By using such a cover material, the positional relationship between adjacent floor panels can be easily adjusted. Moreover, by using the cover material made of synthetic resin, it is possible to exert a buffering effect and reduce walking noise on the floor panel.

  Further, the positioning protrusion formed on the cover material is protruded so as to enter a gap provided on the outside of the circumference of a circular opening formed by a corner portion of the adjacent floor panel. Abutting against the back side of the floor panel of the wall portion connecting the gap filling protrusion, the circular opening, and the flange portion formed in a step shape so as to accommodate the jaw portion formed in the upper portion of the panel fix. It is desirable to comprise a contact protrusion (Claim 3). By comprising in this way, while being able to determine the mounting position of a floor panel rapidly, the position shift of a floor panel can be prevented.

  Since the support leg of the floor panel of the present invention is configured as described above, the following effects can be expected.

  (1) By reducing the number of parts constituting the panel support legs, the management becomes easy and the cost can be reduced.

  (2) Since the loosening screw is screwed from above the cylindrical portion of the panel support member, the floor panel floor height can be prevented from slipping by an easy operation.

  (3) Attachment to the panel support can be facilitated by the locking claws provided on the cover material. Moreover, the positional relationship between adjacent floor panels can be easily adjusted by positioning protrusions provided on the panel placement surface of the cover material. Furthermore, by making the cover material made of synthetic resin, it is possible to exhibit a buffering effect and reduce walking noise on the floor panel.

  (4) By configuring the positioning projection formed on the cover material with the gap filling projection and the contact projection, positioning when the floor panel is placed on the support leg is facilitated. In addition, it is possible to reliably prevent the displacement of the floor panel after placement.
