The shutter 75 is configured by incorporating the panel 15 in a cage set composed of an upper cage 14a, a lower cage 14b, and left and right vertical rods 14c, 14c.

  The upper slide rail 4 includes an upper fixed rail 4a provided on the upper frame 3a, and left and right upper movable rails 4c supported slidably on the upper fixed rail 4a via an upper intermediate rail 4b. The upper movable rail 4c is provided on the back surface of the shutter 75, that is, on the back surface (interior surface) of the upper roof 14a. The shutter 75 is configured to be held by the upper slide rail 4 in a state of protruding outward from one of the vertical frames 3c (left side in FIG. 9) when fully opened.

Further, the lower end of the shutter 75 is supported through the lower slide rail 30 so as to be slidable.
In the shutter open state, the shutter 75 is held by the upper and lower slide rails 4 and 30 so as to protrude outward from the one vertical frame 3c.

Even with such a shutter device 75, as with the shutter device 1, it is possible to prevent the shutter 5 from fluttering or falling when the shutter is fully open, and to reduce the opening / closing force of the shutter 5.
Further, even if the weight of the shutter 75 increases, the shutter can be slid open and closed more smoothly and with no fluttering in the out-of-plane direction.

Further, in this shutter device 71, a lower catcher is provided only at the lower end portion of the shutter 75, and a lower catcher receiver is provided in the lower frame 3b to hold the lower end portion of the shutter when the shutter 75 is fully opened to prevent the shutter from falling. do it.
When the shutter 75 is fully closed, since the shutter 75 can be locked by the lock 35, the upper catcher and the upper catcher receiver need not be provided.

  In the first to third embodiments, the lower slide rail 30 is used to support the lower portions of the shutters 5, 54, 55, 75. However, the structure of the lower slide rail is not limited to this. For example, the same structure as the upper slide rail 4 may be used.
