PURPOSE:To enable an opening of a ceiling plate to be formed without hanging an indoor device and to enable an installing work for the ceiling plate to be completed once. CONSTITUTION:A hanger element 1 for use in hanging an indoor device 30 is provided with indicating elements 7, 8 for indicating a position of an opening 28. The indicating element 8 is provided with a fixing member 16 for temporarily fixing pipes 14, 15 connected to the indoor device 30, resulting in that the pipes 14, 15 after performing a cutting action or a flaring work requiring a large working space can be temporarily fixed to the fixing member 16. In addition, since the indicating elements 7, 8 indicate a position of the opening 28, an installing operation for the ceiling plate 27 can be completely carried out once without hanging the indoor device 30 into a ceiling 36. |
