And the main body holding portion 2 having a substantially circular shape in plan view at the center of the buffer 1 is recessed downward from the upper edge of the buffer 1 at the center side. The main body 3 of the lighting fixture is formed by the main body holding portion 2.
(Substantially circular shape in plan view), and the lower edge of the shade 5 is placed on the step 4 outside the base of the buffer 1. The plurality of convex portions 6 formed at predetermined intervals on the buffer 1 and retreated from the step 4 above the step 4 are formed in a substantially circular outer shape in plan view and extending outward and downward from the upper edge of the buffer 1. Between the part 7 and the step part 4, it protrudes outward, and the inner edge 8 of the lower edge of the shade 5 is positioned outside the convex part 6. These are stored in the packaging box 9. Note that the step portion 4 in this paragraph is a concept including a substantially planar step portion, that is, a substantially flat portion. The raw material of the buffer 1 is preferably a material obtained by appropriately mixing waste paper pulp with a synthetic resin such as polyethylene.

More specifically, the shock absorber 1 has a substantially flat portion 10 extending outside the base of the step portion 4, and the tip of each corner portion of the substantially flat portion 10 is chamfered to be substantially planar. Form a square shape. The convex portion 6 is located at each corner of the buffer 1, and the lower edge of the shade 5 having a substantially square shape in plan view is located at each corner of the step 4 having a substantially square shape in plan view. It is placed on the part that does. Each of the chamfered portions 11 is provided on each side plate 12 of the packaging box 9 having a substantially square shape in plan view.
