PROBLEM TO BE SOLVED: To prevent so-called a mirrored phenomenon that a stop retainer to prevent a cover from dropping makes a shadow on the cover during use. SOLUTION: A stop retainer 11 and a stopper 15 are provided on the luminaire body 1 side and the cover 2 side respectively, a structure to prevent the cover 2 from dropping is formed by them, and an operating part 13 is provided in the retainer 11. When the cover is mounted, the retainer 11 is rolled inward from a stop position to a retracted position by pushing the operating part 13 with the stopper 15, and is kept there so as not to drop long in the cover 2 by holding it at this position. |
