| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a floor material to prevent a gap and a play at a joint between a male tongue part and a female tongue part and reduce damage on a tongue part caused with factors such as a dimensional change or the like.SOLUTION: A lower surface 12b of a base end part 12 of a male tongue part 11 is inclined downwardly to a tip side, while a bottom surface 15a of an entrance part 15 of a female tongue part 14 is inclined upwardly to a tip side. An elastic member 20 is placed between an upper surface 13a of a tip part 13 of the male tongue part 11 and a ceiling surface 16b of a distal part 16 of the female tongue part 14.SELECTED DRAWING: Figure 1
【課題】雄実部と雌実部との接合部において目隙ができにくく、がたつきが起こりにくく、かつ寸法変化などを要因とした実部の破損が起こりにくい床材を提供する。【解決手段】雄実部１１は、基端部１２の下面１２ｂが先端側に向けて下り傾斜し、雌実部１４は、入り口部１５の底面１５ａが先端側に向けて上り傾斜しており、雄実部１１の先端部１３の上面１３ａと、雌実部１４の奥方部１６の天井面１６ｂとの間に弾性部材２０配される。【選択図】図１ |
