Abstract
Disclosed herein is an improved floor board. The floor board includes a side female fitting part having a recess, an end male fitting part and an end female fitting part allowing snap coupling, and a foam hot-melt adhesive having superior restoring capability, thus overcoming problems of a conventional floor board. That is, this invention prevents height differences from being formed between floor boards due to the unevenness of a floor, when the floor boards are assembled in a length direction thereof, and prevents the floor boards from becoming deformed or damaged, during widthwise slanted coupling. Further, this invention minimizes noise transmitted between layers of the floor boards.
