  Note that the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the two door panels 15 and 16 are supported by the guide box 12. However, the present invention is not limited to this, and one door panel 15 may be supported by the guide box 12. . In this case, either a configuration in which the width of the door panel 15 is shorter than the width of the guide box 12 or a configuration in which the width of the door panel 15 is longer than the width of the guide box 12 may be used.

  In the above embodiment, the drive device for the door panel 15 is a belt drive system, but the present invention is not limited to this, and for example, a rack and pinion system may be used.

  In the above-described embodiment, the example in which the outer surface of the transparent plate 27 and the outer surface of the outer plate 45 are configured to be substantially flush with each other has been described. The outer surface of the transparent plate 27 and the outer surface of the outer plate 45 may be arranged so as to be flush with each other.

  In the embodiment, the outer plate 45 is in contact with the outer surface of the transparent plate 27 via the seal member 46. However, the present invention is not limited to this. For example, the outer surface of the transparent plate 27 is on the peripheral surface (end surface). It is good also as a structure which the outer plate | plate 45 contacts via the sealing member 46. FIG. Even in this configuration, the outer surface of the transparent plate 27 and the outer surface of the outer plate 45 can be arranged in a flush state.

  Moreover, in the said embodiment, although the transparent plate 27 was set as the structure fixed to the support frame 28 with the caulking material 29, it is not restricted to this. For example, the transparent plate 27 may be fixed to the support frame 28 with a double-sided tape. When the transparent plate 27 is made of a resin such as polycarbonate, the transparent plate 27 may be screwed to the support frame 28.

  Moreover, in the said embodiment, although the translucent member 26 was taken as the structure removed from the door-end side, it is good also as a structure removed from the upper side. In this case, the upper frame is configured as a lid that can be attached to and detached from the frame main body, while the vertical member 57 disposed on the door end side is fixed to the frame main body.
