The member 9 is disposed at the center of the floor structure body 10 and in the longitudinal direction, and both ends of the rotation center shaft member 9 are fixed by being inserted into the front and rear walls 8, 8.

The peripheral surface of the floor structure body 10 is a surface according to the purpose. That is, one surface is a carpet surface portion 12 on which a carpet 12a is adhered, and another surface is a floor plate surface portion 1 having a floorboard.
3. The remaining one surface is a seat surface portion 14 on which a seat 15 is provided.

As shown in FIG. 2, a plurality of seats 15 are arranged side by side in the longitudinal direction of the floor structure body 10, and each seat 15
Is opened by its weight by a generally used mechanism, that is, while the spectator is on the pedestal portion, and the pedestal closes (folds) when the spectator stands.

The seat surface portion 14 of the floor structure main body 10 is divided into two parts, and includes a support plate 16 on which the seat 15 is mounted, and a footrest plate 17 corresponding to a portion on which a spectator places a foot.
The base end of the support plate 16 and the base end of the footrest plate 17 are rotatably supported via hinge members 18, 18, respectively. A pair of cylinder devices 24 and 25 for opening and closing the support plate 16 and the footrest plate 17 are mounted between the 10 carpet surface portions 12 and the back surface of the floor plate surface portion 13.

A drive motor 21 connected to the rotation center shaft member 9 through a power transmission mechanism 20 to rotate the floor structure body 10 around the rotation center shaft member 9 is provided by the floor structure body 1.
