PROBLEM TO BE SOLVED: To securely fix a connection hardware at a constant position on a gradient roof frame, and hold a ceiling suspension bolt in a perpendicular attitude. SOLUTION: Vertical plate parts 9, 13 of a first member 11 comprising a pair of parallel side plate parts 10, 10 perpendicularly protruded from both side end upper parts of the vertical plate part 9, and a second member 12 comprising a lower plate part 14 perpendicularly protruded from a lower end of the vertical plate part 13 are combined with each other in such a way that the side plate part 10 and the lower plate part 14 face each other vertically, and both are pivotally connected to each other to be mutually rotatable. A lock part 15 to a flange part 1a of a roof frame 1 is provided at a lower end part of the side plate part 10 of the first member 11, a ceiling suspension bolt thread hole 16 is provided in the lower plate part 14 of the second member 12, both side plate parts 10, 10 are locked on the flange part 1a, and an upper end of a ceiling suspension bolt 2 threaded with the screw hole 16 is pressed to a lower surface of the flange part 1a. |
