A refrigerator is provided to reduce contact surfaces for a floor and preventing the re-arrangement of horizontality by mounting wheels to be foldable in the vertical direction for the contact or separation of the wheels and the ground. Wheel elements(20,30) are positioned via a bottom surface of a main body(10) for moving the main body, wherein the wheel elements are foldable in the vertical direction to contact the ground or not alternatively. Securing parts(21) are indented in the main body for receiving the wheel elements. The wheel elements are folded upward through rotation by hinge parts(13) connected to the main body. |
