A refrigerator includes a cabinet with a first storage region sealable by a gasket of a door. A first hinge, outside a sealing region, allows the door to rotate relative to the cabinet. A second hinge, inside the sealing region, allows the door to rotate relative to a container having a second storage region that can be accommodated inside the first storage region. Rotating shafts of the first and second hinges are non-collinear, and a coupling between the container and the second hinge is drawn forward when the door rotates independent of the container. A guide unit protrudes into the first storage region and is selectively coupled to a fixing device at the container. The fixing device includes a push unit pushable by the door and a holder that fixes the guide unit as a rotation axis of the container, and releases the push unit from a pushed state.
