To provide a three-wheeled vehicle having large toughness relative to falling down in which yawing instability hardly occurs.
A right rear wheel WRR of left and right rear wheels WRL, WRR of the three-wheeled vehicle is deviated to a rear side of a vehicle body than a left rear wheel WRL, and a position in a vehicle width direction of a front wheel WF is deviated to the right rear wheel WRR side than a center of gravity position G of the vehicle body. Therefore, distances D1, d2 from the center of gravity position G of falling down determination lines LL, LR connecting the front wheel WF and the left and right rear wheels WRL, WRR are enlarged as compared with the conventional three-wheel vehicle in which one front wheel WF and the left and right rear wheels WRL, WRR are arranged in symmetrical, thereby, toughness relative to falling down can be enhanced. Further, by providing the left and right rear wheels WRL, WRR, lateral force capable of being supported by the rear wheels WRL, WRR is sufficiently ensured as compared with the conventional three-wheel vehicle in which the left and right front wheels and one rear wheel are arranged in symmetrical, thereby, occurrence of yawing instability can be prevented.
