PURPOSE:To prevent production of a gap between an apparatus main body and an end part in spite of dispersion in mutual intervals between ceiling support bars by composing at least one of a pair of end plates installed at the apparatus main body to slide freely along the length of the apparatus main body. CONSTITUTION:An end plate 26 to be mounted on a horizontal member 15 of a ceiling support bar 13 is installed to slide freely along the length of a main body 21 at each end part of the length of the apparatus main body 21 where a fluorescent lamp 23 is incorporated. A hooking means 33 is fixed on an outer surface of the end plate to be hooked at a support wall 16 of the bar 13, and the end plate 26 is connected with the main body 21 at a desired slide position by a screw 32 through a slit 31 provided at the end plate 26. An interval between the end plates 26 can thus be adjusted corresponding to an interval between the bars 13, thereby a gap between the main body 21 and the end plate 26 can be eliminated. |
