At this time, the outer claw portion 51 engages with the distal end portion 12 of the support member 10.

  15, FIG. 16, FIG. 17, FIG. 18, FIG. 19 and FIG. 20 are perspective views showing the operation of the claw portion 5 in the first embodiment of the present invention. As shown in FIGS. 15 and 19, when the nail operation part 52 is pulled toward the instrument body 2, the outer nail part 51 is not pressed by the nail operation part 52, so that it does not elastically deform and the outer end plate part 46. The claw opening 47a is closed and engaged with the distal end portion 12 of the support member 10. For this reason, it is suppressed that the lighting fixture 1 remove | deviates from the supporting member 10. FIG. Also, as shown in FIGS. 16, 17, 18 and 20, when the nail operation part 52 slides outward in the longitudinal direction, the tip of the nail operation part 52 depresses the outer nail part 51 and The claw portion 51 is elastically deformed. Thereby, engagement with the outer claw part 51 and the front-end | tip part 12 of the supporting member 10 is cancelled | released. Therefore, an operator or the like can remove the lighting fixture 1 from the support member 10.

  FIG. 21 is a perspective view showing the side plate portion 3 according to Embodiment 1 of the present invention. Moreover, FIG. 22 is sectional drawing which shows the side-plate part 3 in Embodiment 1 of this invention. According to the first embodiment, the side plate portion 3 has the side plate main body 31 and the side plate side portion 32 extending along the extending portion 11 from the side edge portion of the side plate main body 31. And the front-end | tip part 12 of the supporting member 10 contacts the notch side 37a of the notch 37 formed in the side-plate side part 32. FIG. For example, when a load is applied from above the side plate side portion 32 by the ceiling panel 13 placed on the flange 33, a reaction force is generated from the front end portion 12 to the side plate side portion 32. In the first embodiment, as shown in FIG. 21 and FIG. 22, the side plate side portion 32 extending from the side plate main body 31 is in contact with the distal end portion 12 of the support member 10. Received in cross section 3. For this reason, the reaction force received from the front-end | tip part 12 can be disperse | distributed to the side plate side part 32 whole. Therefore, it can suppress that the lighting fixture 1 deform | transforms. Moreover, this Embodiment 1 has the effect that it can suppress that the mounting bracket etc. which are provided in the lighting fixture 1 remove | deviate, and can suppress that it deform | transforms.

  FIG. 23 is a perspective view showing the side plate portion 103 of the lighting fixture 100 in the comparative example. Moreover, FIG. 24 is sectional drawing which shows the side-plate part 103 of the lighting fixture 100 in a comparative example. As shown in FIGS. 23 and 24, there is conventionally known a lighting fixture 100 in which a side plate portion 103 is bent stepwise. The lighting fixture 100 according to the comparative example receives the reaction force from the distal end portion 12 on one surface of the side plate portion 103. For this reason, there exists a possibility that the side-plate part 103 may be distorted to the support member 10 side. On the other hand, in the first embodiment, as shown in FIGS. 21 and 22, the side plate side portion 32 extending from the side plate main body 31 is in contact with the tip portion 12 of the support member 10. Is received by the cross section of the side plate portion 3. For this reason, the reaction force received from the front-end | tip part 12 can be disperse | distributed to the side plate side part 32 whole. Therefore, it can suppress that the lighting fixture 1 deform | transforms.

  Further, the side plate side portion 32 is formed by being bent from the side edge portion in the width direction of the side plate main body 31. As described above, in the first embodiment, the case where the side plate main body 31 and the side plate side portion 32 are integrally formed is illustrated, but the side plate main body 31 and the side plate side portion 32 are formed as separate members. It may be.

  Further, the side plate side portion 32 further includes a projecting portion 36 provided outside the notch 37 and projecting along the extending portion 11 from the notch side 37a. Thereby, after the front-end | tip part 12 of the supporting member 10 contacts the notch side 37a, since it contacts the protrusion part 36 even if it tries to move to a horizontal direction, it can suppress that the front-end | tip part 12 remove | deviates.

  The end plate portion 4 includes an inner end plate portion 41 disposed on the instrument body 2 side, and an outer end plate portion 46 disposed outside the inner end plate portion 41 and attached to the inner end plate portion 41. The notch 37 is located between the inner end plate portion 41 and the outer end plate portion 46. For this reason, the vicinity of the notch 37 of the side plate portion 3 is reinforced by the inner end plate portion 41 and the outer end plate portion 46. Therefore, deformation of the end portion in the longitudinal direction of the side plate portion 3 is suppressed.

  Furthermore, it is further provided with a claw portion 5 that is provided at an end portion in the longitudinal direction of the instrument body 2 and engages with the tip portion 12, and the claw portion 5 is attached to the end plate portion 4 and engages with the tip portion 12, An outer claw portion 51 having elasticity, a claw operation portion 52 that is attached to the end plate portion 4 and depresses the outer claw portion 51 to be elastically deformed to release the engagement between the outer claw portion 51 and the distal end portion 12; Have Thereby, it is suppressed that the lighting fixture 1 remove | deviates from the supporting member 10, and an operator etc. can remove the lighting fixture 1 from the supporting member 10.
