PROBLEM TO BE SOLVED: To reduce the manufacturing cost by juxtaposing a plurality of rail members on a roof surface material, arranging a solar battery between the adjacent rail members, covering it with a surface plate, and interposing a coil spring between the rail member and the surface plate. SOLUTION: A roofing 4 having a solar battery 10 is arranged on a roof surface material 2 having a plate material 7 mounted on the upper surface of panel members 6 arranged in lattice, and rail members 3 are juxtaposed on both sides of the roofing 4. A laminated glass surface plate 5 formed of an upper reinforced glass and a lower reinforced glass is mounted between the juxtaposed rail members 3. A coil spring 9 is interposed between the support part 3C of the rail member 3 and the end part 5A of the surface plate 5, one end part 5A of the surface plate 5 is pressed onto the support part 3C of one rail member 3, and the other end part 5A is opposed to the support part 3C of the other rail member 3. Thus, the area for receiving sunlight can be increased. |
