摘要

A refrigerator may include a cabinet defined with a storage chamber therein, and a shelf assembly mounted in the storage chamber provided with a vertically movable shelf. The shelf assembly includes a guide member mounted in the storage chamber while having guide slots inclinedly formed at side walls of the guide member. The shelf is supported by the guide member to be vertically movable. Guide protrusions are provided at opposite lateral ends of the shelf to protrude laterally and are supported by the guide slots in a state of being slidably engaged in the guide slots. The guide slots have bent upper ends forming upper seats to support the guide protrusions. Each upper seat is formed such that a straight vertical line extending downwards from a center of the upper seat passes through a center of a lower seat formed at the corresponding guide slot.
