Patent ID: 8820449

Claim:
An electric vehicle in which an output of a motor is transmitted to an axle through a reduction mechanism in order to rotate a wheel, wherein: the axle, which is slidably fitted to the wheel, passes through the wheel, and is substantially coaxially connected to the wheel for common rotation therewith, is a hollow cylindrical shaft; a brake for braking rotation of the wheel; the motor has a motor shaft inserted into and through the hollow cylindrical shaft substantially coaxially with the cylindrical shaft so as to extend from first and second ends of the hollow cylindrical shaft; wherein, on a first side of the wheel, the motor is connected to a base end of the motor shaft extending from the first end of the hollow cylindrical shaft; on a second side of the wheel, the reduction mechanism is connected to a leading end of the motor shaft that projects from the second end of the hollow cylindrical shaft; and the reduction mechanism rotates the hollow cylindrical shaft and the wheel in accordance with rotation of the motor shaft caused by driving of the motor; wherein the brake is disposed on the second side of the wheel, surrounds the axle and the motor shaft, and is disposed relatively between the wheel and the reduction mechanism.
