For example, as shown in FIG.
The engaging parts 19a to 19d of the wooden frame assembly pillar material 5 are engaged with the notches 1g to 4g formed on the side edges of the frame a. As a result, the notch portion 1g and the engaging portion 19a of the uppermost plate 1a engage with each other, and the wooden frame gripping piece 1
It is supported by being gripped by 7.
In addition, the lowest plate material 4a has a cutout portion 4g and an engaging portion 1.
9d, and is supported by being gripped from below by the wooden frame gripping pieces 18. Also,
The middle plates 2a and 3a each have a notch 2g.
It is supported by the engagement between the engaging portion 19b and the notch 3g and the engaging portion 19c. Similarly, plate material 1
The four engaging portions of the wooden frame assembly pillar material 6 engage with the notch portions arranged in parallel with the notch portions 1g to 4g of a to 4a, respectively, to support the plate materials 1a to 4a. Furthermore, in the same way, the remaining three sides of each wooden frame are made up of a pair of wooden frame assembly pillars 7, 8, and 9.
and 10, 11 and 12. Through such assembly, a shade is obtained in which four wooden frames combined in a protruding shape are integrally supported by eight wooden frame assembly pillars as shown in FIG.

Other accessories of the lighting fixture are attached to the shade in the above assembled state. As shown in FIG. 3, the globe 20 is inserted into the wooden frames assembled in four stages, and the upper edge of the globe 20 is supported by the globe supporting portions of the respective wooden frame assembly pillars 5 to 12. for example,
The upper edge 20a of the globe 20 includes the globe support portion 13 of the wooden frame assembly column 5, the globe support portion 14 of the wooden frame assembly column 6, and the globe support portion 1 of the wooden frame assembly column 7.
