[Modification]
In the above-described embodiment, the fixed portion 32 of the panel load bearing member 30 is fixed to the vertical frame 23 by means of bolts 328 and nuts 329 as two fixtures passed through screw holes 325 and 326, respectively. Instead, it may be fixed to the vertical frame 23 by three or more fixtures, or may be fixed to the vertical frame 23 by one fixture. Even when the fixed portion 32 is fixed to the vertical frame 23 by a single fixture, the panel load bearing member 30 tilts to the outdoor side and the glass panel 25 is tilted by the contact of the outdoor projections 323A and 323B with the fixed front piece 323. It is possible to suppress falling to the outdoor side.
In the above-described embodiment, the gap 239 is formed between the lower surface 312 of the support portion 31 and the bottom surface 241 of the recess 240. However, the gap 239 may be formed if it does not interfere with the insertion of the lower frame 22 into the panel load receiving member 30. It does not have to be formed.
In the above-described embodiment, the fixed portion 32 has the outdoor protrusions 323A and 323B, but is not limited to this and may have only one of the outdoor protrusions 323A and 323B. Moreover, although the fixing|fixed part 32 has outdoor convex part 323A, 323B and indoor convex part 324A, you may abbreviate|omit these structures.
In the above-described embodiment, the continuous portion 33 is configured to have the hollow portion 331. However, if the panel load receiving member 30 has sufficient strength to receive the panel load, the hollow portion 331 may be omitted.
In the above embodiment, the glass panel 25 is inclined toward the outdoor side with respect to the Y-axis direction, but it may be installed along the Y-axis direction. correspondingly, the upper surface 311 of the support portion 31 of the panel load bearing member 30 may also be arranged along the Z-axis direction and parallel to the lower surface 251 . As a result, a general-purpose setting block 238 having a rectangular cross section can be used.
