Abstract
Provided is an electric vehicle that is easy to start to move even when there is load applied, and which does not generate rotational resistance of the electric motor when the vehicle is push-walked. A connection/disconnection mechanism is provided between the electric motor (50) and the speed reducing mechanism (70) to switch transmission of the rotating driving force from a disabled state to an enabled state when the electric motor (50) rotates at a predetermined rotation speed or more. The connection/disconnection mechanism is a centrifugal clutch (40). The swing arm (12) is configured as a cantilever-type, supported only at the left side in the vehicle width direction, so that the centrifugal clutch (40), the electric motor (50), and the speed reducing mechanism (70) are arranged in this order, from the left side in the vehicle width direction.
