Therefore, when high-pressure air is injected through the air induction path 230 formed between the first endothelial 200 and the second endothelial 400, the air bag A is injected into the air bag A by the pressure of the injected air. Air is filled into the air bag A on both sides while the air inlets 240 and 440 formed on both sides are opened, and the air to be charged is charged to the lower portion of the air induction path 230 while being split fusion unit 250 in the center ( 450) to both sides.

Then, when the supply of air is stopped, the first endothelial 200 and the second endothelial 400 are brought into close contact with the air inlets 240 and 440 by the pressure of the air filled in both air bags A. There is no gap for the air to leak out.

Meanwhile, as shown in FIG. 17, the release part 230a may be formed on the bottom surface of the second endothelial 400.

In the above embodiment, the lower outer shell 100 has been fused to the upper outer shell 300 at the lower portion, and the first endothelial 200 is fused by placing the second inner shell 400 at the lower portion. It will be obvious that it is also possible to place them in reverse to the above description.
