Then, when engaging the net side hook member 21b with the shutter side hook member 15b, if the connecting member 21c does not have flexibility, the net side hook member 21b is bent indoors (right side in FIG. 7). It becomes difficult to engage.

  In view of this point, in the example shown in FIG. 7B, the net-side hook member 21b is attached to the insect-proof net 21 via a flexible connecting member 21c, and therefore the connecting member 21c is bent indoors. However, since the net side hook member 21b can be engaged with the shutter side hook member 15b, the workability of the engagement can be improved. Incidentally, if the connecting member 21c is configured not to be inserted into the guide rail 16, the connecting member 21c can be more easily bent to the indoor side, which is preferable.

  The example shown in FIG. 7A is also configured in view of this point, and the hook members 15b and 21b are engaged by using a single hook member 26 that is not fixed to the shutter curtain 11 and the insect net 21. Therefore, it is unnecessary to engage the insect-proof net 21 while bending it, and the workability of the engagement can be improved.

[Other Embodiments]
The present invention is not limited to the description of the above embodiment, and the characteristic structures of the above embodiments may be arbitrarily combined. For example, you may implement as follows.

  In each of the above embodiments, a roll type in which the insect net 21 is wound around the insect net winding drum 23 and stored in the insect net storage case 22 is adopted. However, the insect net 21 is folded to the insect net storage case 22. A folding type for storing may be adopted. Further, the shutter curtain 11 and the insect net 21 according to the present invention are not limited to one that opens and closes in the vertical direction, and may be one that opens and closes left and right, for example.

  In each of the embodiments described above, the guide rail 16 that guides the shutter curtain 11 also serves as a guide rail that guides the insect net 21. However, the shutter curtain 11 and the insect net 21 can be connected to each other so as to be interlocked. For example, the guide rail of the insect net 21 may be provided separately from the guide rail 16 of the shutter curtain 11. Further, the guide rail 16 that guides the shutter curtain 11 also serves as a guide rail that guides the insect-proof net 21, and the shutter curtain 11 only has to be arranged on the same surface with the outer surface of the shutter curtain 11 and the outer surface of the insect-proof net 21. The curtain 11 and the insect net 21 need not be connected.

  Although the shutter device 10 according to each of the above embodiments is a manual type, it may be an electric type that opens and closes the shutter curtain 11 by an actuator such as an electric motor.
