The cord body 13 is a cord-like body made of a high-tensile synthetic resin fiber. After being inserted in the insertion holes 11a and 12a in a meandering manner as described above, both ends are tied to each other to prevent them from falling off ( (Fig. 6). In addition, as the above-mentioned cord 13, any cord may be used as long as it has a necessary tensile strength.

In the framework structure a in the installed state, the lower ends of the columnar air chambers a1 and a2 are fitted into the openings of the stopper sheets 12 fixedly attached to the corresponding stationary positions p, respectively, and become the stationary positions p. Ground on the upper surface of the floor sheet c. In this state, the upper and lower stopper sheets 11, 12 overlap with each other, and the cord body 13 is meandering between the insertion holes 11a, 12a provided at regular intervals along the outer peripheral surface of the stopper sheets 11, 12.

The under stopper sheet 12 in the above embodiment is
The flange 12b provided around the lower end of the sheet 12 was fixed to the upper surface of the floor sheet c by bonding or sewing.
However, when the flange portion 12b is fixed by bonding, the area is small, and it is difficult to obtain a sufficient adhesive force. In addition, when sewing the flange portion 12b to the floor sheet c, the work is difficult because the floor sheet c is very large. However, as described above, the stop sheet 12
When the mounting seat 14 is sewn to the mounting seat 14 and then the mounting seat 14 is entirely adhered to the floor sheet c, the fastening strength of the stopper sheet 12 can be sufficiently secured by a wide adhesive area. At the same time, workability during manufacturing can be improved.
