Further, in order to prevent squeak noise caused by expansion and contraction of the cover between the cover frame and the cover, the cover receiving portion of the cover frame is flattened to make the cover slippery. Therefore, the cover frame
The space between the covers is closed, and the degree of airtightness between the top and the bottom of the cover may be high due to the high degree of sealing inside the upper device. In particular, when the air pressure inside the device above the cover is high, the cover may be unexpectedly dropped.

の経路と並列になるためである。DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will be given with reference to FIGS. 1 and 2 according to the present invention has a local ventilation gap 2 a between the cover frame 2 and the cover 3. 1 is an instrument body, 1a is a ventilation hole, 4 is a V spring, 5 is a fluorescent lamp, 6 is a reflection plate, 7 is a spacer, 8 is a flow of air, 9 is a ceiling material, and 10 is a light shielding packing. Arrow 8 is the air flow. The cover 3 is translucent and is held by the cover frame 2. The cover frame 2 is supported by an unremovable and compassionate V-spring with respect to a receiving metal fitting (not shown) of the instrument body 1. Cover frame 2
-A spacer 7 is interposed between the covers 3. Also, a portion not locally interposed is formed. The location is the ventilation gap 2
a. There is a ventilation hole 1a in the upper part of the appliance body 1, through which the interior of the appliance body 1 communicates with the inside of the ceiling (the space outside the appliance body 1 above the ceiling material 9). The upper and lower sides of the reflector 6 in the apparatus main body 1 communicate with each other via gaps on both sides of the reflector 6.
For this reason, a series of air flows 8 passing through the ventilation gap 2a
Is formed. The air flow 8 plays the role of heat dissipation. As described above, when there is no ventilation gap 2a, a pressure difference is generated between the upper and lower sides of the cover 3, and the cover frame 2 and the cover 3 drop against the V spring 4 particularly when the lower side has a negative pressure. Sometimes. The ventilation gap 2a prevents such a fall. Fig. 3.
Another embodiment of FIG. 4 will be described. 10 is a cover frame 2
This is a packing that enhances the adhesion between the ceiling material 9 and the ceiling material 9 and prevents light leakage. In this case, the cover frame 2 and the ceiling material 9 ventilation gap 2a '
To form This is formed by cutting out a part of the spacer 7 ′ interposed therebetween or cutting out a part of the cover frame 2. The purpose is almost the same as above, and the pressure difference generated on the upper and lower sides of the ceiling material 9 is eliminated. In this case, the ventilation gap 2a in FIGS. 1 and 2 can be omitted. Figures 1 and 2
If there is a similar ventilation hole 1a, the path of 1a-2a 'is 2a.
This is because it becomes parallel with the route of FIG.
