[Object] To provide an electric three-wheeled vehicle in which the axial arrangement of a drive system is specially designed to
reduce the size of a power unit. [Constitution] In an electric three-wheeled vehicle 1 in which a rear body 30 including a motor M
as a source of power and a pair of left and right rear wheels WR is attached at the back of a body frame 2, the 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 from a vehicle forward side in the order of mention. The axis center 38a of the counter shaft 38 is located below a line L
connecting the axis center 36a of the motor output shaft 36 and the axis center 40a of the axle 40 in a side view of the vehicle.
