Therefore, the pressing pieces 8, 8 of the left and right mounting pieces 15, 15 are made to face each other in a substantially inverted C-shape, and the connecting pieces 18 are connected to the supporting portions 7, 7 of the left and right mounting pieces 15, 15. Connecting piece 1
The tight frame 6 is formed by welding 7 and 17, for example, and forming the holding portion 12 between the tip of the connecting piece 17 and the upright piece 14. In this case, the height of the upright piece 14 is set to the gutter member 9
Is almost equal to the height of. The gutter member 9 has a substantially U-shaped cross section with an opening at the top and extends over the entire length in the eaves direction, and the upper ends 11, 11 of the side walls 10, 10 are folded back to provide elasticity. Both side walls 10 and 10 are inclined so that the upper side of the gutter member 9 is directed outward.

In such a structure, the gutter member 9 is arranged on the roof substrate 20, and is fixed at the end on the ridge side, for example, and the tight frame 6 is attached to the roof substrate 20 with a screw or the like in the mounting piece 13. The gutter member 9 is fixed.
The upper end portion 11 of the above is elastically inserted into the holding portion 12 of the tight frame 6, and the gutter member 9 is pressed and fixed to the roof base 20. Next, the pressed piece 5 of one roof material A is passed between the left and right pressing pieces 8 and 8, and the pressed piece 5 of the other roof material A is passed between the left and right pressing pieces 8 and 8 Part 4 and recess 3
And fit together.

According to this structure, the pressed pieces 5, 5 of the roofing materials A, A to be connected are located below the pressing piece 8, and the pressed piece 8 is pressed by the pressing piece 8.
The convex portion 4 and the concave portion 3 are fitted to each other, and the connection pieces 2 and 2 are firmly brought into contact with each other to enhance watertightness. Therefore, the cap provided at the connection portion of the roof materials A and A can be omitted, and the configuration is simplified. Of the gutter member 9 and the upper end portions 11 of the gutter member 9 are elastically displaced and held by the holding portion 12 of the tight frame 6 together with the elastic displacement of the side wall 10. The gutter member 9 can be firmly attached to the roof substrate 20 at a predetermined position.

In this case, the tip of the connecting piece 17 and the standing piece 1
4 and a holding portion 12 formed between the upper end portion 11 of the gutter member 9
Can be inserted and held, and the structure of the holding portion 12 can be simply configured.

Further, since the pressed piece 5 is folded back substantially horizontally, the pressed piece 8 can be stably pressed by the pressing piece 8 and the connection between the roof members A, A can be stabilized. You can do it.
