PURPOSE:To install a discharging port of a line diffuser so as to coincide with an air flowing port without loading the weight of the line diffuser on a ceiling facility panel by a method wherein the discharging port of the line diffuser is abutted against a box type ceiling facility panel, having an air flowing port and hung by a ceiling joint bar, so as to surround the air flowing port. CONSTITUTION:A ceiling facility panel 3 is formed so as to have a box shape equipped with a bottom wall horizontally, while the bottom wall is provided with an air flow port 32 and a hanging frame is provided on the upper part of side walls whereby the ceiling facility panel 3 is hung by a ceiling joint bar 1. A line diffuser 5 is provided with the same width as that of the air flow port 32 of the ceiling facility panel 3, while the lower surface thereof is provided with a discharging port 53, whose sectional configuration is provided with a size enough to surround the air flow port 32. The discharging port 53 of the line diffuser 5 is abutted against the air flow port 32 so as to surround the air flow port 32 while regulating the position of the line diffuser 5 so as to be positioned at a desired position with respect to the air flow port 32, opened on the ceiling facility panel 3. |
