If so, the connecting member 10 has a sufficient service life. That is, since the connecting members 11 and 21 made of different materials are overlapped, the load (stress) is not concentrated, and the shutter curtain 3 having sufficient safety is thereby configured.

  Further, by adopting a configuration capable of obtaining a sufficient strength, the opening / closing speed of the shutter curtain 3 can be improved, so that the opening / closing of the opening 2 can be performed quickly rather than at a low speed as in the prior art. From this, it becomes possible to realize opening and closing in the case where there is a temperature difference between outdoors and indoors, or in an emergency.

  In the above-described embodiment, the connecting member 10 includes the block-like main connecting member 11 and the metal plate-like auxiliary connecting member 21, and the metal plate-like auxiliary connecting member 21 is a part of the main connecting member 11. Although the example of connecting and configuring each other by overlapping on the side has been described, the auxiliary connecting member 21 may be arranged and connected to both the left and right sides of the main connecting member 11. In other words, the resin block-shaped main coupling member 11 is sandwiched between the two metal plate-shaped auxiliary coupling members 21 and coupled. In the case of such a configuration, a through-hole for connecting and fixing the slat 35 is formed in one auxiliary connecting member 21 and configured. According to this configuration, the shutter curtain 3 can be configured with a stronger configuration than the structure of the above-described embodiment, the possibility of breakage and the like can be further reduced, and the opening / closing operation speed can be increased. It becomes.

Furthermore, in embodiment mentioned above, the structure of the connection member 10 is comprised with the block-shaped main connection member 11 and the auxiliary | assistant connection member 21 of a metal plate, ie, comprised by combining in a different shape member with a different material. However, as shown in FIG. 6, a connecting member having the same shape as that of the main connecting member 11 may be used and the auxiliary connecting member 111 may be overlapped.
In the case of this example, since the width of each of the connecting members 11 and 111 is large, it is configured only at the portion of the winding base portion 9 that constitutes a position portion close to the winding wheel 5, and preferably the slat 35 is provided. Connect and fix to the side to be attached. Alternatively, the depth of the guide rail 30 may be sufficiently configured so that it can pass through.
With such a configuration, the reinforcing structure can be configured with the same member as the main connecting member 11 without using the metal plate-like auxiliary connecting member 21 or the like as the connecting member 10. It can be configured.

Moreover, it is good also as a structure which combines the auxiliary | assistant connection member 21 which consists of a metal plate mentioned above, and the auxiliary | assistant connection member 111 formed in a block shape, respectively, and is connected with the main connection member 11, ie, metal is connected to the main connection member 11. The plate-like auxiliary connecting member 21 may be continuously overlapped and connected in the connecting direction, and a block-like auxiliary connecting member 111 may be overlapped and connected to the winding base 9 portion.
With such a configuration, the end edge portion 8 and the winding base portion 9 constituted by the connecting member 10 are obtained with a stronger connection structure.
