In the roof structure where the metal tiles are roofed side by side, locking edges with locking pawl insertion holes drilled in the front and back are provided on both sides of the metal tiles, and an insertion engagement portion is provided on the front edge, and a receiving engagement portion is provided on the rear edge. The upper surface of the rafter is provided with a locking groove for receiving the locking edge of the metal tile on both sides of the upper part, a locking claw to be inserted into the locking insertion hole, and a fixing claw protruding from approximately the center of the upper part. A tight frame is provided in an upright manner between the front and rear locking claw insertion holes of the metal tiles described above, and the insertion and engagement portions of the vertically adjacent metal tiles are engaged with each other, and the locking edge Align the rear locking insertion hole with the front locking claw insertion hole, insert into the locking claw of the tight frame and fix it, and insert the rear insertion hole into the connecting part of the metal tiles adjacent to the left and right. Attach the opened sill cover and insert the fixing claw of the tight frame into the insertion hole to hold the sill cover, and attach the decorative part of the upper sill cover to the fixed part of the lower sill cover. It is what it is.
