In addition, as an example of the frame 10, two frame elements 11 a, 11 b, 12 a, 12 b, 13 a, and 13 b formed by metal are connected by connecting members 11 c, 12 c, and 13 c that are heat insulating materials. It is not necessarily limited to this. Further, as the aggregate 21 and the daylighting part aggregate 32, those provided with portions 24 and 36 molded with resin and portions 25 and 37 molded with metal are illustrated, but the portion molded with resin is not necessarily included. You don't have to. In this case, since the parts 25 and 37 formed of metal having a prospective dimension smaller than the distance between the surface materials 22 are applied, there is no possibility that the aggregate or the daylighting portion aggregate becomes a thermal bridge.

  Further, in the above-described embodiment, since the bent fin portion 35 having a plurality of fin shapes is illustrated as the bent portion, the bent portion is continuous over the entire length of the opening edge portion of the daylighting hole 31. Compared to the above, it is easy to bend and the manufacturing work can be facilitated. However, in the present invention, the bent portion does not necessarily have a fin shape. Furthermore, since the connecting member 60 is provided on the daylighting part aggregate 32 via the attachment piece part 43, a dedicated connecting member for connecting the bent part 35 to the daylighting part aggregate becomes unnecessary, and workability is improved. And it is advantageous in terms of manufacturing cost. However, in the present invention, the bent part may be connected to the daylighting part aggregate using a dedicated connecting member. In addition, the bent portions are provided only at the opening edge portions located on the left and right of the daylighting hole 31, but the bent portions may be provided at the opening edge portions located above and below the daylighting hole. Furthermore, you may provide a bending part in the surface material located in a room inner side.
