Abstract: PROBLEM TO BE SOLVED: To smoothly and safely clear a curve without generating a fall even at the time of entering the curve at a high speed, and to simplify the structure for adjusting a space between axles by dividing a connecting rod for connecting front wheels and rear wheels on the way thereof, and fitting a zoom mechanism to the divided position. SOLUTION: A connecting rod 11 is cut on the way thereof so as to form connecting rods 11A, 11B, and these rods are connected by an operator 12. The operator is formed with a screw so that the right and left connecting rods come close to each other when the operator 12 is turned in one direction in relation to the right and left connecting rods 11. When the operator 12 is turned in a direction X (right), the connecting rods 11A, 11B come close to each other, and when the operator 12 is turned opposite to the direction X, both the connecting rods 11A, 11B are separated from each other. Since a front wheel frame 8 and a rear wheel frame 6 are integrally fitted to the connecting rods 11, a space between axles of the front wheels 1 and the rear wheels 2 is narrowed or widened so as to function as a zoom mechanism.  With this structure, adjustment of a space between axles is simplified, and a vehicle can smoothly enter a curve.

Glass, light transmitting ceramics, light transmitting resin, transparent paper and the like are used for the molding frame. When the whole of the molding frame is provided with light transmittancy, light can be radiated on the resin content over the entire surface of the molding frame, therefore, uneven light radiation will never be generated and the amount of radiated light is large whereby a time necessary for polymerizing process can be greatly shortened. When the molding frame is so constituted that a pressure is applied on the resin content at all times, the dimensional accuracy of the resin molded form, whose volume is changed in accordance with the photopolymerization, can be surely maintained.
