するものである。 Are there any known toy vehicles that adapt to uneven road surfaces that are equipped with endless tracks?
These traveling vehicles have a disadvantage of having a complicated structure and being relatively expensive to manufacture. Unlike the track type, this project has six wheels, and unlike the track type, the drive wheels themselves have a novel operation that adapts to uneven road surfaces, making the operation and its mechanism very appealing to children. The purpose is to provide a vehicle that is capable of providing sufficient performance.

十分魅力を与えるに足る効果がある。 Since the present invention is configured as described above, when the prime mover 11 is rotated by inputting the switch 24, for example, the large diameter intermediate gear 1 meshes with the output gear 12.
0, the transmission shaft 5 is rotated from the drive shaft 8 through the crown gear 9 and the pinion 6, and from this transmission shaft 5 the pinion 22, the intermediate transmission pinion 23, and the crown gear 2 are rotated.
1 to rotate the axle 18, and also operate the pinion 22 and crown gear 22 from the transmission shaft 5 to rotate the axle 1.
9, the front axle 15 is rotated via the pinion 13 and the crown gear 16, and the rear wheels 7, front wheels 14, and intermediate wheels 17 are driven at the same rotational speed, and the vehicle starts running. The three pairs of wheels are driven in this way, but since the chassis that includes the intermediate wheels 17 is supported by a movable chassis 3 that is separate from the chassis body 1, it is possible to move the front and rear wheels depending on the unevenness of the road surface. Even if the light is further away from the road surface,
The wheels attached to the movable chassis come into contact with the road surface and prevent the vehicle from tilting, so while the vehicle is moving up and down due to the unevenness of the road, the vehicle moves safely without tipping over. The drive provides a powerful propulsion force, so it can be easily propelled not only on rough roads but also on extremely steep slopes.Equipped with a conventional endless track, it has a novel running operation unlike a toy running car, and has a structure similar to that of an endless track. Since the mechanism is simpler than the formula, it is easy to manufacture, and the traveling operation in particular is effective enough to appeal to children and the like.
