PROBLEM TO BE SOLVED: To cut the unit floor material at the recess groove of the arbitrary position of a width adjusting part and adjust the width in response to the breadth of a laid place by integrally forming a decorative material attaching part and the width adjusting part juxtaposing a straight line-like recess groove at regular intervals on the surface of a rectangular floor plate. SOLUTION: A substantially square decorative attaching part 22 and a width adjusting part 2 are integrally formed on the surface of a planar view substantially square floor plate 1 comprising a thermoplastic synthetic resin. The decorative material attaching part 22 is divided into three substantially square recessed part by a partition wall 21, and locking pawls 23 are projected on the sides of the respective recessed parts. In addition, a plurality of straight line-like recess grooves 24 are juxtaposed on the width adjusting part 2 making the double width of the decorative material attaching part 22 at regular intervals along the longitudinal direction. A plurality of connection annuluses 3 are projected from the lower end of the two adjacent sides of the floor plate at regular intervals, and a locking projection 31 is projected on the upper end of the right and left inner walls of the connection annulus 3. Connection legs 4 are provided on the remaining two side walls of the floor plate 1 at regular intervals, and locking pawls 41 are provided on both sides on the lower end of the connection leg to fit the connection leg to the connection annulus 3 so as to form the floor plate 1.
