A connecting screw 46 is screwed into the screw hole 45 of 4 in advance. The screw 46 is provided so as to have a gap between its head and the inner surface of the arm plate 44. Thereafter, the arm end portions 44 of the pair of frame end plates 41 are respectively placed on the horizontal portions 21a of the ceiling plate support bars 21, so that the frame end plates 41 are respectively positioned between the pair of ceiling plate support bars 21. Erect. At this time, the width between the pair of ceiling plate support bars 21 slightly varies with respect to the set dimensions according to the variation in the hanging positions of the support bars 21. However, since the frame end plate 41 is made of sheet metal and has a configuration in which the pair of arm plate portions 44 are bent with respect to the end plate portion 43, the bent portions forming these boundaries are centered, By moving the pair of arm plate portions 44 in a direction of increasing or decreasing the distance between the pair of arm plate portions 44, the pair of ceiling plate support bars 21 that vary the distance between the pair of arm plate portions 44 is varied. Can be adapted to the width between. In this way, the margin of the frame end plate 41 to the ceiling plate support bar 21 can be ensured, so that the frame 31 is moved from between the ceiling plate support bars 21 due to the variation in the width between the pair of ceiling plate support bars 21. The risk of falling off can be eliminated.

１が脱落することもない。The light control body 33 is not directly attached to the pair of ceiling plate support bars 21, but the light control body 33 is attached to these bars 21 via the frame body 31. Since it is provided mounted on the pair of ceiling plate support bars 21, it is less affected by the variation in the width between the pair of ceiling plate support bars 21. Thus, the frame 31
The shape of the pair of frame side plates 42 is not largely changed.
Since the interval between them can be kept substantially constant, the mounting of the light control body 33 does not occur. In addition, for the same reason, even when the width between the pair of ceiling plate support bars 21 is wider than the set dimension, the frame body 31 can reliably support the light control body 33. There is no danger of the 33 dropping out carelessly. Of course, as described above, the frame 31 is placed so as to be adapted to the width of the pair of ceiling plate support bars 21 by adjusting the interval between the arm plate portions 44.
No one will fall off.

下する恐れがないように取付けることができる。As described above in detail, in the light control device for a lighting device for a system ceiling according to the present invention, after a frame end plate is placed between a pair of ceiling plate support bars, these frame end plates are connected by a frame side plate. Since the frame is assembled by connecting the frame and the light control body is attached to the frame, the light control body can be supported by the frame which is less affected by the positional accuracy of the pair of ceiling plate support bars. Irrespective of the variation in the interval between the plate support bars, the mounting of the light control body does not occur. The light control body is attached to the frame body by detachably engaging the first and second engaging portions of the light control body with the mounting holes of the frame side plate, and using a leaf spring as in the prior art. It is not possible to attach and detach the light control body while elastically deforming it, so that the workability of attaching and detaching the light control body between the pair of ceiling plate support bars can be improved. In addition, since the distance between the pair of arm plate portions of the frame end plate can be adjusted, and the margin of the frame end plate with respect to the ceiling plate support bar can be sufficiently secured, the distance between the pair of ceiling plate support bars can be reduced. And the light control body can be mounted without fear of falling.
