うに形成することができるものである。 In the tatami having the above-mentioned structure, the cushion plate 5 is laminated on the surface reinforcing plate 4, and the cushion plate 5 constitutes the top layer of the tatami floor 1, so the cushion plate 5 ensures the surface feel of the tatami. At the same time, dynamic locally concentrated loads are absorbed by the surface reinforcing plate 4 in a state close to a substantially uniformly distributed load, resulting in excellent surface feel and
It has a feeling of use. In particular, the foam substrate 2
is formed to have a specific gravity of 0.2 to 0.8 and a thickness of 20 to 40 mm, and a molded fiberboard 3 is formed to have a specific gravity of 0.15 to 0.4 and a thickness of 10 to 30 mm.
The surface reinforcing plate 4 is made of a rigid material and has a thickness of 2 to 5 mm, and the cushion plate 5 has a specific gravity of 0.3 to 0.6 and a thickness of 3 mm.
By making it harder than the foam substrate 2 with a thickness of ~10 mm, it can be formed to have the elasticity and surface feel unique to straw tatami.

合成畳表を用いることが好適である。 Furthermore, in the tatami having the above-described structure, the surface reinforcing plate 4 is laminated on the upper side of the foam substrate 2 and the molded fiberboard 3, and the back reinforcing plate 6 is laminated on the lower side of the foam substrate 2. , the overall thickness regulation is equally divided, the tightening force is equalized, and when the tatami face 9 is sewn, the back reinforcing plate 6 equalizes the sewing force on the back side, so the dimensional stability of the tatami is high. The tatami mat of the present invention is resistant to twisting, warping, etc. and has high durability, and if the back reinforcing plate 6 is not laminated, the entire tatami is easily bent and deformed such as twisting and warping. The effects of high dimensional stability and durability cannot be achieved. In particular, the front and back reinforcing plates 4 and 6 are made of rigid material with a thickness of 2 to 2.
By forming it to 5 mm, the effects of improving dimensional stability and durability can be achieved more reliably. in this case,
In order to improve the durability of the tatami mat surface 9, it is preferable to use a synthetic tatami surface made of polyvinyl chloride.
