case 10. |
