3 and 114 and a center wall 116, and between the front wall 113 and the center wall 116 and between the center wall 116 and the rear wall 114, there are front and rear track bodies 117 and 118 crossing left and right, respectively.
Is attached. Each of the track bodies 117 and 118 is formed of a steel plate having a substantially U-shaped shape with a downward section, and the front track body 117 gradually lowers, for example, to the right and the rear track body 118 to the left. It is inclined. Then, the horizontal and flat upper surface 117 of each track body 117, 118
A and 118A are provided with two front and rear tracks 121 and 122, respectively.

くなる。As described above, the conventional door device 101 has the upper surfaces 117A, 1
Since the trajectories 121 and 122 formed in 18A are horizontal flat surfaces, the roller 126 moves forward and backward on the trajectories 121 and 122. Therefore, the doors 104 and 106
Is not determined at the center of each of the tracks 121 and 122 in the front-rear direction. When the door body 104 moves forward and the door body 106 moves backward, the sealing members 131 do not contact each other. The seal is not formed between the door bodies 104 and 106 and between the door bodies 104 and 106 and the rail frame.

った。That is, as described above, the front and rear doors 104, 10
6 are formed to facilitate their movement, so that when the doors 104 and 106 are closed, the sealing material 131 is used as the sealing material 1 of the facing doors 106 and 104.
31 and a gap is left between them and between the center walls 116, so that the inside cool air flows out from the gap and the outside air enters, so that the cooling capacity is reduced,
Frost formation and condensation also increase. Also, the track body 11
Since the number of bendings of the wires 7 and 118 themselves is small, the strength is weak, and there is also a problem that dents are generated due to vibrations during transportation.

118 is substantially M-shaped in cross section, and each track body 117,
In some cases, two front and rear tracks 121 and 122 are formed in the valleys of the M-shaped upper surfaces 117A and 118A. According to such a configuration, the orbits 121 and 122 become the orbit bodies 117 and 1
Since the rollers 126 are formed in the valleys at the center of the upper surfaces 117A and 118A of the roller 18, the rollers 126 fall into the tracks 121 and 122 and move.
Stabilizes in the center of 22. Further, the bending of the upper surface also increases the strength of the track bodies 117 and 118 themselves.

自体が重くなるという問題が発生する。However, since the corners of the rollers 126 move against the inclined portions of the upper surfaces 117A and 118A of the track bodies 117 and 118 (FIG. 11),
The durability is reduced, for example, only the corners of the rollers 126 are worn.
6 slidably abuts the roller 126, and the degree of freedom of movement of the roller 126 is lost, so that a problem arises in that the opening and closing of the doors 104 and 106 becomes heavy.

Therefore, when the doors 4 and 6 are closed, the sealing material 31 in the portion where the sash 23 overlaps surely comes into contact with each other, and the sealing material 31 in the other portions is the central wall 9, 16 of each rail frame 2, 3. Therefore, the sealability between the doors 4 and 6 and between the doors 4 and 6 and the rail frames 2 and 3 by the sealing material 31 is ensured.

It is much higher than the one that is cut at a degree and butt. Therefore, when the doors 4 and 6 move in the left-right direction due to opening and closing, the vertical side 31
The disadvantage that the upper and lower ends of B are turned up is also avoided. In particular, since the left and right ends of the horizontal side 31A are formed to abut from the upper and lower ends of the vertical side 31B, the left and right sides of the horizontal side 31A extending in the moving direction of the doors 4, 6 are formed. The vertical side 31B protects the end, and the horizontal side 3B
1A becomes hard to turn over.
