The long holes 90a may be provided at least at two positions on the both ends of the presser fitting 90.

  In order to mount the displacement packing 9 formed in this way on the lower end portion of the door body 5, first, the mounting piece 92 of the displacement packing 9 is arranged at the lower end portion of the door body 5 and is pressed to the outside of the attachment piece 92. A metal fitting 90 is arranged. In this state, a cutter (not shown) is inserted into the long hole 90a of the presser fitting 90, and a cut 93 is made in the vertical direction at the approximate center of the mounting piece 92 in the long hole 90a. Then, the slipping packing 9 can be attached to the lower end portion of the door body 5 by passing the attachment screw 80 through the long hole 90a and the cut 93 and screwing it to the buried wood 57 embedded in the door body 5. .

  Here, the attachment aspect of the shift | offset | difference packing 9 according to the installation place of a slide door apparatus is demonstrated. As shown in FIG. 6A, when the gap S1 between the lower end of the door body 5 and the floor surface 8 is narrow, the shift packing 9 is shifted upward, and the mounting screw 80 is inserted into the long hole 90a and the cut 93 of the presser fitting 90. The lower end of the door body 5 is attached to the lower end of the door body 5 by screw connection. 6B, when the gap S2 between the lower end of the door 5 and the floor surface 8 is wide, the shift packing 9 is shifted downward, and the mounting screw 80 is inserted into the elongated hole 90a of the presser fitting 90. The screw packing 9 is mounted on the lower end portion of the door body 5 by being screwed and positioned above the cut 93. Further, as shown in FIG. 6C, when the floor surface 8 at the installation position of the sliding door device is inclined, the gaps S3 and S4 between the left and right lower portions of the door body 5 and the floor surface 8 are wide. Therefore, the displacement packing 9 is inclined along the inclination of the floor surface 8 and attached to the lower end portion of the door body 5. In this case, the shift packing 9 is formed by shifting the wide side of the gap S3 (left side in FIG. 6C) downward and the narrow side of the gap S4 (right side in FIG. 6C) upward. 8 can be attached to the lower end portion of the door body 5 along the inclination of 8. In this case, since the attachment piece 92 has flexibility, even when the shift packing 9 is attached to the door body 5 in an inclined state, the cut 93 absorbs the tilt of the shift packing 9 and shifts. The both ends of the packing 9 can be forcibly mounted without being inclined with respect to the door body 5.

  When the gap packing 9 is formed in this way, the gap S between the lower end of the door 5 and the floor 8 is wide, or the gaps between the left and right lower portions of the door 5 and the floor 8 are different. However, since the gap S between the lower end of the door body 5 and the floor surface 8 can be easily and reliably closed, the atmosphere in the cabinet 1 can be maintained.

  In addition, although the said embodiment demonstrated the case where the sliding door apparatus based on this invention was applied to the prefabricated refrigerator, it is the same also in general buildings other than a prefabricated refrigerator, for example, a clean room, a storage, a freezer, etc. Of course, it is applicable to.
