PURPOSE: To eliminate the necessity of rising/lowering of an auxiliary wheel by providing a pair of left and right arms firmly connected to each other by a connecting shaft and using an auxiliary wheel assembly where the connecting shaft is supported to be turned around an axis extended in the horizontal direction of a two-wheel vehicle. CONSTITUTION: For driving at a speed faster than a low speed, when a pressure applied to a lever 44 by a food pad 54 is released, an arm 28 and the lever 44 are disengaged from each other, and wheel support arms 26 and 28 are freely turned around the axis 34 of a connecting shaft 30. At this time, one or both of auxiliary support system wheels 38 and 38 are brought into contact with the ground. For running at a low speed for gradual slowing-down or stopping, the tip of the lever 44 is lowered by the pressure of a foot applied to the foot pad 54 and engaged with the arm 28, and the turning movements of the arms 26 and 28 around the axis 34 are fixed. Then, the arms 26 and 28 are fixed in specified positions, and the vehicle is stabilized and its inclination is prevented. |
