Things are known. Here, the top plate side metal fitting is attached to the lower surface of the table top plate, and the square head of the leg side metal fitting attached to the table leg is fitted into the square mounting hole formed in the top plate side metal fitting. A fixing screw is screwed into a screw hole that obliquely penetrates the mounting hole, and the tip of the fixing screw is brought into contact with the first locking slope formed on the head to attach the leg-side metal fitting. It is configured to be supported and fixed in the hole.

Further, the mounting hole of the top plate side metal member has a second locking inclined surface formed on an upper portion of a wall surface facing the screw hole, and a fixing screw is screwed into the screw hole, When the head of the leg side fitting is pulled up by pushing up the first locking slope, the locking slope formed on the head causes
It rides on the locking inclined surface of (1) and exerts a retaining effect in the insertion direction of the head.

[0004]

However, in the above-mentioned conventional structure, since the head moves along the second inclined surface,
The leg side metal fittings slide laterally with respect to the top plate side metal fittings, and the amount of sliding also depends on the top plate side metal fitting installation error on the top plate, the leg side metal fitting installation error on the legs, and the fixing screw The difference in the feed amount causes a considerable difference.
For this reason, there is a drawback that the mounting positions of the legs on the top plate are not uniform.
