<p>PURPOSE:To enable a screw, penetrating a penetraton hole constructed in an elastic piece, inserted to be screwed to a screw hole of mounting frame with a flexibility of the elasftic pisce toward a side of the mounting frame, even for the mounting frame positioning below a level of wall, by means of providing the penetration hole in the elastic piece installed to a plate frame. CONSTITUTION:A plate 3 is detachably installed to a side of front surfaces of a plate frame 2 of a flash plate 1. A screw 12, 12', that penetrates a penetration hole 5, 5' formed in the plate frame 2, is installed to be screwedf to a screw hole 11, 11' of a mounting frame 10 installed to a disftributing box 8 embedded in a wall face 7. The penetration hole 5, 5' will be formed in an elastic piece 4, 4' installed to the plate frame 2. By an insertion serewing of the screw 12, 12', that penetrates the penetration hole 5, 5', to the screw hole 11, 11', rear faces of the plate frame 2 will be attached to te wall face.</p> |
