The setting section cover 233 and the setting section case main body 234 form a setting section case 235.

That is, in the lighting fixture 200 according to the modification, the setting section cover 233 may be in contact with the setting section case main body 234 and movable between the normal position P1 and the setting position P2.
Since the lighting fixture 200 is configured as described above, the setting work can be performed without removing the setting section cover 233 from the setting section case body 234. Therefore, at the time of setting work, there is no need to worry about the place where the removed setting section cover is placed, or to lose the removed setting section cover.
