<p>An electric vehicle 1, preferably a three-wheeled vehicle, has a motor M as a source of power and a pair of left and right rear wheels WR. Rotary driving power of the motor M is transmitted from a motor output shaft 36 to axles 40 of the rear wheels WR through a counter shaft 38. A centrifugal clutch 80 which transmits the rotary driving power to the counter shaft 38 when the revolution speed of the motor M exceeds a prescribed value is coaxially located at one end of the motor output shaft 36. The counter shaft 38 is located inside the outside diameter of the motor M in a side view of the vehicle. The motor output shaft 36, counter shaft 38, and axles 40 are arranged in that order from the front of the vehicle. The axis centre 38a of the counter shaft 38 is located below a line L connecting the axis centre 36a of the motor output shaft 36 and the axis centre 40a of the axle 40 in a side view of the vehicle. This allows the size of the power unit to be reduced.</p> |
