When adjusting the displacement of the door 15 after use of the storage, the door 15 is opened and the first and second screwing portions 43A and 43B are loosened to temporarily fix the door 15, and the door 15 is closed. The third screwing portion 43C is loosened to temporarily fix the state, and the inclination and the like of the door 15 are adjusted using the elongated insertion holes 41A, 41B, and 41C, and then the third screwing portion 43C is fully fixed. Subsequently, the door can be opened and the first and second screwed portions 43A and 43B can be permanently fixed, so that it is possible to easily cope with the problem.
[0018]
As described above, according to the present embodiment, of the three screwing portions 43A, 43B, and 43C provided for attaching the hinge plate 31, two inner screwing portions 43A and 43B are closed. In this state, the hinge plate 31 cannot be removed in the closed state because the structure is hidden by the door 15. 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 thereof, and to ensure theft and the like.
[0019]
One of the three screwing portions 43A, 43B, and 43C is set so as to be operably exposed from the front in the closed state, so that, for example, the side that is hidden by the door 15 in the closed state. As for the screwing portions 43A and 43B, at least one portion is temporarily fixed in an open state, and after the door 15 is closed, the exposed screwing portion 43C is fixed, and the screwing portion on the side that is hidden again as the door is opened. An attachment method such as permanent fixing of 43A and 43B can be adopted. Therefore, the door 15 can be mounted with the door 15 substantially closed, and position adjustment and the like can be performed easily and accurately.
[0020]
Further, with respect to the upper hinge plate 31, one of the screwing portions 43A and 43B on the hidden side is temporarily fixed, and the hinge plate 31 is rotated upward from the normal posture around the center to release the door 15 and the door 15 is moved downward. After being supported by the hinge plate 31, the upper hinge plate 31 is turned toward the normal posture, and the mounting procedure of fitting the hinge pin 35 into the fitting hole 37 can be performed. It is not necessary to insert and remove the upper fitting hole 37 with the hinge pin 35 while raising and lowering the door 15, so that the work of attaching and removing the door 15 can be performed more easily.
