  As shown in FIG. 5, the outdoor surface material 7 is formed by cutting out the planned opening portions 40 to 42 indicated by the oblique lines of a single steel plate 77 by press punching, and then the side edge of the opening is along the planned bending line α. Then, it is bent to the indoor side by press working, and then the side edge of the opening is further bent to the indoor side by press working along the planned bending line β. A bent portion bent along the planned bending line α is referred to as a first bent portion 45 (a tip portion of the side edge of the glass opening 6), and a bent portion bent along the planned bending line β is a second bent portion 46 ( This is called the side edge of the glass opening 6 of the outdoor surface material 7.

  6 is an enlarged view of an arrow A portion in FIG. The outdoor surface material 7 and the glass frame 9 are fitted in the following procedure. However, the glass 15 does not exist at the time of fitting as described above. First, the glass frame 9 at the position indicated by the broken line is pushed in the direction indicated by the arrow B toward the outdoor surface material 7 from the position indicated by the broken line. At this time, the bent portion 47 of the glass frame 9 pushes the first bent portion 45 of the outdoor surface material 7 in the pushing direction (B direction), and simultaneously, the second bent portion 46 of the outdoor surface material 7 is moved in the direction of arrow C. Push away. Further, when the glass frame 9 is pushed in the direction indicated by the arrow B, the bent portion 47 of the glass frame 9 gets over the first bent portion 45 of the outdoor surface material 7, thereby the outdoor surface material 7 and the glass. The frame 9 is fitted. In other words, the middle frame 10 of the glass frame 9 is held inside the first bent portion 45 of the outdoor surface material 7 and the second bent portion 46 of the outdoor surface material 7. At this time, since the first bent portion 45 of the outdoor surface material 7 is located on the indoor side from the tip of the bent portion 47 of the glass frame 9, the glass frame 9 performs a temporary fixing function and falls off the outdoor surface material 7. There is nothing.

  Moreover, since the bending part 47 of the glass frame 9 is suppressed by the restoring force (force in the direction opposite to the arrow C) of the second bending part 46 of the outdoor surface material 7, the glass frame 9 becomes the outdoor surface material 7. It is firmly fixed.

  The width W of the first bent portion 45 of the outdoor surface material 7 is set to be 4 to 5 mm from the front end portion 45 a of the side edge of the glass opening 6 of the outdoor surface material 7. If the width W of the first bent portion 45 is too small, the glass frame 9 is easily pulled out from the outdoor surface material 7. If the width W of the first bent portion 45 is too large, the glass frame 9 is This is because it is difficult to fit into the outer surface material 7.

  Since the first bent portion 45 is formed on the outdoor surface material 7, there is no edge (for example, a cut surface) at the base end 45 b of the first bent portion 45, and when the glass 15 is wiped through the opening 32, a hand or the like There is no risk of damaging the battery and safety is ensured.

  The bending angle θ1 of the first bending portion 45 of the outdoor surface material 7 is set to be 45 degrees with respect to the plate surface 15a of the glass 15, but even when the bending angle θ1 is other than 45 degrees, the room It is only necessary that the glass frame 9 is fitted inside the first bent portion 45 and the second bent portion 46 of the outer surface material 7 and the glass frame 9 can be fixed to the outdoor surface material 7.

  The bending angle θ2 of the second bending portion 46 of the outdoor surface material 7 is 90 degrees. When the bending angle θ2 is larger than 90 degrees, the second bent portion 46 of the outdoor surface material 7 projects toward the opening 32 and passes through the opening 32 from the outdoor side to the second bent portion 46 of the outdoor surface material 7. Will appear, and the appearance will deteriorate. On the other hand, when the bending angle θ2 of the second bent portion 46 of the outdoor surface material 7 is set to be smaller than 90 degrees, the glass frame 9 may not fit into the outdoor surface material 7 if it is too small. Therefore, the bending angle θ2 of the second bent portion 46 of the outdoor surface material 7 is set to an appropriate angle within a range where the glass frame 9 is fitted and the appearance is not impaired.

  In the above embodiment, the glass frame 9 is made of aluminum, but it may be made of steel or resin other than aluminum. In addition, although the three frame openings 8 of the glass frame 9 and the glass openings 6 of the outdoor surface material 7 are provided, the number of the glass openings 6 and the frame openings 8 may not be three. The bent portion 47 of the glass frame 9 is formed in a bowl shape that opens to the indoor side, but the first bent portion 45 of the outdoor surface material 7 and the first surface of the outdoor surface material 7 are not spread to the indoor side. The bent portion 47 of the glass frame 9 may be fitted inside the second bent portion 46 and the glass frame 9 may be fixed to the outdoor surface material 7. Although the width W of the first bent portion 45 of the outdoor surface material 7 is set to 4 to 5 mm, the first bent portion 45 of the outdoor surface material 7 and the outdoor surface material 7 are outside the range of 4 to 5 mm. The glass frame 9 may be fitted inside the second bent portion 46 and the glass frame 9 may be fixed to the outdoor surface material 7. Although the outdoor surface material 7 is bent only in the longitudinal direction (longitudinal direction) of the glass opening 6, it may be bent in the short direction (lateral direction).

  The above-described embodiments are merely one aspect of the present invention, and can be arbitrarily modified within the scope of the present invention.
