A refrigerator including a cooling chamber in a main body, includes: a rack assembly installed inside the cooling chamber; and a rack assembly drawing unit for drawing/putting the rack assembly out of/into the cooling chamber. Accordingly, food containers put on a rack of a rack assembly can be easily and conveniently taken out or checked regardless their locations by constructing the rack assembly to be selectively drawn out of a cooling chamber. Also, by attaching a vibration preventing rubber material to an end of the rack assembly, the food container put on the rack is prevented from being dropped, and the vibration noise can be effectively prevented.
