Further, when the support tool 6 is screwed into the grill frame 4A, the tip of the support tool 6 is communicated with the support tool mounting hole 7 of the grill frame 4A from the outside, and the length of the L-shaped notch 12 and the holding piece 17 of the inner lid 5 is communicated. The round hole 16 or the L-shaped notch 10 or the long round hole 11 is penetrated.
[0019]
With the above configuration, the inner lid 5 does not fall off the grill frame 4A due to careless operation, and the holder 14A can be easily and freely attached from the inside of the grill frame 4A by opening the inner lid 5 downward. Since the L-shaped notch 12 on the fulcrum side of the inner lid 5 has no protrusion by removing the holder 14A and the holding piece 17, the L-shaped notch 12 without the protrusion The inner lid 5 can be easily and quickly attached and detached without removing the support 6 that is usually outside and hidden in the ceiling.
[0020]
(Example 3)
As shown in FIGS. 8 and 9, a holding piece mounting hole 21 is provided at the fulcrum side end of the U-shaped bent portion of the longitudinal direction of the panel, and a holding piece mounting hole 18 </ b> A communicating with the holding piece mounting hole 21 is provided. The A-shaped holding piece 17A is provided, and the holding piece mounting hole 18A and the holding piece mounting hole 21 are screwed into each other by the holding tool 14B.
[0021]
With the above configuration, the inner lid 5A does not fall off the grill frame 4A due to careless operation, and the holder 14B comes to the front position by opening the inner lid 5A downward. Can be easily attached and detached from the grille frame 4A, and the L-shaped notch 12 on the fulcrum side of the inner lid has no protrusion by removing the holder 14B and the holding piece 17A. The inner lid 5A can be easily attached and detached by the notch 12, and it is not necessary to remove the support 6 that is usually outside and hidden in the ceiling.
[0022]
In order to facilitate the work on the holding piece 17A, a round hole of a size that allows a finger to enter or a notch portion into which the effective thread of the support 6 can be inserted may be provided on one side surface. It goes without saying that the shape is not limited to this shape as long as the action and effect are obtained.
[0023]
【The invention's effect】
As is clear from the above embodiment, according to the present invention, the holder can be removed from the inside of the grill frame by opening the rotating inner lid downward, and the L-shaped cut-off is provided on one side of the inner lid on the fulcrum side. By providing the notch portion, the inner lid can be easily attached and detached easily by avoiding the support screwed from the outside of the grill.
