What is claimed is: 1. An obturator of a refrigerator having a refrigerator main body with an outer case and an inner case constituting an outer wall and an inner wall in the refrigerator, respectively, and a refrigerator door, which is opened and closed on the refrigerator main body and on which a
What is claimed is: 1. An obturator of a refrigerator having a refrigerator main body with an outer case and an inner case constituting an outer wall and an inner wall in the refrigerator, respectively, and a refrigerator door, which is opened and closed on the refrigerator main body and on which a door liner is provided opposite to the inner case, the obturator comprising: a door gasket for the refrigerator, wherein the door gasket includes a transformable and freely rotatable air bag that is configured to be mounted on one side of the refrigerator door of the refrigerator, wherein the air bag is configured to extend from a lateral portion of a sticking part to an inner face of the refrigerator door, where the airbag and the sticking part form one body, wherein the inner case includes a first surface corresponding to a surface contacting the outer case, and a second surface bent from the first surface, and wherein at least one portion of the air bag is configured to be accommodated in a predetermined gap defined between the second surface and the door liner of the refrigerator door so as to block up the predetermined gap. 2. The obturator of a refrigerator according to claim 1, wherein the air bag blocks up the predetermined gap between the second surface and the door liner when the refrigerator door is closed. 3. The obturator of a refrigerator according to claim 1, wherein an upper portion of the air bag is thin in a thickness of the air bag compared with a bottom of the air bag. 4. The obturator of a refrigerator according to claim 1, wherein a propping wall is equipped for maintaining a shape on an inner face of the air bag. 5. The obturator of a refrigerator according to claim 1, wherein a concave portion is formed for free transformation and rotation of the air bag on one side of a bottom of the air bag. 6. The obturator of a refrigerator according to claim 1, wherein a concave portion is formed for separation of the air bag from the sticking part on one side of an upper portion of the air bag. 7. An obturator of a refrigerator having a refrigerator main body with an outer case and an inner case, respectively, constituting an outer wall and an inner wall of the refrigerator main body, and a refrigerator door which is opened and closed on the refrigerator and which has a door liner provided on a mullion part to oppose the inner case, the inner case and the door liner defining a space, the obturator comprising: a door gasket, comprising: a first air bag; and a second air bag, wherein the second air bag is positioned laterally of the first air bag, wherein the inner case includes a first surface corresponding to a surface contacting the outer case, and a second surface bent from the first surface, and wherein the first air bag is configured to contact only the outer case of the refrigerator main body while the second air bag is configured to contact only the second surface when accommodated in the space, wherein a concave portion is formed on one side of the second air bag which faces the door liner, and wherein only an upper part of the concave portion of the second airbag is accommodated in the space. 8. The obturator of claim 7, further comprising a sticking part attached to the first air bag so that the sticking part sticks to only the outer case. 9. The obturator of claim 7, wherein the portion of the bag with the concave portion is thicker than the portion of the bag without the concave portion. 10. An obturator of a refrigerator having a refrigerator main body with an outer case and an inner case, respectively, constituting an outer wall and an inner wall of the refrigerator main body, and a refrigerator door having a door liner on a mullion part opposing the inner case, the inner case and the door liner defining a space, the obturator comprising: a first air bag; and a second air bag, wherein the first and second air bags are formed as one body, wherein the inner case includes a first surface corresponding to a surface contacting the outer case, and a second surface bent from the first surface, and wherein a concave portion is formed on one side of the second air bag which faces the door liner, and wherein only an upper part of the concave portion of the second air bag is seated in the space defined between the second surface and the door liner to block the space. 11. The obturator of claim 10, further comprising a sticking part attached to the first air bag so that the sticking part sticks to only the outer case. 12. The obturator of claim 10, wherein a portion of the bag with the concave portion is thicker than a portion of the bag without the concave portion.
