  • first gasket 410 and the second gasket 510 are connected by the extending member 520.
  • the configuration position of the second gasket 510 can be varied within a limitation of the length of the extending member 520 which may elongate.
  • the second gasket 510 when the pair of doors are closed, the second gasket 510 is tightly attached between the inner side wall of the door 200 and the side face of the sealing pillar 300, securing a gap to a degree.
  • the second gasket 510 when the pair of doors 200 are open, the second gasket 510 is tightly attached between the inner side wall of the door 200 and the side face of the sealing pillar 300, and in this state, the second gasket 510 may be stably released when certain elastic force is applied through the extending member 520, rather than being forcibly released.
  • a plurality of extending members 521 may be provided. Accordingly, the plurality of extending members 521 may connect the first gasket 410 and the second gasket 510 with elasticity of a certain level or higher, to thus prevent the second gasket 510 from wobbling and releasing from the end portions of the extending members 521. Namely, the fixing portion connecting the first gasket 410 and the second gasket 510 is increased, so the fixing force of the fixing portion connecting the first gasket 410 and the second gasket 510 can be increased.
  • a plurality of extending members 522 are provided, and hermetically sealed space (S) may be formed between the extending members 522.

  • the extending members 522 forming the multiple spaces (S) may air-tightly seal the space between the inner side wall of the door 200 and the side face of the sealing pillar 300 in a multiple manner, and insulate the multiple spaces (S) in a multiple manner against the outside. Accordingly, due condensation due to the difference in temperature with external air on the side face of the sealing pillar 300 can be effectively prevented.
  • the convex face 510b of the second gasket 510 as mentioned above has a certain curvature, so it can be effectively tightly attached correspondingly according to the shape of the side face of the sealing pillar 300 having a certain shape.
  • the partition 513 demarcating the first and second sub-air rooms 511 and 512 of the second gasket 510 is formed to be wavy to connect the convex face 510b and the support face 510a, and since the partition 513 is formed along a direction in which compressive force generated between the inner side wall of the door 200 and the side face of the sealing pillar 300 works, so the shape of the partition 513 can be easily deformed according to the size of the working compressive force to easily absorb the compressive force. Accordingly, although compressive force repeatedly acts on the wavy partition 513, damage to the second gasket 510, such that the second gasket 510 is ripped, or the like, can be effectively prevented.
  • the foregoing sub-air tight member 500 is connected to the main air-tight member 400 installed at a portion of the inner face of each of the doors 200.
  • the convex face 510b of the sub-air-tight member 500 installed at the side of the first door 210 to which the sealing pillar 300 is connected is tightly attached to the side face of the sealing pillar 300.
  • a gap may be formed between the convex face 510b of the second gasket 510 and the other side of the sealing pillar 300.

Accordingly, in consideration of a gap generated between the sealing pillar 300 and the free end of the first door 210, the second gasket 510 of the sub-air-tight member 500 may be disposed to be tightly attached to the side face of the sealing pillar 300 and the inner side wall of the first door 210.
  • a rib 320 may be formed to be externally provided with a certain length on one side face of the sealing pillar 300.
  • the rib 320 is protruded from one side face of the sealing pillar 300, and an end thereof may be tightly attached to the convex face 510b of the second gasket 510 of the sub-air-tight member 500 installed at the inner side of the first door 210 where the sealing pillar 300 is installed.
  • the rib 320 serves to additionally air-tightly seal a gap between the second gasket 510 and side face of the sealing pillar 300, and accordingly, cold air within the main body can be prevented from flowing out or external air can be prevented from being introduced into the main body through a space, if any, between the first door 210 and the sealing pillar 300, and a problem such as dew condensation formed on the side of the sealing pillar 300 and the inner side wall of the first door 210, or the like, can be solved.
  • a pair of ribs 320 and 321 may be formed to be protruded to extend with a certain length so as to be tightly attached to the convex face 510b of the second gasket 510 at both sides of the sealing pillar 300.
  • the respective second gasket 510 air-tightly sealing a gap between the both side faces of the sealing pillar 300 and the inner side wall of the door 200 can additionally block cold air through the pair of ribs 320 and 321.
  • the pair of ribs 320 and 321 may be made of the same material as that of the sealing pillar 300. Namely, the pair of ribs 320 and 321 may be configured as a solid without elasticity, and, among the pair of ribs 320 and 321, only the rib 321 at the side of the second door 220 where the sealing pillar 300 is not installed may be made of an elastic material.
  • the second gasket 510 at the side of the second door 220 where the sealing pillar 300 is not installed wobbles along the side face of the sealing pillar 300 when the second door 220 is opened or closed, and at this time, the rib 321 made of an elastic material can solve a problem such as damage due to frictional contact with the second gasket 510.
  • end portions of the ribs 320 and 321 have a certain curvature.
  • a gap may be formed between the opposite side of the rotation side of the sealing pillar 300 and the convex face 510b of the second gasket 510 at the side of the second door 220.
  • the first door 210 is disposed such that the sealing pillar 300 rotates, and the sealing pillar 300 is not installed at the second door 220.
  • the second gasket 510 installed at the inner side of the second door 220 is in frictional contact with the side of the sealing pillar 300 all the time so as to be damaged, so preferably, a certain gap is formed therebetween.
  • the outer face of the second gasket 510 slides in contact with the side of the sealing pillar 300, and in this case, since the convex face 510b of the second gasket 510 is formed to be convex, although the second gasket 510 slides in contact with the side face of the sealing pillar 300, frictional force generated between the side face of the sealing pillar 300 and the outer face of the second gasket 510 can be minimized.
