The sash 5 is provided on the upper frame and the outer surface of the sash 51.
1 is attached via an inner magsa 52 having a substantially horizontal protruding piece protruding outward over substantially the entire width.

As described above, in the present embodiment, the shutter box 1 is replaced with the main unit 21 except that the lower cover 35 is replaced with a lower cover 50 for an external sash.
The upper side cap 22 and the lower side cap 36
The same components are used.

The lower cover 50 extends downward from the height of the recess 23 and covers the lower half of the front face of the box body 2. The lower plate 50A is bent inward from the lower edge of the front plate 50A. And a lower plate piece 50B extending to the shutter entrance / exit 29.

The front plate 50A has a hook 37 at its upper edge, which engages with the locking piece 24, similarly to the front plate 35A. In this example, the lower plate piece 50B is screwed and fixed to the outer fixed piece 27A via the bent portion 39, and its inner end is bent upward along the inner edge of the outer fixed piece 27A. Terminated. Therefore, in the lower cover 35, the shutter entrance / exit 29 formed inside the inner fixed piece 27B can be formed in the lower cover 50 of the present embodiment toward the outer fixed piece 27A.

As described above, since the lower covers 35 and 50 can be exchanged with each other, it is possible to cope with both the internal sash and the external sash while sharing other components such as the box body 2. And the box body 2
Since the size of the device can be made as small as possible, the size of the device can be reduced. In addition, along with the miniaturization, the design of the entire house can be improved, and the mountability to a corner can be improved.

[0037]

Since the present invention is configured as described above,
By removing the lower cover part, the inside of the box body can be greatly opened, maintenance can be performed reliably and with high precision, and the weight of the installation work can be reduced. Only exchange is possible.

Further, by adopting the structure of claim 2,
The weight reduction of the work can be further promoted, and furthermore, by replacing only the lower cover, it is possible to cope with both the internal sash and the external sash.

In addition, when the box body is mounted with the upper surface of the box body protruding from the back surface of the eaves ceiling, the effect of improving the maintainability can be exhibited.
In addition, the design can be improved by improving the appearance of only the lower cover part that is mainly exposed to the outside, and the replacement of the lower cover part alone makes it appear that the entire shutter box has been replaced. Can change the design.
