    Abstract: Provided is a refrigerator having a supporting frame whose installation structure is enhanced. The refrigerator includes an inner case defining a storeroom and having a projection formed to protrude to the inside of the storeroom, a drawer arranged to be inserted or pulled out from the storeroom, and a supporting frame arranged in the storeroom to guide movements of the drawer, and installed at the projection, wherein the supporting frame includes a fixer arranged on a side of the supporting frame to prevent the supporting frame from deviating from the projection, the fixer being deformed when pressurized by the projection and restored to an original state when the pressure from the projection is released.
