PROBLEM TO BE SOLVED: To contrive the reduction of weight, number of parts and cost while securing rigidity by a method wherein an inside rod member and an outside rod member are formed of synthetic resin so as to have a hollow shape, in a decorative panel, arranged in parallel to the outside of the inside rod member and provided with the outside rod member, forming an air outlet port between the inside rod member. SOLUTION: Decorative panels 2 for a ceiling embedded type air conditioner are arranged in parallel to each other and are provided with a pair of inside rod members 3a, forming an air suction port A between each other, a pair of outside rod members 4a, arranged in parallel to the outside of the inside rod members 3a and forming air outlet ports B between the inside rod members 3a respectively, a pair of connecting members 5, connecting both of the rod members 3a, 4a mutually at both end units thereof, airflow direction changing vanes 6 and the like. In this case, both of the rod members 3a, 4a are formed of synthetic resin so as to have a closed hollow section to secure rigidity by themselves. In this case, both of the rod members 3a, 4a can be constituted of expandable synthetic resin so as to have a solid section to secure the rigidity and heat insulating property. |
