Abstract

PURPOSE: To surely and firmly attach an illumination cover to a luminaire main body without playing, by regulating both side locking pieces to both side fitting holes without play at external side, and elastically locking spring pieces to the inner side hole edges of the fitting holes. CONSTITUTION: In an illumination cover fitting device, locking pieces 4 on both upper and lower sides are regulated without play to fitting holes 2 on both upper and lower sides respectively at external side, by making the outer end edges of rising pieces 10 abut on the outer side hole edges of the holes 2. Moreover, spring pieces 5 are elastically locked to the inner side hole edges of the holes 2 to prevent the falling-out of the pieces 4 and also the playing movement. Since, inner side spring pieces 5, not projection pieces 44 which is adopted as the main body of the pieces 4, are elastically deformed, and the pieces 44 have thick thickness and are firmly formed; the illumination cover 3 can be surely and firmly attached without playing. Moreover, since beveling taper-like taper parts 6 are provided on the tip outer edge portions of the locking metallic fittings 7 of the pieces 4, they can be regulated to the holes 2 without play at external side, and also, the locking pieces together with the fittings 7 can be smoothly inserted in the holes 2.
