In this case, the supporting cylindrical body 7 and the other components 6 are individually manufactured, and these components are later fixed to each other to be integrated, so that each component can be easily processed. That is.

Therefore, according to the present embodiment, since the floor panel 1 is supported in a state in which many parts of the floor support legs 2 are accommodated in the hole 8 of the floor panel 1, the underfloor with a low floor height is provided. It has a ground structure, and as a result, a large living space for the room can be secured. Further, since the structure for supporting the floor panel receiver 5 by screwing it into the support bolts 4 does not cause rattling of the floor panel receiver 5, the extra parts such as locking means are not required for assembly. It can be done easily and quickly, and has excellent economical efficiency and workability.

On the other hand, since the nylon plate 9 is interposed between the support 3 and the bolt head 4a of the support bolt 4 to smoothly rotate the support bolt 4, the height can be easily adjusted. .. Further, since the support body 3 and the support bolt 4 are assembled by fitting, they can be easily removed. This is convenient because it can be easily replaced when it is desired to change the hardness of the elastic body of the support 3. Further, due to the elastic effect of the support 3 placed on the floor slab surface 13 of the floor support leg 2, the impact applied to the floor panel 1 can be effectively alleviated and the impact noise can be suppressed.
