<p>PROBLEM TO BE SOLVED: To eliminate working for removal of a pressing member when a ceiling member is fixed or removed, facilitate an accommodation of the pressing member corresponding to a plate thickness of the ceiling member and improve a fixing or removing characteristic of the ceiling member by a method wherein the pressing member is slid at an upper surface of the ceiling member from the inside of a frame member. SOLUTION: A suction grill fixed to an opening of an ornamental panel is comprised of a frame member 12 forming an outer shell, and a ceiling member 13 fixed to the frame member 12. Both right and left side edges 12c of the frame member 12 are provided with pressing members 31 for pressing the ceiling member 13 from above. The pressing member 31 is arranged in such a way that it may be slidably set at a releasing position for storing it in a sectional plane of the frame member 12 when the ceiling member 13 is not fixed and a pressing position for drawing it out of inside of the frame member 12 and pressing the ceiling member 13 when the ceiling member 13 is fixed. The pressing member 31 is provided with a fixing means 40 for non-slidably fixing the pressing member 31 in respect to both side edges. The fixing means 40 is comprised of a longitudinal hole 33 extending in a sliding direction in the pressing member 31, and small screws 34 threadably fitted to both right and left side edges through the longitudinal hole 33.</p> |
