<p><P>PROBLEM TO BE SOLVED: To provide a single-wheel cart towed by a two-wheeled vehicle, enabling smooth traveling around a curve. <P>SOLUTION: A support point for the towed single-wheel cart is provided in the vicinity of a shaft in a rear wheel left side in the advancing direction of the tractive two-wheeled vehicle. At this support point, movement in the rotating direction of wheels of the tractive two-wheeled vehicle and in parallel with the ground is freely enabled, but movement on a face perpendicular to the advancing direction is not enabled. Thus, a connection tool having a structure with the same inclination as that of the tractive two-wheeled vehicle is provided. The connection tool has a cylindrical shape to which a round bar part of a tip of the towed single-wheel cart is inserted and connected. The round bar part has a structure, all the time, in parallel with a plane on which the backmost wheel is rotated. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
