The lifting of the guide body 43 itself can be prevented by the stop. Reference numeral 45 denotes a packing material for ensuring airtightness between the front surfaces of the lower frame 12 and the upper frame 11 and the rear surface of the door 2. Further, opaque portions 47 are formed or provided at the upper and lower ends of the opening and closing door 2 so as to hide (hide) the open portions (outward open portions) which are the front surfaces of the lower frame 12 and the upper frame 11. As shown in FIG. 1, FIG. 2 and FIG. 4, opaque films 46a and 46b of appropriate colors are stuck to the upper and lower ends of the back side of the opening and closing door 2 as shown in FIGS. In this case, it is preferable to attach the opening and closing door 2 to the upper and lower crossbars 23 before fixing it with the adhesive 24, and to attach the band-shaped films 46 a and 46 b uniformly over the entire length in the frontage direction of the opening and closing door 2. At this time, it is preferable that the location of the packing material 45 is also hidden. Further, a portion where the hinge means 10 is disposed, a roller 42 serving as the hanging-down preventing means 39, its bracket 40, and a guide body 43 may be hidden. The structure of the opaque portion 47 may be a band-shaped thin metal plate or a coating.

The upper frame 11 and the lower frame 12 may have an L-shaped cross section, with the free ends of the horizontal sides facing outward, and the vertical sides located at the back of the case body 1. And an upper frame 11 made of a square pipe or a round pipe.
The lower frame 12 may be formed so that notches are formed so that only the attachment portion of the hinge means 10 and the arrangement position of the roller 42 as the hanging-down prevention means 39 become a front open portion.

According to the above configuration, as shown in FIGS. 5 and 6, when the opening / closing door 2 closes the opening of the frontage of the case body 1, the first link 14 and the second upper Most of the longitudinal direction of the link 27 and the second lower link 28 will fit in the support bracket 13 via the outward openings in the lower frame 12 and the upper frame 11,

6a and 46b are located at the upper and lower portions of the door 2,
The presence of the hinge means 10, the existence of the open upper frame 11 and the lower frame 12, and the like outward are hidden, so that the appearance can be improved. In addition, since the upper frame 11 and the lower frame 12 are open outward, the effect of extremely easily installing and fixing the support bracket 13 in each hinge means 10 is achieved.

As can be understood from FIG. 9, when the opening / closing door 2 is opened by approximately 90 degrees with respect to the front surface of the case body 1 in a plan view, the opening / closing door 2 is prevented from rotating further. The middle part of the one link 14 abuts on the side surface of the second fixed shaft 29 on the base end side of the opening / closing door 2 and can be prevented from opening at an angle larger than that. By devising the shape of the first link 14 in a plan view, the maximum opening angle of the door 2 can be arbitrarily adjusted. Further, as shown in FIG. 1, a stopper link 50 having a base end horizontally rotatably attached to an outwardly open upper frame 11 or lower frame 12 of the case main body 1 is provided with a stopper link at the upper and lower portions of the door 2. 23 may be rotatably connected via a flange (not shown) to prevent the door 2 from opening beyond a predetermined angle.

Also, the present invention is applicable to a structure in which a connecting member of the hinge means 10 to the opening / closing door 2 side and a bracket 40 as a hanging-down preventing means 39 are attached without inserting the bar 23. It goes without saying that you can do it.
