FLOOR MATERIAL

PROBLEM TO BE SOLVED: To provide a floor material having a fitting shape in which a gap in a joint part between floor materials is hardly conspicuous when the floor material is fitted and subjected to the influence of humidity and temperature and shrank, and having the fitting shape hardly causing the disengagement and hardly causing the rise and step difference in level.SOLUTION: A floor material includes: a linear engaging recessed groove part 223 having a back surface side cut off is provided at one end of the substantially rectangular planar member; a tip of the one end part is provided with a first projection part 221 in which a front surface side is obliquely cut off; a linear engaging recessed groove part 234 fitted with the linear engaging recessed groove part 223 from which the surface side of the opposing other end part is cut off; a fitting structure provided with a second projection part 231 whose lower side is obliquely cut so as to be joined to the first projection part 221 at a tip of one end part on an inner surface of the engaging recessed groove part 234.SELECTED DRAWING: Figure 4 【課題】嵌合して敷設し湿度、温度の影響を受け、収縮した際に床材同士の目地部における隙間が目立ち難く、また嵌合が外れ難く突上げや段差の発生のし難い嵌合形状を有する床材を提供する。【解決手段】略矩形平面部材の相対する一方の端部に、裏面側が切除された線状の係合凹溝部２２３を備え、上記一方の端部の先端は表面側が斜めに切除された第１突起部２２１を備え、相対する他方の端部の表面側が切除された線状の係合凹溝部２２３と嵌合する線状の係合凹溝部２３４を備え、上記係合凹溝部２３４の内面に上記一方の端部の先端の第１突起部２２１と接合するように下側が斜めに切除された第２突起部２３１を備えてなる嵌合構造を有する床材である。【選択図】図４
