確実に防止できる。When the thickness of the ceiling T is large, the gentle slope 9b can be brought into contact with the inner peripheral wall T2 of the hole T1 of the ceiling T as shown in FIG. When the thickness of the ceiling T increases, the elastic piece 2 is pressed toward the main body 1 by the inner peripheral wall T2 of the ceiling T accordingly. For example, the pressing piece 9 of the elastic piece 2 is In the case where only the steeply inclined portion is provided without being provided, the steeply inclined portion becomes nearly vertical (indicated by a dashed line in the drawing), and the inner peripheral wall T2 is easily slid downward. As a result, the possibility that the lighting fixture shifts downward due to its own weight increases. However, as in the present invention, the gently inclined portion 9a is further bent outward from the main body portion 1 at a predetermined angle A from the steeply inclined portion 9a to form the gentle inclined portion 9b into the inner peripheral wall T2.
When the ceiling T is thickened, the gently inclined portion 9b can be maintained in a state of being inclined outwardly of the main body portion 1 and can be prevented from slipping downward. Therefore, it is possible to reliably prevent the lighting fixture from rubbing downward on the perforated hole T1 due to its own weight.
