7) is a fixed cover body (25) in FIGS. 1 and 2.
Like the side cover piece (251), the side cover body (27) is supported on the step plate (221) of the frame support (22) on the side where the frame member (32) is not attached. It has a cover support section (271) and a tile holding section (272) for pressing the end of the tile (13) onto the roof base material (10). Therefore, in this side cover body (27), since the side cover piece (251) is separate from the fixed cover body (25), the tile cover of the side cover piece (251) is held down. It can be said that the part (253) (= the tile material holding part (272) in the side cover body (27)) is necessarily separate from the fixed cover body (25). In this case, since the side cover piece (251) of the fixed cover body (25) is separate as the side cover body (27), the fixed cover body (25) is a normal fixed cover body (25). 21). For this reason, in FIG. 3, it is described as a fixed cover body (21). Further, in the embodiment of FIG. 3, a waterproof member (7) is attached to the lower surface of the tile material holding portion (272) of such a side cover body (27).
