Not only is it labor-intensive, resulting in low productivity and high costs, but it also has defects such as the number of welded wires inevitably increasing to create an airtight seal, which is undesirable in appearance. The manufacturing equipment of the second type was a large one, making it unsuitable for small-volume production of a wide variety of products, and it had defects such as lack of stability in production.

成するものである。Next, an embodiment of the present invention will be explained with reference to FIG. A circular bottom plate (1) made of thermoplastic soft synthetic resin film commonly known as Noshi, a circular intermediate plate (3) made of the same film with ventilation holes (2), and a supply/exhaust plug (4) are installed. Each plate + 1) (

Afterwards, these were the bottom plate (1), middle plate (3), and top plate (

直二行う。Normally, each plate m i31 (5) is cut into two circles at the same time by the above-mentioned high-frequency hermetic welding process, which is commonly called burn-cutting.

注射針等で送気する所謂ヘソな利用することがある。The present invention may be carried out without adding the tin (6) mentioned above, and an ordinary soft synthetic resin film may be used for the intermediate plate (3). ≦There is a so-called belly button use where air is supplied with two injection needles, etc.
本発明は上記のような構成であるので使用ｇ１際しては

るものである。Since the present invention has the above-mentioned configuration, when it is used, air is supplied from the supply/exhaust valve to expand the spherical g2, and when it is not used, it is expanded.
The second method is to exhaust the gas and leave it in a crushed state.

波状に曲ったシすることを防ぐようＣ二作用する。As shown above, the two are spherical; when inflated, the top plate and the bottom plate expand into a hemispherical shape due to internal pressure, as shown in Figures 3 and 4. The intermediate plate functions like a hanger to prevent the spherical shape from being distorted and the welded wire (7) from becoming wavy.

い効果を有するものである。The present invention is as described above: A circular bottom plate made of a thermoplastic soft synthetic resin film with remarkable elasticity, a circular intermediate plate made of the same film with ventilation holes, and the same film to which an air supply/exhaust plug is attached. The feature is that the entire periphery of the circular bottom plate is welded to the circular bottom plate, so that it has an excellent effect of fully achieving the above-mentioned intended purpose. Further ≦2 The balls obtained from the above-mentioned bamboo leaf-like pieces and the balls obtained from the hemispherical pieces made by vacuuming were made of ordinary vinyl, so the face plate had poor elasticity, the repulsive force as a ball was weak, and it was difficult to use by hand. Since it is made of a thermoplastic soft synthetic resin film that is stretchable to the touch, it has a strong repulsive force as a ball and has favorable effects such as a soft feeling when touched by hand.
