The bottom plate 45 of the screw covering portion 42 of the two reflecting plate 13 covers the lower part of the head 44 of the screw 12 as a whole.
Therefore, since the screw 12 including the head 44 is not directly viewed from below, the design can be improved.
In the screw covering portion 42, the bottom plate 45 contacts the head 44 of the screw 12.
Therefore, loosening of the screw 12 can be prevented.
At this time, even if the screw 12 is loosened, the screw covering portion 42 entirely covers the head portion 44 of the screw 12, so that the screw 12 can be prevented from dropping downward.

以上、説明したように第１実施形態の照明器具１０によれば、第２反射板１３が第１反射板１１側を小さくするように変形されて、爪部３１を第１反射板１１の係合部４０に係合させることにより、第２反射板１３のねじ被覆部４２がねじ１２を覆う。
従って、第１実施形態の照明器具１０によれば、ねじ１２が下方から直視されないために、意匠面で良好にできる。 As described above, according to the lighting fixture 10 of the first embodiment, the second reflector 13 is deformed so as to reduce the first reflector 11 side, and the claw portion 31 is engaged with the first reflector 11. By engaging with the joint portion 40, the screw covering portion 42 of the second reflecting plate 13 covers the screw 12.
Therefore, according to the lighting fixture 10 of 1st Embodiment, since the screw 12 is not directly seen from the downward direction, it can do favorably in a design surface.

また、第１実施形態の照明器具１０によれば、第２反射板１３のねじ被覆部４２の底板４５がねじ１２の頭部４４に当接するために、ねじ１２の緩みを防止できる。   Moreover, according to the lighting fixture 10 of 1st Embodiment, since the baseplate 45 of the screw coating part 42 of the 2nd reflecting plate 13 contact | abuts to the head 44 of the screw 12, loosening of the screw 12 can be prevented.

また、第１実施形態の照明器具１０によれば、第２反射板１３のねじ被覆部４２がねじ１２の頭部４４を全体的に覆うために、万が一に、ねじ１２に緩みが生じたとしても、ねじ１２の下方への落下を防止できる。   Moreover, according to the lighting fixture 10 of 1st Embodiment, since the screw coating | coated part 42 of the 2nd reflecting plate 13 entirely covers the head 44 of the screw 12, it assumes that the screw | thread 12 loosened by any chance. In addition, the screw 12 can be prevented from dropping downward.
