Even when adjusting the positional deviation of the door 15 after installing and using the storage, the door 15 is opened and the first and second screwing portions 43A and 43B are loosened to be temporarily fixed, and the door 15 is closed. The third screwing portion 43C is loosened to a temporary fixing state, and after adjusting the inclination of the door 15 using the elongated insertion holes 41A, 41B, 41C, the third screwing portion 43C is permanently fixed, Subsequently, the door can be opened and the first and second screwing portions 43A and 43B can be fastened to take a simple procedure.
[0018]
As described above, according to this embodiment, of the three screwing portions 43A, 43B, and 43C provided when the hinge plate 31 is attached, the inner two screwing portions 43A and 43B are closed. Since it is a structure hidden by the door 15 in the state, the hinge plate 31 cannot be removed in the closed state. Therefore, if the locking mechanism 20 is provided, it is possible to reliably prevent the door 15 from being unnecessarily opened regardless of the structure, and to ensure theft prevention.
[0019]
Since one screwing portion 43C of the three screwing portions 43A, 43B, and 43C is exposed to be operable from the front face in the closed state, for example, the side hidden by the door 15 in the closed state About screwing part 43A, 43B, at least one place is temporarily fixed in an open state, the screwing part 43C on the exposed side is fixed after the door 15 is closed, and the screwing part on the side hidden as an open state again It is possible to adopt an attachment method in which 43A and 43B are permanently fixed. Therefore, the door 15 can be attached in a substantially closed state, and position adjustment and the like can be performed easily and accurately.
[0020]
Further, with respect to the upper hinge plate 31, one part of the screwing portions 43 </ b> A and 43 </ b> B on the hidden side is temporarily fixed, and the hinge plate 31 is rotated upward from the normal posture around the screw plate, and the door 15 is moved downward. After being supported by the hinge plate 31, it is possible to perform an attachment procedure in which the upper hinge plate 31 is rotated toward the normal posture and the hinge pin 35 is fitted into the fitting hole 37. There is no need to insert / remove the upper fitting hole 37 to / from the hinge pin 35 while raising and lowering the door 15, and the door 15 can be attached and removed more easily.
