Even when the positions of the lower end of the hanging bolt 16 and the inserting hole 26 of the receiving section 20 do not coincide and the lower end of the hanging bolt 16 passes away from the inserting hole 26 to a section lower than the place of the height of the inserting hole 26, the hanging bolt 16 is introduced from the opening 28 of the receiving section 20 to the inserting hole 26 of the receiving section 20, and no alignment is required. An engaging seat plate 34, into which the hanging bolt 16 is inserted, is held between the receiving section 20 and the nut 32, the engaging seat plate 34 is engaged with the receiving section 34 under the held state, and slipping-off from the opening 28 of the hanging bolt 16 is prevented by the engagement. |
