  Furthermore, the leg body 21 can be rotated in the surface direction of the lower surface 13a of the plate body 13 even after the plate body side metal fitting 32 and the leg body side metal fitting 42 are connected. Therefore, as in the first embodiment described above, as shown in FIG. 7, when the leg 21 is a square leg or the like, the angle of the square leg 21 with respect to the corner of the plate 13 when the square leg 21 is attached. Even if there is a deviation, such a deviation can be eliminated by finely adjusting the square leg 21 in the rotational direction.

  Moreover, by providing the unevenness 43a on the side peripheral surface of the head 43, the rotation of the head 43 when the plate-side metal fitting 32 and the leg-side metal fitting 42 are connected can be suppressed by friction.

  Furthermore, in the plate-side metal fitting 32, the through hole 36 of the metal fitting main body 33 is provided at substantially the center of the main body portion 34, so that the attachment position of the leg 21 with respect to the plate-side metal fitting 32 becomes clear and the attachment work is easy. Become. In addition, since the through-hole 36 is substantially in the center of the main body 34, a sufficient area can be secured around the through-hole 36, so that a large number of screw holes 38 can be provided. Thereby, the plate body side metal fitting 32 attached to the attachment recessed part 14 can be firmly fixed to this recessed part 14.

  In the first and second embodiments described above, the through-holes 6 and 36 of the plate-side metal fittings 2 and 32 and the heads 16 and 43 of the leg-side metal fittings 15 fitted into the through-holes 6 and 36 are both substantially circular. However, for example, these may be rectangular to prevent rotation in the rotation direction. If configured in this way, the effect of fine adjustment of the rotational direction due to the circular formation of the through holes 6 and 36 and the heads 16 and 43 cannot be obtained. There is an advantage that can be prevented, which is contrary to the circular shape.

  In addition, by manufacturing furniture with legs such as a table or a chair using the first and second embodiments (attachments 1 and 31) described above, the furniture with legs has a small attachment 1 and 31. Since the number of points is low and it is inexpensive, the furniture as a whole is also inexpensive, and in addition to this, the attachment position of the legs 21 can be adjusted, so it is possible to suppress a decrease in yield as a product. It will be cheap.
