PROBLEM TO BE SOLVED: To use a ceiling suction port also as an inspection door. SOLUTION: A prismatic frame-like case 6, extending from an opening la bored on the ceiling 1 toward the space on the rear side of the ceiling, is fixed to the rear side of the ceiling with a fixing member 7, and a cover 10 is journaled to one side of the upper end 6a of the frame-like case 6. The angle of inclination of the cover 10 can be changed by an expanding/contracting mechanism 11. A lattice body 8 is attached to the lower part of the frame-like case 6 by an attaching/detaching device 9. At the time of air conditioning, the cover 10 is inclined to guide the indoor air in the direction of the arrow A. At the time of inspection, the attaching/detaching device 9 is detached to remove the lattice body 8, and the expanding/contracting mechanism 11 is expanded to full open the cover 10 so that an inspector goes in/out of the opening. |
