A male screw portion 7a is provided only at a predetermined section at the upper end of the height adjusting screw 7.
The lower portion of the male screw portion 7a is a small diameter portion 7b only in a predetermined section, and the lower portion of the small diameter portion 7b is a straight portion 7c without a screw. A head 7d is provided at the lower end of the height adjusting screw 7, and a washer 7e is provided on the head 7d. Elastic cylindrical body 8 formed of an elastic body
Is inserted through the outer periphery of the shaft of the height adjusting screw 7, and a nut 9 is built in a predetermined section in the elastic cylindrical body 8.
The nut portion 9 is screwed into the male screw portion 7a, but idles with the small diameter portion 7b.

[0007] The ceiling panel 1 is suspended and supported on the upper floor component by the ceiling suspender A. The upper floor component is the floor panel 10 in this example, as shown in FIG. It is formed by attaching a face plate 10b to a frame material 10a such as a mold steel, and a flange below the frame material 10a is a protruding piece 11. The ceiling panel 1 has a crosspiece 1b around the upper surface of the face plate 1a.
Are formed integrally with each other, and an insertion hole 12 penetrating vertically through the ceiling panel 1 is formed in the portion of the crosspiece 1b. The insertion hole 12 includes an upper insertion hole 12a having substantially the same diameter as the outer diameter of the elastic cylinder 7 and a lower insertion hole 12b having a diameter sufficiently larger than the outer diameter of the elastic cylinder 2.
A step 12c is provided between the lower hole 2a and the lower insertion hole 12b.

[0008] When the ceiling panel 1 is suspended and supported by the ceiling suspension A, the following procedure is performed. Fig. 4 (a)
The height adjusting screw 7 having the elastic cylindrical body 8 attached to the outer periphery of the shaft portion is inserted into the insertion hole 12 from below the ceiling panel 1 as described above, and the head 7d at the lower end of the height adjusting screw 7 is inserted into a tool such as a screwdriver. To rotate the height adjustment screw 7.
