In addition, the front lower hinge 4 is structured to be fitted into and removed from the fitting hole 40 of the movable bracket 31 with respect to the hinge shaft 29 of the fixed bracket 27, and the front upper hinge 3 is movable to the hinge shaft 28 of the fixed bracket 26. Since the guide portion 41 of the bracket 30 is aligned from the side, the hinge shaft 28 is guided to the fitting hole 39 of the movable bracket 30 while guiding the hinge shaft 28 with the guide portion 41. The structure of the hinge 3 and the front lower hinge 4 can be greatly simplified. For this reason, the front upper hinge 3 and the front lower hinge 4 can be easily and inexpensively manufactured as compared with the prior art, and the durability of the front upper hinge 3 and the front lower hinge 4 is improved.

  When the front frame 2 is attached to the outer frame 1, after the front lower hinge 4 is joined, the front upper hinge 4 is supported on the front upper hinge 4 while the guide 41 of the front upper hinge 3 is aligned with the hinge shaft 29. 3 is moved from the side to the hinge shaft 28 side of the fixed bracket 26, the hinge shaft 28 fits into the fitting hole 39 while lifting the front frame 2 through the guide 41 and the movable bracket 30. Therefore, there is no need to lift and fit the front frame 2 and the front frame 2 can be attached to the outer frame very easily.

  When the front frame 2 is mounted, the upper and lower hinge shafts 28 and 29 are fitted in the fitting holes 39 and 40 of the movable brackets 30 and 31, so that the front frame 2 can be easily and around the hinge shafts 28 and 29. It can be pivoted to open and close reliably.
