<p>PURPOSE:To provide a motor-operated vehicle of two rear 7 wheels which rationalizes and uniformizes front and rear wheel load distribution through rational arrangement of a mounting device by means of an independent suspension type electric power unit, improves a maneuvering feeling and a riding feeling through reduction of the weight of a spring for rear wheels, improves the layout properties of a mounted apparatus, and improves running stability through lowering of the center of gravity of a vehicle. CONSTITUTION:A right and left independent suspension type electric power unit 16 is arranged to the central lower part of a car body frame 10 in a manner to be capable of swing. Rear wheels 17 are suspended from the rear end part of the electric power unit 16. The electric power unit 16 forms integral structure such that a drive motor 30, reduction gears 31 and 33, and a power transmission mechanism are formed integrally with swing arms 35. Meanwhile, a battery 26 is arranged below a driver seat 19 and between both swing arms 35.</p> |
