この考案は、自動車玩具における後輪の懸架装
置に関する。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a rear wheel suspension system in a toy car.
（従来の技術）
走行可能な自動車玩具に懸架装置を設けること

玩具の後輪における懸架装置にあつては、従来、
動力源であるゼンマイ等を搭載する必要上、後輪
の懸架装置を設けることは、メンテナンス上無理
があつた。(Prior Art) A suspension system is installed in a toy car that can run, but in this case, the current situation is that a sufficient suspension system is not installed due to the space limitations of the toy or the limitations on the shape of the parts. . For example, regarding the suspension system for the rear wheel of the toy, conventionally,
Due to the need to mount a power source, such as a mainspring, it was impossible to install a suspension system for the rear wheels in terms of maintenance.
そこで、上記した点も鑑みなされた後輪懸架装
置が、実公昭51−15793号公報に提案されている。
この種の提案例は、モータを取付けた取付台を締

た。 Therefore, a rear wheel suspension system that has been developed in consideration of the above-mentioned points has been proposed in Japanese Utility Model Publication No. 15793/1983.
An example of this type of proposal is to use the flexibility of the chassis by fixing the mounting base on which the motor is attached to the rear chassis of a racing car through a tightening means, so that the rear wheels can be seen from the running surface. It functioned as a shock absorber for the rear wheels, mitigating and absorbing the impact they received.
（考案が解決しようとする問題点）
しかしながら、斯かる後輪の懸架装置にあつて

好ましくなかつた。(Problem to be solved by the invention) However, in the case of such a rear wheel suspension system, since the mounting base is fixed to the flexible chassis part by a tightening means, it is difficult to hold a toy car. When running for a long time, the bending moment applied to the base of the chassis piece is constantly applied to the base of the chassis piece, and as a result, there is a risk that the chassis piece may break from the base, which is undesirable and Ta. In addition, when the toy is running, the ability of the rear wheels to follow the road surface is poor because the only action that moves the rear wheels toward the road surface is the flexibility of the chassis. enough is enough;
I didn't like it.

装置を提供することを目的とする。 Therefore, the purpose of the present invention is to be able to increase the strength of the rear wheel suspension system in a toy car, and also to increase the ability of the rear wheels to follow the running surface, thereby increasing the strength of the toy car. It is an object of the present invention to provide a rear wheel suspension system for a toy car that can also improve the performance.

る。 First, with the toy car 1 placed on a flat surface, the infant holds the toy 1 in his hands and moves it backwards, winding the mainspring or the like in the gear case 2 to secure driving force. At this time, since young children cannot measure the amount of force applied to the toy, they always apply force to the toy 1 in the direction of a flat surface, but the rear wheel suspension system 15 of the toy 1 is in the state shown in FIG. When a force is applied to the toy 1 as shown by arrow A in FIG. 4, the coil spring 17 fitted in the rod 16
is contracted, and the front end of the gear case 2 and the rear part of the chassis 3 flexibly move downward using the front end of the gear case 2 as a fulcrum, so that the force in the direction of arrow A in FIG. 4 can be relaxed and absorbed.
