At that time, the position of the fixing hole 25 formed in the side plate 21 of the instrument main body 2 and the position of the mounting hole 64 formed in the member fixing portion 61 of the mounting member 6 coincide with each other.

After that, as shown in FIG. 9, the contractor inserts the fastening member 70 into the fixing hole 25 and the mounting hole 64 and screwes them together. As a result, the mounting member 6 is fixed to the instrument body 2. Finally, the contractor lowers the appliance main body 2 to which the mounting member 6 is fixed vertically toward the living room side. At this time, the member claw portion 65 of the mounting member 6 is caught by the tip portion 7b of the support member 7. As a result, the luminaire 1 is attached to the system ceiling 9.

According to the first embodiment, the mounting member 6 is provided with a second opening 63 that guides the claw portion 24 inserted into the first opening 62 to slide and holds the slid claw portion 24. Is formed. Therefore, the contractor can lift the appliance main body 2 while keeping it vertical, insert it into the space behind the ceiling, and then immediately attach the attachment member 6 to the appliance main body 2 without using screws or the like. Therefore, the mounting member 6 does not fall from the hand, and it is not necessary to maintain the state in which the accommodating frame is lifted. Therefore, the lighting fixture 1 can suppress adverse effects on the construction work.

Further, the claw portion 24 has a projecting portion 24a protruding from the side plate 21 and a pressing portion 24b connected to the projecting portion 24a and extending downward from the projecting portion 24a to press the mounting member 6. Therefore, when the claw portion 24 inserted into the first opening 62 slides and is held by the second opening 63, the member fixing portion 61 of the mounting member 6 is formed by the instrument main body 2 and the pressing portion 24b. Is sandwiched. Therefore, it is possible to prevent the mounting member 6 from separating from the instrument body 2 in the normal direction of the side plate 21 of the instrument body 2.

Further, the lower end of the second opening 63 extends laterally from the upper end of the first opening 62. That is, a step is formed at the boundary between the first opening 62 and the second opening 63. Therefore, when the claw portion 24 inserted into the first opening 62 slides and is held by the second opening 63, the claw portion 24 moves from the second opening 63 to the first opening 62. It is possible to suppress the return. From the above, the mounting member 6 is hard to come off from the instrument main body 2 even if it is not fixed by screws or the like.

Then, after the lighting fixture 1 is attached to the system ceiling 9, the claw portion 24 of the side plate 21 of the fixture main body 2 is supported by the edge portion of the second opening 63. That is, the edge of the second opening 63 of the mounting member 6 supports the load of the luminaire 1. In this way, when the load of the luminaire 1 is applied to the luminaire 6, the luminaire 6 is pressed downward against the luminaire 1. Therefore, even if the mounting member 6 is not fixed to the instrument body 2 with screws or the like, it is possible to prevent the mounting member 6 from coming off the instrument body 2.
