PROBLEM TO BE SOLVED: To provide smoother revolution property of an electric vehicle and to improve revolution operability much more while a real current of an electric motor on a revolution outer side is suppressed. SOLUTION: An airframe 19 of the electric vehicle 10 is provided with left and right travel devices 11L and 11R, left and right electric motors 21L and 21R driving the travel devices, a control unit 61 controlling speeds of the electric motors by using currents, and revolution operation members 43L and 43R performing a left revolution operation or a right revolution operation so as to emit revolution commands of the left and right travel devices to the control unit. When the left or right electric motor revolving by the revolution operation of the revolution operation member is set to be a revolution inner motor, and the other is set to be a revolution outer motor, the control unit decelerates the revolution inner motor and controls a real current of the revolution outer motor to be a target current at the time of the revolution operation by the revolution operation member, when there is the revolution operation of the revolution operation member.
