[0012]

[Function] The edges of the flanges are erected on opposite sides,
Because the end faces of the flanges vertically overlap in a U-shaped cross section and the two flanges are abutted and integrated, even if the hand touches the side wall of the upright surface from the side, the fingertip hits the side wall of the upright surface, Burr contact is reduced. In addition, since the end of the raised surface of the flange disposed outside does not protrude from the flange surface, burrs do not come out above the flange surface, and even if the hand touches the side wall of the raised surface from above and below, the fingertips Burr contact is reduced. In addition, when the upright surface of the reflection shade is arranged outside the upright surface of the fixture body, the overlapping portion of the upright surface is not visually recognized from below, so that a lighting device with a good appearance can be obtained. Further, since the end of the upright surface facing the notch for leading out the lamp cord is curled, damage to the lamp cord is prevented. Further, the reflection shade can be accurately positioned only by engaging the projections on both sides of the notch with the side ends of the curling, thereby facilitating assembly.
