The screw insertion hole 221 is for passing the shaft portion of the male screw member 25. Each screw insertion hole 221 is located inward from the inner end of the bottom wall 211 so as not to overlap the bottom wall 211 of the leg blade 21 in plan view.

  The upper plate 23 is a disk material having an outer diameter smaller than the outer periphery of the support column 1 by the thickness of the cover member 24 (upper wall 241), and is intermittently provided in the circumferential direction (six in the illustrated example). The screw insertion opening 231 is cut out. Similarly to the screw insertion hole 221 of the lower plate 22, the screw insertion opening 231 is for passing the shaft portion of the male screw member 25, and each overlaps with each screw insertion hole 221 in plan view.

  In order to fix the leg blade 21 to the column 1, the upper plate 23 is brought into contact with the lower end surface of the column 1, and the male screw member 25 is inserted from below into the screw insertion hole 221 and the screw insertion opening 231. What is necessary is just to be screwed together in the internal thread formed in the lower end part of 16.

  In the present embodiment, when the leg blades 21 are fixed to the support column 1, the floor space, which is a gap between the two specific leg blades 21, communicates directly with the wiring passage 14. For this purpose, the side wall 212 (on the side facing the gap) of the two leg blades 21 is refracted at the inner end portion to ensure the width of the gap, and the upper plate 23 is provided with the two leg blades 21. A wiring opening 232 is cut out along the side wall 212. The outer edge of the wiring opening 232 overlaps the opening 15 of the outer wall 13 of the pillar 1 in plan view, and the opening width is substantially equal to the opening width of the outer wall 13 of the pillar 1. As a result, the space above the floor between the two leg blades 21 continues to the wiring passage 14 via the wiring opening 232. The floor space, the wiring opening 232 and the wiring passage 14 are consistently opened to the side of the furniture.

  The cover member 24 as a whole surrounds the outer periphery of the support column 1 over substantially the entire periphery, shields the floor around the support column 1, and is detachable from the leg blade 21.
