Abstract
An upright three-wheeled vehicle. A footboard unit is connected between the pair of rear wheel units. A handlebar unit extends from the frame. A bottom portion of a shaft of the handle unit is rotatably installed in a connecting frame. A fixed frame fixedly connects the front top surface of the footboard unit at both sides of the connecting frame. A first variable frame connected to an end of a shaft of the handlebar unit rotates the front wheel unit following the rotation of the shaft. A second variable frame is coupled to both ends of the first variable frame and fixed and installed on a central shaft of the front wheel unit. A shock absorbing means between the upper central portion of the second variable frame and the upper central portion of the first variable frame absorbs shocks by receiving forwardly biased force due to inertia when stopping.
