<p>To provide an electric vehicle capable of protecting a coupling portion between a wheel and an axle from disturbance. An electric vehicle (10) includes an axle (52) that is a hollow cylindrical shaft passing substantially coaxially through a wheel (90) in a manner extending from both sides of the wheel (90). A motor shaft (16a) is inserted into a hollow portion of the axle (52) substantially coaxially with the axle (52) in a manner extending from both ends of the axle (52). In this case, a motor (16) is connected to a base end of the motor shaft (16a) extending from one end of the axle (52). Between the wheel (90) and the motor (16), there are provided a coupling portion (192) for coupling between the one end of the axle (52) and the wheel (90), and a labyrinth structure (190) for sealing between the wheel (90) and the motor (16) in a manner surrounding the coupling portion (192).</p> |
