Abstract
An electrically-operated two wheeled vehicle provided with a swing unit which pivotally supports a drive wheel WR. The swing unit includes: a first rotary electric machine having a first rotor; a second rotary electric machine having a second rotor; and a planetary gear mechanism which combines a rotational drive force of the first and second rotors to each other and transmits a product of rotational drive forces to a drive wheel WR in a state where a rotational speed is increased. The first and second rotary electric machines are arranged parallel to each other in the longitudinal direction of a vehicle such that an axis Ax2 of the second rotor is positioned in front of an axis Ax1 of the first rotor along the vehicle body. This arrangement prevents a height position of a lower surface of a swing unit from becoming excessively low.
