PROBLEM TO BE SOLVED: To provide an installation metal fitting for a metal roof with which an installed object is fitted by screwing a holding nut and a fitting nut on a common bolt, the installation metal fitting enabling the installed object to be fixed with sufficient fitting strength.SOLUTION: By tightening a fixing nut 108 on a male screw 104 of a holding nut 80, the holding nut 80 is held rotatably on a base member 30 in a way that disables a relative motion in an axial direction. A bolt 48 screwed in the holding nut 80 is disabled from moving up and down relative to a support bracket 20, while the support bracket 20 is fixed on a metal roof model 14 by tightening the holding nut 80. A tensile member 82 is divided into two members, namely a first tensile member 82a and a second tensile member 82b, and the first tensile member 82a and the second tensile member 82b respectively have a connecting plane part 84 disposed on an opposite side of an engaging part 96. When the bolt 48 completes an upward motion, the connecting plane part 84 of the first tensile member 82a and the connecting plane part 84 of the second tensile member 82b are overlapped surface-to-surface.SELECTED DRAWING: Figure 3 |
