PROBLEM TO BE SOLVED: To provide a floor material capable of being partially and easily fitted in after construction.SOLUTION: In a floor material, a male tongue 10 comprising an upper vertical part 11, a protrusion 12 and a lower vertical part 13, and a female tongue 20 comprising an upper jaw part 21, a recess 22 and a lower jaw part 23 are provided at least in a transverse direction. The floor material prevents an upper corner part 23a of the lower jaw part 23 from being a hindrance to movement of the protrusion 12, when the male tongue of one floor material 30 is fitted into the female tongue of another floor material 40 by making a lower corner part 21a of the upper jaw part 21 of the female tongue in the floor material 40 rotated in the state of abutting on a top surface 12a of the protrusion 12 of the male tongue of the floor material 30 (see Fig. (b)). |
