Abstract: A refrigerator includes a main body having a storage compartment, first and second doors opening or closing the storage compartment, and a pillar configured to block cool air from leaking between the first and second doors. The refrigerator also includes a hinge that rotatably connects the pillar to the first door and a holder disposed on the storage compartment and configured to guide rotation of the pillar. The hinge includes a rotation shaft that enables the pillar to rotate with respect to the first door and a rotation restriction unit that is configured to contact the holder and, based on the contact with the holder, move the rotation shaft in a direction parallel to an extension direction of the rotation shaft. The rotation restriction unit selectively restricts the rotation of the pillar with respect to the first door.

Abstract: In a guide rail attaching structure for a sliding door and a refrigerator using the same, the structure includes a support member coupled to an inner plate of a door of a refrigerator main body and having support coupling portions, and a pair of guide rails each having a guide rail coupling portion coupled to the corresponding support coupling portion, and slidable with respect to the refrigerator main body, wherein the support coupling portion and the corresponding guide rail coupling portion are coupled to each other by a hinge, whereby a force applied to the guide rail can be minimized to prevent warping of the guide rail even if the sliding door is open in any direction.

Abstract: A refrigerator is provided. The refrigerator may include an opening device which facilitates the opening of a door of the refrigerator. The opening device may be linked to a handle provided on an exterior surface of the door. The opening device may be installed within the door and protrude rearward, and may be linked to the handle such that manipulation of the handle initiates operation of the opening device to space the door apart from a cabinet of the refrigerator.
