Claim:
1. A refrigerator comprising: a cabinet that defines an appearance of the refrigerator; a storage compartment defined in the cabinet and configured to store an object; a first guide hole located at a first inner wall of the storage compartment; a second guide hole located at a second inner wall of the storage compartment, the second inner wall of the storage compartment being opposite of the first inner wall of the storage compartment; a first rotating bar that includes a first rotating shaft fitted in the first guide hole, the first rotating bar being configured to rotate about the first rotating shaft; a second rotating bar that includes a second rotating shaft fitted in the second guide hole, the second rotating bar being configured to rotate about the second rotating shaft; and a shelf configured to support an object stored in the storage compartment, the shelf being rotatably supported by the first rotating bar and the second rotating bar and being adjustable in height based on rotation of the first rotating bar and the second rotating bar, a first elastic element disposed in the first guide hole and configured to provide a forward elastic force to the first rotating shaft; and a second elastic element disposed in the second guide hole and configured to provide a forward elastic force to the second rotating shaft, a first damper disposed in the first guide hole and configured to dampen forward and rearward movement of the first rotating shaft of the first rotating bar based on the first rotating shaft of the first rotating bar sliding in the first guide hole in the forward and rearward direction; and a second damper disposed in the second guide hole and configured to dampen forward and rearward movement of the second rotating shaft of the second rotating bar based on the second rotating shaft of the second rotating bar sliding in the second guide hole in the forward and rearward direction wherein the first guide hole has a first space that extends in a forward and rearward direction and that allows the first rotating shaft of the first rotating bar to slide in the first guide hole in the forward and rearward direction, wherein the second guide hole has a second space that extends in the forward and rearward direction and that allows the second rotating shaft of the second rotating bar to slide in the second guide hole in the forward and rearward direction, wherein the shelf is configured to slide in the forward and rearward direction based on the first rotating shaft of the first rotating bar sliding in the first guide hole with the second rotating shaft of the second rotating bar sliding in the second guide hole, and wherein, based on the shelf being rotated to an upward position, the first rotating shaft is biased forward by the forward elastic force of the first elastic element and the second rotating shaft is biased forward by the forward elastic force of the second elastic element.
