Provided is an electric vehicle that realizes a light electric straddled vehicle using a motor with a small size, and optimizes the left and right weight balances in the width direction of the vehicle with respect to the vehicle body centerline. The electric motor () is disposed inside a swing arm () of a cantilever type at a position overlapping a projection area of a rear wheel WR when seen from the side portion of the vehicle body. The motor driver () is disposed inside the swing arm () so that the vehicle body centerline (C) passing through at the front side of the vehicle body in the rear wheel (WR). The position (G) of the center of gravity of the motor driver () is disposed to be offset in the direction opposite to the offset direction of the electric motor () with respect to the vehicle body centerline (C).

Electric straddled vehicle

In an electric three-wheeled vehicle, a centrifugal clutch transmits rotary driving power to a counter shaft when the revolution speed of a motor exceeds a prescribed value. The clutch is coaxially located at one end of a motor output shaft. A counter shaft is located inside the outside diameter of the motor in a side view of the vehicle. The motor output shaft, counter shaft, and axles are arranged from a vehicle forward side in the order of mention. The axis center of the counter shaft is located below a line connecting the axis center of the motor output shaft and the axis center of the axle in a side view of the vehicle.

Electric vehicle

An electric motor and a differential mechanism are placed near a vehicle body left-right center line distributed between the left and right sides of the vehicle body. In addition, at least parts respectively of the electric motor and the differential mechanism are placed on the vehicle body left-right center line. A deceleration mechanism is placed away from the vehicle left-right center line on one of the left and right sides of the vehicle.

Electric three-wheel vehicle

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 () and the speed reducing mechanism () to switch transmission of the rotating driving force from a disabled state to an enabled state when the electric motor () rotates at a predetermined rotation speed or more. The connection/disconnection mechanism is a centrifugal clutch (). The swing arm () is configured as a cantilever-type, supported only at the left side in the vehicle width direction, so that the centrifugal clutch (), the electric motor (), and the speed reducing mechanism () are arranged in this order, from the left side in the vehicle width direction.
