In the blind device 1, since the blind frame part 2 is a three-sided frame without a lower frame, compared with a four-sided frame with a lower frame, there are fewer barriers to the outer wall, and wind intake performance can be improved.
Also, the labor and cost required for manufacturing and attaching the lower frame can be reduced.

The first lower end cap 26 and the second lower end cap 27 are fixed to the outer wall 11 so that the first lower end cap 26 and the second lower end cap 27 are attached to the slats 41 . When a load is applied, this load can be received by the outer wall 11 .

In the first blind vertical frame 22 and the second blind vertical frame 23 (a pair of vertical frames), the guide rail 231 is provided and the area located on the side of the slat 41 has a dimension in the direction of projection larger than that of the slat 41 in the direction of projection. is set large, the ends of the slats 41 are covered with the first blind vertical frame 22 and the second blind vertical frame 23, so that the ends of the slats 41 are prevented from coming into contact with people or objects. can be done. In addition, the vertical frame can block sunlight coming in from the side of the opening 12 .

Although the embodiments of the blind device according to the present invention have been described above, the present invention is not limited to the above embodiments, and can be modified as appropriate without departing from the scope of the present invention.
For example, in the above-described embodiment, the first vertical blind frame 22 and the second vertical blind frame 23 are set so that the dimension in the direction of projection is larger than the dimension in the direction of projection of the slats 41, but the first vertical blind frame 22 And the dimension of the second blind vertical frame 23 in the prospective direction may be set as appropriate.
Also, although the first lower end cap 26 and the second lower end cap 27 are fixed to the outer wall 11 in the above embodiment, they may not be fixed to the outer wall 11 .

Further, in the above-described embodiment, the bracket 43 to which the blind box 42 is attached is provided with the opening/closing portion 432 for opening and closing the blind box accommodating portion 437, and the blind box accommodating portion 437 of the bracket 43 is opened downward so that the bracket A blind box 42 is attached to 43 from below. On the other hand, the bracket 43 may be configured so that the blind box 42 can be inserted from the side. By doing so, the blind box 42 can be easily installed on the bracket 43 .
In the above embodiment, the blind box 42 is positioned in the left-right direction by bringing the blind box 42 into contact with the vertical frame fixing portions 311 of the first upper wall fixing bracket 31 and the second upper wall fixing bracket 32. A member other than the above may be provided as a positioning member in the horizontal direction of the box 42, or a positioning member in the horizontal direction may not be provided.

Moreover, although the sash 13 is a single sliding door in the above embodiment, it may be a double sliding door.
Moreover, although the first blind vertical frame 22 and the second blind vertical frame 23 are separated from the outer wall 11 in the above embodiment, they may be in contact with the outer wall 11 . Alternatively, the first blind vertical frame 22 and the second blind vertical frame 23 may be directly fixed to the outer wall 11 .
