The inner connecting walls 14c, 14c of 14 are cut out and connected to the outer connecting walls 14d, 14d to form a rectangular frame, and a glass 15 is mounted within the frame.

The tip portion 42' of the shoji door mounting wall 42 has a fourth
As shown in the figure, the shoji door mounting wall 42 is bent toward the indoor side from the main body 42'', and an arcuate surface 50 with a radius R ₁ continuous with the outdoor side surface 42''a of the main body 42'' is connected to the indoor side of the main body 42''. It has a side surface 42''b and a continuous inclined linear surface 51, and a notch 52 is formed in the middle of the arcuate surface 50 to divide it into an outdoor arcuate surface 50a and an indoor arcuate surface 50b. It is becoming.

The distal end 45' of the mounting piece 45 is displaced toward the indoor side with respect to the main body 45'', and has an approximately 1/2 circular arc-shaped concave surface 53 having approximately the same radius as the circular arc surface 50. an intermediate portion 45'a that forms, an outdoor side fin portion 45'b that forms a linear inner surface 54 in a tangential direction that is continuous with the indoor side of the arcuate concave surface 53, and an outdoor side fin portion 45'b that is continuous with the indoor side of the arcuate concave surface 53 and It has an indoor side protrusion 45'c forming a linear bent inner surface 55 bent toward the center of the circular arc, and forms a recess that covers the tip 42'.

Because of this, if the tip 45' of the mounting piece 45 is fitted and attached to the tip 42' of the shoji door mounting wall 42 and the mounting piece 45 is placed in a vertical position (the shoji door is closed), the outdoor fin will be The portion 45'b prevents it from coming off toward the indoor side, and the indoor side protrusion 45'c
This prevents it from coming off upward and toward the outdoor side, and when the mounting piece 45 is tilted until the horizontal angle to the indoor side becomes a predetermined angle (θ ₁ ), the outdoor side fin 45'b forms an arcuate surface. Since it is in the tangential direction of 50, it can be removed to the indoor side, and when it is tilted to an angle slightly smaller than this predetermined angle θ ₁ , it will not come off as described above, and in fact, it is regulated to be tilted to an angle of θ ₂ .

Therefore, in order to install the lower shoji door 16, as shown in _FIG . 42'. At this time, the outdoor side fin portion 45'b plays the role of a guide for fitting. Then, the fitting part is tilted toward the outdoor side, and the other end of the arm 26 is tilted toward the vertical stile 14.
The lower shoji door 16 is pivotally connected to the outer connecting wall 14d of the lower shoji door 16 via a block 27, and a stopper 28 that restricts the downward sliding of the slider 25 is fixed to the groove 20d of the auxiliary vertical frame 20 with screws. The angle of inclination towards the indoor side is restricted to (90° - θ ₂ ).

Then, the indoor vertical wall 3a and the upper horizontal wall 3b of the lower frame 3
