PROBLEM TO BE SOLVED: To provide an electric automobile that allows a suspension device of each driven wheel to smoothly operate and can effectively suppress the vibration of the driven wheel when each driven wheel is individually driven by an electric motor. SOLUTION: When a rotating power of each electric motor 2 is transmitted to each driven wheel 1 and the automobile travels, a vehicle body 3 receives reaction torque of each electric motor 2 transmitted to the vehicle body 3 via a torque rod 14 and hence the suspension device of each driven wheel 1 smoothly operates. When the driven wheel 1 vibrates together with a lower arm 9 for suspending it vertically with respect to the vehicle body 3, the electric motor 2 supported on the lower arm 9 elastically via a coil spring 18 vibrates individually as a dynamic damper and hence the vibration of the driven wheel 1 can be suppressed.
