【実用新案登録請求の範囲】 ボルトは、 ねじ部と、 ねじ部の外径より最少寸法の大きい嵌合部と、 嵌合部の最少寸法以上の径の円柱状軸部とより
なり、 嵌合部は３または４面の平面部と、 曲面部とより形成し、 一方板体には嵌合部と同一形状の嵌合孔を開孔
して形成した、 ボルトと板体との嵌合構造。[Scope of claim for utility model registration] A bolt consists of a threaded part, a fitting part whose minimum dimension is larger than the outer diameter of the threaded part, and a cylindrical shaft part whose diameter is greater than the minimum dimension of the fitting part, and the bolt is fitted. The fitting structure between the bolt and the plate is formed by having a flat part with three or four sides and a curved part, and a fitting hole having the same shape as the fitting part in the plate. .
