The bearing 10 shown in FIGS. 2 and 3 is left as it is. The intermediate structure 30 for connecting the opening / closing machine 21 and the bracket main body 8A of the supporting bracket 8 is not obstructed by the bearing portion 10 and can be understood from the description below. The bracket body 8A is interposed.

  FIG. 9 shows a front view of the windowed electric shutter device after the manual winding shaft 6 has been modified to the electric winding shaft 20, and in this embodiment, the manual winding shaft 6 is shown. 1 to the electric winding shaft 20, the manual shutter curtain 3 shown in FIG. 1 is changed to the electric shutter curtain 31 shown in FIG. The left and right ends of the electric shutter curtain 31 whose upper end is connected to the electric take-up shaft 20 are slidably inserted into the pair of left and right guide rails 4 shown in FIG. By winding and unwinding by the electric winding shaft 20, the guide rail 4 guides and opens and closes up and down. Therefore, the guide rail 4 is an immovable member that is immovable with respect to the shutter curtain 31, and both end portions in the left-right direction that is the width direction of the shutter curtain 31 are slidably inserted. It is a pair of guide members for guiding the movement. The entirety of the shutter curtain 31 is formed by connecting a large number of slats 32 in the vertical direction, excluding ancillary members such as a seat plate.

  FIG. 10 is a cross-sectional view taken along line S10-S10 of FIG. 9. As shown in FIG. 10, curled portions 33 are formed at the upper and lower ends of each slat 32, and the lower end curl of the upper slat 32A is formed. The portion 33A and the upper end curl portion 33B of the lower slat 32B engage with each other so that the slats 32A and 32B are rotatably connected. Since each curled portion 33 has the same cross-sectional shape in the left-right direction, the curled portion 33 is located away from the pair of left and right guide rails 4, that is, inside the shutter case 5 shown in FIG. In this place, each slat 32 is in a state where it may slide in the left-right direction.

  In addition, when at least a part of the manual shutter curtain 3 shown in FIG. 1 is formed by connecting a plurality of slats, the intermediate structure 30 according to the present embodiment includes the manual winding shaft 6. The present invention can also be applied to the case where the manual shutter curtain 3 is used as the electric shutter curtain after being modified to the electric take-up shaft 20.

It is the switching member 35 for doing this. That is, when the electric shutter curtain 31 whose rotation of the electric winding shaft 20 is stopped because the brake 21D is on is fully opened or fully closed, for example, when a power failure occurs, the switching is performed. When the member 35 is pulled once, the brake 21D is turned off. Therefore, even if the winding shaft is modified from the manual winding shaft 6 to the electric winding shaft 20, the electric winding shaft 20 is restored. Is in a freely rotatable state, and therefore, the electric shutter curtain 31 can be manually opened and closed. When the switching member 35 is pulled once more, the brake 21D is turned on, so the switch 21 returns to the state before the pulling operation described above, and the electric winding shaft 20 is in a state where it cannot rotate freely. Thus, the electric shutter curtain 31 cannot be manually opened and closed.

At the same time, the lid member 44C in which the other end portion (the right end portion in FIG. 11) of the tube member 48 is fitted in the hole 44E is attached to the lower end of the main body 44A of the cap member 44.

  In the present embodiment, the outside of the switching member 35 formed of a wire or the like may be covered with a hollow member. In other words, the switching member 35 may be an inner wire, and the outside of the switching member 35 may be covered with an outer wire.

  As shown in FIGS. 4 and 11, the diameter dimension of the hole 5J of the lid member 5C that is circular or substantially circular is the same as the diameter dimension of the hole 8E of the bracket body 8A that is circular or substantially circular. Or although it is substantially the same, you may make it make the diameter dimension of the hole 5J of the cover member 5C larger than the diameter dimension of the hole 8E of the bracket main body 8A.

  The operator inserts the power cord 39 into the hole 8E of the bracket body 8A, and then inserts the power cord 39 into the hole 5J of the lid member 5C. This insertion operation of the power cord 39 is for supporting the take-up shaft 20. Since it is performed simultaneously with the work of supporting the brackets 7 and 8, the hole 5J of the lid member 5C behind the hole 8E of the bracket body 8A is difficult to see, and the end portion of the power cord 39 inserted through the hole 8E of the bracket body 8A is It is not easy to insert through the hole 5J of the lid member 5C.

  However, by making the diameter dimension of the hole 5J of the lid member 5C larger than the diameter dimension of the hole 8E of the bracket body 8A, the terminal portion of the power cord 39 inserted through the hole 8E of the bracket body 8A is connected to the hole 5J of the lid member 5C. There is almost no need to aim for and pass through. That is, the terminal portion of the power cord 39 inserted through the hole 8E of the bracket body 8A is simply sent out in the direction toward the lid member 5C, so that the terminal portion of the power cord 39 can be easily inserted into the hole 5J of the lid member 5C. Is possible.

  Further, as shown in FIG. 4, the diameter dimension of the hole 5F of the lid member 5B that is circular or substantially circular is the same as or substantially the same as the diameter dimension of the hole 7E of the bracket body 7A that is circular or substantially circular. However, for the same reason as described above, the diameter dimension of the hole 5F of the lid member 5B may be larger than the diameter dimension of the hole 7E of the bracket body 7.

  According to this, the terminal portion of the switching member 35 is easily inserted into the hole 5F of the lid member 5B simply by feeding the terminal portion of the switching member 35 inserted through the hole 7E of the bracket body 7A in the direction toward the lid member 5B. It becomes possible to make it.

Since the first member 61 is disposed at a position far away from the take-up shaft 20, even if the end of the slat 32 that slides in the left-right direction bends downward, it interferes with the intermediate structure 30. Can be prevented.

  In addition, even if the shutter curtain constituting member is wound around the electric take-up shaft 20 while being shifted in the left-right direction, the intermediate construct 30 is configured as long as it does not interfere with or substantially interfere with the intermediate construct 30. The dimension of the part that is a member or the part that is a part of the intermediate structural body 30 is made larger than the diameter dimension D2 of the electric winding shaft 20, and this part is inside the above-mentioned extended diameter dimension. You may make it not enter. An example of this is that the dimensions of the first member 61 and the second member 62 that are located far from the winding shaft 20 and close to the bracket body 8A of the supporting bracket 8 are the electric winding shaft. It is larger than the diameter dimension D2 of 20, and the first member 61 and the second member 62 are prevented from entering inside the above-described extended diameter dimension.
