<p>A wide lower width adjusting section (139) is defined at the lateral lower portion of each of connecting members (A, A min ) disposed at a proper interval, while a wide intermediate width adjusting section (147) is defined at the intermediate portion of the side of the connecting member. The lower portion of the side edge of a lighting frame (B) serving as a roofing member is inserted into the intermediate width adjusting section (147), and the side edge of a water proof sheet (5) laid below the lighting frame (B) is received inside the lower width adjusting section (139). When the total width of the roofing member is greater than the backing width of the roof, the side edge of the lighting frame (B) and that of the water proof sheet (5) are located in positions close to the center of the connecting member (A, A min ). On the other hand, when the total width of the roofing member is smaller than the backing width of the roof, the side edge of the lighting frame (B) and that of the water proof sheet (5) are located in positions close to the outer side of the connecting member (A, A min ).</p> |
