By pushing the movement of 0 in the + Z direction, the floating bearing 140 can be pushed and followed in the + Z direction so as to positively absorb the displacement H generated by the warped deformation portion 200 in FIG. 2B. . As a result, FIG.
In FIG. 2A and FIG. 2B, the upper end portion 7 of the first door 31.
With the axis 210 connecting 0 and the lower end portion 74 as the center, the lower end portion 71 exerts a force to push it down in the −Z direction. As a result, the displacement H of the deformed portion 200 due to the warp is
Is only in the + Z direction, and the upper end portion 70 of the first door 31
The inner end portion 50 including the lower end portion 71 can be positioned with respect to the inner end portion 60 of the second door 33 on the reference surface F of the door surface as shown in FIGS. 2 (A) and 2 (B). Therefore, a step defect in the front-rear direction near the joint between the inner end portions 50 and 60 does not occur, or the step defect can be prevented from occurring. Then, even if the amount of the displacement H of the deformed portion 200 due to the warp in FIG. 2B changes, the floating bearing 140 of FIG. 3 can move in the + Z direction and be absorbed so as to follow the displacement H.

Next, the case where the first door 31 is warped in the opposite W1 direction in FIGS. 2A and 2B will be described. In this case, the floating bearing 140 of FIG.
However, the upper end portion 73 of the first door 31 and the door shaft 110 move in the −Z direction, and the floating bearing 140 follows − this movement.
It moves in the Z direction against the force of the spring 143. That is, the upper end portion 73 is displaced in the −Z direction by pressing the spring 143. In this case, the position of the lower end portion 71 of the first door 31 is restricted in the −Z direction by the position holding portion 100 that is a door stopper, so that the reference surface F of the door surface shown in FIG.
The inner end portion 50 and the inner end portion 60 are kept at the position.

As shown in FIG. 5, since the guide portion 150 that functions as a self-weight fall prevention portion is provided for the upper outer frame portion 40, the door shaft 110 is fitted into the bearing 146 of the floating bearing 140. It is possible to prevent the floating bearing 140 from dropping or dropping from the recess 144 by its own weight before being assembled. by this,
It is possible to easily assemble the upper outer frame portion 40 and the door. As described above, in the storage structure having the double door of the present invention, it is possible to prevent a step defect in the front-rear direction (Z direction) near the joint between the two left and right doors. Even if the door warp amount or warp direction changes, the floating bearing 1
Since 40 can be appropriately moved in the Z direction by the action of the spring 143, it is possible to prevent a step from occurring near the joint between the inner end 50 of the first door and the inner end 60 of the second door.
In the double door structure of the present invention, it is possible to prevent a step difference in the front-rear direction near the joint between the two left and right doors. In particular, even if there is a change in the amount of warp or the direction of warp, correction is automatically performed within the set range, so it is possible to always prevent a step near the seam.

The present invention is not limited to the above embodiment. In the above-described embodiment, the storage structure is used as a base for mounting the electronic device, but the storage structure is not limited to this and may be normal storage furniture for storing the storage object.
