Panel hinges 60, each of which constitutes a hinge part with a hook 63 having a locking claw 62 provided in projection to the front end thereof, are fixed to one side of a ceiling panel 10A installed on the swing side. The hook 63 of the panel hinge 60 fixed to the ceiling panel 10A on the swing side is fitted into a locking slit 15b, provided to the side wall of a ceiling panel 10B on the fixed side installed adjacently in the rectangular space 3, so that the ceiling panel 10A becomes swingable, and the side of the ceiling panel 10B facing the side of the swing-side ceiling panel 10A, to which the panel hinge 60 is fixed, is held detachably in a locking groove 4c of the ceiling finishing material 4. |
