PROBLEM TO BE SOLVED: To improve workability by arranging an opening to insert an engaging piece on the reverse of a natural lighting body in a rail main body, and arranging a restricting member to lock the engaging piece in the opening. SOLUTION: Support rails 2 are fixed in plural rows toward the eaves side from the ridge side on a roof. The rails 2 have a rail main body composed of cross-sectional C-shaped rails of two rows, and for example, the projecting part 11a thickly formed in the tip part of a first engaging piece 11 arranged in left/right frame members 42 of a solar battery module 4, is inserted into an opening 22 formed in a rail 21. A restricting member 24 having the cutout part 23 being the engagement receiving part of the engaging piece 11 is movably arranged in the rail 21. Next, the member 24 is positioned by locking a projecting piece 25 orthogonally arranged to the lengthwise direction of the rails 2 on the end part 21a of the rail 21. The vertical direction of the module 4 is restricted by one end part 26 of the member 24, and the lateral and height directions are restricted by the cutout part 23. Therefore, slip-down in a temporarily placing state at installing time can be prevented by easily/firmly fixing a fixing structure. |
