PURPOSE: To prevent the damage of a lighting apparatus body and a hanging tool, by lightening the shock by means of bearing portions even if external force is applied to a cover by connecting the lighting apparatus body to a mounting hole in the cover by means of shafts and the bearings.

CONSTITUTION: A lighting apparatus body 1 is hung down from the ceiling by means of a hanging tool 9, and a cover 2 divided into two partition bodies 5, 5 in a vertical plane is installed to the body 1 by means of a mounting in a vertical plane is installed to the body 1 by means of a mounting hole 3. In this case, shafts 7 installed to the body 1 in projecting hole 3. In this case, shafts 7 installed to the body 1 in projecting shapes are iserted into the hinge bearings 6 of the cover 2, and the partition bodies 5, 5 are mutually mounted in revolution-free forms. When something collides with the cover 2, only the cover 2 shakes at the shafts 7, and the shock is hardly applied to the lighting apparatus body 1 and the hanging tool 9, thus preventing the damage of these body and tool.
