PROBLEM TO BE SOLVED: To provide a small floor panel fixture having high strength while reducing the number of parts.SOLUTION: A floor panel fixture includes an upper plate made of steel, a lower plate fixed to the upper plate and opposed to a lower surface of the upper plate, and a nut disposed between the lower plate and the upper plate and to which a bolt is fastened. The upper plate has a concave portion in which a part of the lower surface is recessed larger than the outer shape of the nut, an engagement portion formed in the concave portion, a convex portion protruding from the upper surface at a position corresponding to the concave portion, and a through hole penetrating the convex portion and the concave portion in the plate thickness direction of the upper plate and having an inner diameter larger than the inner diameter of the female screw of the nut. At least a part of the nut is accommodated in the concave portion, and the engagement portion blocks the rotation of the nut when fastening the bolt.SELECTED DRAWING: Figure 2
【課題】部品点数を少なくしつつ小型で強度の高い床パネル固定具を提供すること。【解決手段】床パネル固定具は、鋼製の上板と、上板に固定され上板の下面に対向する下板と、下板と上板との間に配置されると共にボルトが締結されるナットと、を備えている。上板は、下面の一部がナットの外形よりも大きく凹む凹部と、凹部に形成された係合部と、凹部に対応する位置に上面から突出する凸部と、凸部および凹部を上板の板厚方向に貫通すると共にナットのめねじの内径よりも内径が大きい貫通孔と、を備えている。ナットは凹部に少なくとも一部が収容され、係合部はボルトの締結時にナットの回転を阻止する。【選択図】図２
