Abstract
A refrigerator may include a main door pivotably mounted to the cabinet to allow access to a storage compartment, the main door having an opening for an auxiliary storage compartment; a sub door pivotably mounted to the main door; a support shelf having at least one rotating shaft pivotably mounted at a lower vicinity of the opening; a case mounted in a recess formed in the main door, the case having an opening through which a slider slides, and a rotating gear provided with a pinion and coupled to the at least one rotating shaft. The slider includes a rack engaged with the pinion such that a movement of the sub door to close the auxiliary compartment rotates the support shelf to a vertical position, and a movement of the sub door to open the auxiliary compartment rotates the support shelf to a horizontal position.
