In a small-sized electric vehicle in which a power unit 9 constructed by connecting an electric motor 15, a speed reduction device 23, and a differential device 29 in succession is supported on a vehicle body frame 2 via a suspension system 8, and right and left rear wheels 6r are secured to right and left rear axles 25 connected to an output part of the differential device 29, the suspension system 8 is constructed by a plate spring 40 whose front end part is fixed and cantilevered by the vehicle body frame 2, and a casing 10 for the power unit 9 is fixed to a rear end part of the plate spring 40 so that the driving reaction force of the power unit 9 is borne by the plate spring 40. Thus, there is provided a compact and inexpensive small-sized electric vehicle having a simple construction of suspension system enabling the vertical movement and rolling of the right and left rear wheels.
