The insertion portion 51 of the pressing member 5 includes an eaves-side molded portion 23 of an exterior material (in the illustrated embodiment, an exterior material integrated solar energy conversion device 1) laid on the ridge side, and an exterior material integrated type laid on the eave side. The solar energy conversion device 1 is a portion that is positioned by insertion or the like at the joint portion with the ridge-side molded portion 22, and the shape thereof is not particularly limited. The insertion part 51 will be described in more detail. There are (1) an aspect in which no retaining part is provided and (2) an aspect in which a retaining part is provided.
As an aspect of the above (1), there is an example in which the insertion portion 51 is positioned at a joint portion and fixed by adhesive, double-sided tape, or the like.
When the insertion part 51 is fixed by pasting, the place where the adhesive and the double-sided tape are provided may be any of the eaves side molding part 23, the ridge side molding part 22 and the insertion part 51 of the pressing member 5, and at least one place is provided. Just do it.
When the insertion part 51 is fixed by clamping, the eaves-side molding part 23 and the ridge-side molding part 22 may be any one of the ridge end, the eaves end, and the middle part of the insertion part 51, and may be clamped at least one place. .
As an aspect of the above (2), the retaining portion may be any structure as long as the pressing member 5 does not fall off in the assembled state, and includes a member that prevents the retaining member 5 from being removed by fitting, locking, or the like.
