PROBLEM TO BE SOLVED: To provide a floor board which can be removed to be reusable and can be fitted even when the floor board is made of a material other than wood. SOLUTION: A screw hole 2 is formed in a part where a protruding linear part 1A of the floor board 1 is formed. The screw hole 2 comprises a threaded part insertion part 2a for allowing a threaded part 3a of a screw 3 to be inserted and a screw head housing part 2b where a screw head 3b of the screw 3 is positioned in an embedded state. The threaded part 3a of the screw 3 is inserted into the threaded part insertion part 2a and screwed into a joist 4, whereby the floor board 1 is screw-cramped to the joist 4 in a state that the screw head 3b is positioned in the screw head housing part 2b. Then, a channel part 1B of an adjacent floor board 1 is fitted to the protruding linear part 1A and the next floor board is fixed to the joist in a similar manner as mentioned above. The screw 3 is embedded under a surface of the floor board by being fitted to the adjacent floor board so that it may not be seen from the floor surface. When the floor board 1 is removed, the opposite procedure is followed. COPYRIGHT: (C)2006,JPO&NCIPI
