Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a luminaire that increases an optical output by enlarging a reflector and of reducing an excrescence quantity of protrusion from a frame to a lower part when turning a body of a lighting fitting. SOLUTION: Because of separately disposing a pivot rod 33b for pivotably supporting the body 30 of the lighting fitting with respect to a rotating table 21; and a fixation screw 34 for fixing the body 30 of the lighting fitting on the rotating table 21 in a predetermined turning angle, the need of using a screw as the pivot rod is eliminated, and the pivot rod 33b can be miniaturized. As a result, the reflector 32 can be enlarged to improve the optical output. In addition, the pivot rod 33b is disposed in a position closer to the tip of the body 30 of the lighting fitting than the fixation screw 34, and therefore a protrusion of the body 30 of the lighting fitting from the frame 20 can be minimized when turning the body 30 of the lighting fitting about the pivot rod 33b.
