PURPOSE: To lessen the number of parts and of assembly process man-hours to reduce a cost, by constituting a luminair main body of a gutterlike top plate having a top panel, and of a pair of end plates which are engagedly fitted to the vicinity of both the end parts in the longitudinal direction of the top plate. CONSTITUTION: A part supporting surface 31, which is folded at nearly orthogonal to a flange surface 26, is made so as to face in a top plate 13 direction to position end plates 14 in the vicinities of the end parts in the longitudinal direction of the top plate 13. The edge surface 28 of the flange surface 26 is moved so as to be inscribed with the top panel 20 of the top plate 13 and the end parts of both side walls 21 and 21 to engage a claw part 29, provided on the edge surface 28, with a bag part 23, provided on the top board 13, to lock a locking hole 30 to a projection 24 provided on the top board 13. Moreover, tongue pieces 35 and 35, provided on the supporting surface 31, are engaged with tongue piece engaging parts 25 and 25 provided on both the side walls 21 and 21 of the top plate 13. Then the end plates 14 are jointed to both the end parts of the top plate 13, and then a lighting device such as a stabilizer 15 is fitted to attach a lamp socket 16 to an attaching part 34 to insert a control screw 18 into the hole of a reflecting plate 17, thereby fitting a lamp 19 to the socket exposed to a lower side from the reflecting plate 17. |
