After adjusting the condition, the screws shown in FIGS. 7 and 8 must be tightened with the horizontal screws 14 and 15 so that the screwing condition is not loosened by vibration of the floor surface or the like. Also, in the apparatus shown in FIGS. 10 and 10, there is a problem that the tightening operation of the horizontal screw 17 must be performed, and this tightening operation is troublesome.

[0007] The above-mentioned conventional floor panel support leg is
When the tightening of the horizontal screws 14, 15 and the horizontal screws 17 is loosened due to vibration of the floor surface or the like, play between the nut 12 or the long nut 16 and the screw portion 13a of the support leg 13 causes the support leg 13 to be loosened. There was a problem that the panel support 10 attached on the upper side was shaky.

Accordingly, the present invention is to solve the above-mentioned conventional problems, and eliminates the need for a screw to cut a horizontal screw by removing the horizontal screw.
The object of the present invention is to provide a floor panel supporting leg which does not require a troublesome tightening operation and which does not rattle even if there is no lateral screw.

[0009]

Therefore, the floor panel support leg of the present invention has an insertion hole 3a, and a screw hole 3b which is offset from the center of the insertion hole 3a below the insertion hole 3a. The long nut 3 is fixed to the lower surface of the panel support 1, and the screw portion 2 a provided on the support leg 2 is screwed into the screw hole 3 b of the long nut 3, and the support leg is inserted into the insertion hole 3 a of the long nut 3. 2 when the screw 2a of the support leg 2 is inserted.
At least a part of the side peripheral surface of the nut is an insertion hole 3a of the long nut 3.
The panel support 1 is mounted on the support leg 2 so as to contact the inner wall w of the panel.
