Abstract

A refrigerator includes a cabinet; a main door; a sub door rotatably connected to the main door; a main hinge device that allows the main door to rotate with respect to the cabinet; and a sub hinge device that allows the sub door to rotate relative to the main door. The main hinge device includes a hinge body installed at the cabinet, a pin unit provided at the hinge body or the main door, and a pin slot provided at the hinge body or the main door. The sub hinge device includes a hinge body coupled to the sub door, and a hinge pin extending from the hinge body and providing a rotation center of the sub door. During an opening process of the main door, relative positions of the pin slot and the pin unit vary, thereby allowing the rotation center of the main door to move.
