PURPOSE:To facilitate an operation of fitting to an anchor bolt in the ceiling by a method wherein a temporal fixing part made of metal and projecting into a through hole is provided for a suspension metal fitting so that the inside diameter thereof is smaller than the outside diameter of the anchor bolt. CONSTITUTION:On the occasion when a main body is fitted to an anchor bolt 17, an upper nut 20 is screwed on the anchor bolt 17 beforehand and a suspension metal fitting 19 is put on the anchor bolt 17 from below through a through hole 19a. Since the width M in the lateral direction of a through hole 22a of a temporal fixing member 22 projecting into the through hole 19a of the suspension metal fitting 19 is smaller than the outside diameter D of the anchor bolt 17, an operator presses in, so to speak, the temporal fixing member 22 by a strong force, on the occasion, so that the member be made to get over the thread of a male screw part 18. Thereby the suspension metal fitting 19 is held in a state of being fixed temporarily to the anchor bolt 17. Thereafter the suspension metal fitting 19 is held tightly between the upper nut 2 and a lower nut 21 and thereby fitting of the main body to the anchor bolt 17 is completed. |
