  Next, the configuration of the lower frame 11 will be described in detail. 3 is an enlarged view of the vicinity of the lower frame 11 in FIG. 1, and FIG. 4 is an exploded cross-sectional view of the lower frame 11. As shown in FIG. 3, the lower frame 11 is configured by providing a resin lower frame 25 so as to cover a room-side exposed surface of the metal lower frame 20. As shown in FIG. 4, the metal lower frame 20 is formed in a hollow cross section, and a screen door rail 22, an outer rail 21, and an indoor rising piece 23 are formed in a protruding shape on the upper surface in order from the outdoor side. The screen door rail 22, the outer rail 21, and the indoor rising piece 23 are all formed so that their upper end positions are substantially the same height. The resin lower frame 25 includes an upper surface covering member 26 provided so as to cover the upper surface of the metal lower frame 20 and an indoor surface covering member 27 provided so as to cover the indoor side surface of the metal lower frame 20.

  As shown in FIG. 4, a large concave region is formed between the outer rail 21 and the indoor rising piece 23 on the upper surface of the metal lower frame 20, and the upper surface covering member 26 constituting the resin lower frame 25 in this region. Is installed. The upper surface covering member 26 has a substantially L-shaped cross section with an upper surface covering portion 26 a covering the upper surface of the metal lower frame 20 and a rising covering portion 26 b covering the outdoor surface of the indoor rising piece 23 of the metal lower frame 20. It is formed into a shape.

  A resin frame engaging piece 24 is formed in a protruding shape on the upper surface on the indoor side of the outer rail 21 of the metal lower frame 20, and the upper end covering member 26 engages with the resin frame engaging piece 24 at the outdoor end. To do. Further, an engaging portion 23a is formed near the upper end of the indoor rising piece 23, and the rising covering portion 26b of the upper surface covering member 26 is engaged and fixed.

  The inner rail member 30 is placed on the upper surface of the upper surface covering member 26. The inner rail member 30 is made of a metal material, and includes a base 31 placed on the upper surface covering member 26 and an inner rail 32 formed so as to protrude upward from the base 31. The upper end position of the inner rail 32 is set to be substantially the same as the upper end position of the outer rail 21 or the indoor rising piece 23.

  An inner rail engaging portion 26c for engaging the base portion 31 of the inner rail member 30 is formed on the upper surface covering portion 26a of the upper surface covering member 26, and the base portion 31 of the inner rail member 30 is connected to the inner rail engaging portion 26c. While being engaged, it is fixed to the upper surface covering member 26 by screwing. The screw 28 used for fixing passes through the upper surface of the metal lower frame 20 and reaches the hollow interior, thereby fixing the inner rail member 30 to the metal lower frame 20 as well.

  Thus, the inner rail 32 is provided on the inner rail member 30 formed of a metal material separate from the metal lower frame 20, and the inner rail member 30 is placed and fixed on the upper surface covering member 26 made of a resin material. Therefore, the inner rail 32 is thermally insulated from the metal lower frame 20. Therefore, while ensuring the strength of the inner rail 32 that supports the load of the inner impeller 2, it is possible to prevent the heat insulation from being deteriorated due to the exposure to the indoor side.

  An intermediate upper surface member 34 is provided in the region between the inner rail 32 and the outer rail 21 over substantially the entire length in the longitudinal direction. The intermediate upper surface member 34 is formed of a metal material, and the upper surface 34 a extends from the vicinity of the outdoor surface of the inner shuffler 2 to the vicinity of the door 7 of the outer obstacle 3, and the upper end of the inner rail 32, the outer rail 21, and the indoor rising piece 23. It is formed to be approximately the same height as the position.

  In order to fix the intermediate upper surface material 34 to the lower frame 11, an upper surface material attachment component 35 is provided on the upper surface of the outdoor end portion of the upper surface covering member 26. The upper surface material mounting part 35 is formed as a small piece part made of a resin material, and a plurality of the upper surface material mounting parts 35 are provided at predetermined intervals along the longitudinal direction of the lower frame 11. The upper surface material attachment component 35 has a base portion 35a attached to the lower frame 11, and an engagement piece 35b for fixing the intermediate upper surface material 34 is provided on the upper surface thereof.

  A lower surface engaging portion 35d that engages with a concave portion 29 formed by the outdoor end portions of the upper surface covering member 26 and the inner rail member 30 is formed on the lower surface of the upper surface material attachment component 35 so as to face the indoor side. Further, an inverted J-shaped elastic engagement portion 35 c is formed on the outdoor surface of the upper surface member mounting component 35. Since the elastic engagement portion 35 c is formed in a thin plate shape, the elastic engagement portion 35 c has elasticity in the indoor / outdoor direction, and its tip engages with the flange portion 21 a formed near the upper end of the outer rail 21. The upper surface member attachment component 35 is biased to the indoor side. Thereby, the lower surface engaging portion 35d is pressed against the concave portion 29 side, and the upper surface material attachment component 35 is fixed to the lower frame 11.

  The intermediate upper surface member 34 has a mounting portion 34 b on the lower surface, and the intermediate upper surface member 34 is attached to the upper surface member mounting component 35 by engaging the mounting portion 34 b with the engaging piece 35 b of the upper surface member mounting component 35.
