Among them, QuickBoard has recently been attracting more attention as a vehicle to which other humans provide driving force. The quick board is a quick board according to the prior art in which a skate boarding boarded by a passenger is provided in a streamlined quick board body as a play tool or a sports exercise apparatus so that the foot is tired by the foot.

In addition, in recent years, there have been proposed a first type quickboard that obtains a driving force that advances in such a manner that two foot plates are rotated on both sides of a center axis of transmission of a quick board body respectively, and a quick board in which two foot plates are stepped up and down alternately, A QuickBoard of the second scheme is emerging.

However, in the first method, there is a disadvantage in that the rotation radius is large and the feet are moved in different directions, thus causing a risk of accident. In order to apply the driving force, the restoration force is required to be solved by the occupant himself.

Various techniques for providing the restoring force in a manner of applying a force in the upward and downward directions have also been developed in the second method. However, there are problems in that the driving speed is lowered by providing restoring force, There has been a drawback.
