An interconnecting piece is formed extending between and attached to the structural housing by connecting the connecting piece to the structural housing. Therefore, when replacing the window frame due to deterioration of the window frame, etc., it is necessary to at least partially destroy the outer wall since the detachment of the window frame from the structural frame is inhibited by the outer wall.

  Therefore, according to Patent Document 1 below, the window frame is surrounded by a molding frame formed separately from the window frame, and each connecting piece of the upper horizontal frame member, the lower horizontal frame member, and both vertical frame members of the window frame is molded A sash structure in the form of being covered by a frame is disclosed. In this sash structure, the molding frame is located closer to the window frame than the side edges of the outer wall, and the connecting pieces of the upper horizontal frame member, the lower horizontal frame member, and both vertical frame members of the window frame are covered by the molding frame. But it is not covered by the outer wall. Therefore, when replacing the window frame, if the molding frame connected to the structural frame is detached from the structural frame, the window frame can be detached from the structural frame without destroying the outer wall.
