PROBLEM TO BE SOLVED: To improve brightness in a side plate direction and a ceiling direction in a long lighting fixture.SOLUTION: In a cover portion 230, a lower supporting portion 234 (extension portion) extended toward a mating (right side of central shaft 11) lower side wall shape portion 2233-2 is formed from a terminal end portion in a Z direction, of a left lower side wall shape portion 2233-2 of the central shaft 11, and a lower supporting portion 234 is formed also at a right side of the central shaft 11. A member connected to an opposite face opposed to the mating cover side wall portion 232 does not exist on the cover side wall portion 232. That is, a space 238 exists between the lower supporting portion 234 and the opposite face of the cover side wall portion 232. On the lower supporting portion 234, a reverse direction extension portion extended in a direction to be connected to the cover side wall portion 232, such that shown by a two-dot chain line, does not exist.SELECTED DRAWING: Figure 9 |
