PROBLEM TO BE SOLVED: To prevent a light transmission plate from crushing a tubular lamp through the falling impact or the like of the plate, even if it may be large-sized, by arranging a plate-supporting member between the plate and proximity to the tube of the light source. SOLUTION: A pair of ears 34 are provided projectingly in a lower part on both sides of a rectangular light transmission plate 22, and stored in a frame 20. Then, a space 36 for storing a tubular lamp 24 is provided between one projecting side of the ears 34 and the frame 20. A cushioning member 26 is each attached to over the lead wire 38 projecting from both ends of the tubular lamp 24. The lead wire 38 is for supplying electric power to the tubular lamp 24. The cushioning member 26 is such that a rubber-like elastic member 40 is wrapped by a metallic plate 42. The elastic member 40 is provided in its center with a through-opening for the lead wire 38 to go through. The tubular lamp 24 is stored in the storage space 36 after the cushioning member 26 is attached to the lead wire 38 projecting from both ends of the tubular lamp 24.
