In this case, the lighting fixture main frame 20 is made to abut on the box 14 buried in the wall, and is positioned so that the peripheral edge of a front surface frame 22 is aligned with the tile joints accurately. This condition is maintained, and while fastening positions of screws 44 are marked off in a bracket 16. Next, the lighting fixture main frame 20 is removed once, and tap holes are drilled in the marking-off position of the bracket 16. Thereafter, the lighting fixture main frame 20 is made to abut on the box 14 buried in the wall again, and the peripheral edge of the front surface frame 20 thereof is aligned with the surrounding tile joints, and the screws 44 are fastened under this condition to fix the lighting fixture main frame 20. |
