The supporter body 32 is slid in the longitudinal direction of a main body 14 of the luminaire while a chassis 15 of the main body 14 of the luminaire is guided by the edge of a notch 38 of a slide portion 33 and while avoiding suspension bolts, duct, etc. The screws 50 are again fastened to fix the supporter body 32. A lower end of each supporting leg portion 34 of the supporter body 32 is placed on the upper end of a ceiling frame, an elastic piece portion 49 is engaged with a side face of the ceiling frame, and the main body 14 of the illumination device 14 is supported on the ceiling frame via the supporter body 32, In the case where a light controller is fitted to a lower portion of the main body 14 of the luminaire, the supporting leg portion 34 of the supporter body 32 is moved downward relative to a retaining plate portion 36. By an engaging piece portion 41 fitted to the retaining plate portion 36, the supporting leg portion 34 is again fixed by engagement.
