PURPOSE:To interrupt electric conduction through a grounded steel frame or reinforcement on the body side of a ceiling backing material by simple structure while preventing the display of an antenna function of ceiling hanging hook itself. CONSTITUTION:A hanging hook 12 hanging a ceiling backing material is divided in the vertical direction, and a first hanger rod 20 in an upper section and a second hanger rod 22 in a lower section are bonded through a short columnar- shaped insulator 24. The first hanger rod 20 is inserted and mounted into a mounting hole 24a formed at the central section of the insulator 24. The second hanger rod 22 is installed to an annular groove 24b formed on the outside of the insulator 24 through a fixture 32. |
