An electric vehicle capable of protecting a coupling portion between a wheel and an axle from disturbance. An electric vehicle includes an axle that is a hollow cylindrical shaft passing substantially coaxially through a wheel in a manner extending from both sides of the wheel. A motor shaft is inserted into a hollow portion of the axle substantially coaxially with the axle in a manner extending from both ends of the axle. In this case, a motor is connected to a base end of the motor shaft extending from one end of the axle. Between the wheel and the motor, there are provided a coupling portion for coupling between the one end of the axle and the wheel, and a labyrinth structure for sealing between the wheel and the motor in a manner surrounding the coupling portion. |
