 a storage; and   a drawer including:
 one or more rollers disposed at at least one side of the drawer, the rollers being configured to enable the drawer to move relative to the storage in a first direction, and 
 one or more accommodation portions that at least partially receive the rollers, respectively; and 
   one or more protruding ribs extending along an outer perimeter surface of the storage, at least part of the protruding ribs extending parallel with the first direction.   
     
     
         2 . The refrigerator of  claim 1 , wherein the one or more protruding ribs includes a plurality of protruding ribs, and
 wherein the plurality of protruding ribs are spaced apart from each other.   
     
     
         3 . The refrigerator of  claim 2 , wherein each of the rollers includes:
 a rolling element;   a roller cover configured to accommodate the rolling element and enable the rolling element to rotate; and   a latch disposed at a side surface of the roller cover and protruding outwards, and   wherein the storage includes a latching groove being configured to be coupled by the latch.   
     
     
         4 . The refrigerator of  claim 3 , wherein the plurality of protruding ribs includes a first protruding rib, at least a portion of the first protruding rib extending to overlap the latching groove. 
     
     
         5 . The refrigerator of  claim 3 , wherein the plurality of protruding ribs includes a first protruding rib, at least a portion of the first protruding rib being spaced apart from the latching groove and extending along a shape of the latching groove. 
     
     
         6 . The refrigerator of  claim 2 , wherein each of the rollers includes:
 a rolling element;   a roller cover configured to accommodate the rolling element and enable the rolling element to rotate;   an insertion hole disposed at a lower portion of the storage; and   support parts disposed at both side surfaces of the insertion hole and disposed at a side surface of the roller cover.   
     
     
         7 . The refrigerator of  claim 6 , wherein the plurality of protruding ribs includes a second protruding rib, at least a portion of the second protruding rib extending along the insertion hole and a shape of at least one of the support parts. 
     
     
         8 . The refrigerator of  claim 7 , wherein at least a portion of the at least one of the support part supports the lower portion of the storage. 
     
     
         9 . The refrigerator of  claim 7 , wherein at least a portion of the at least one of the support parts supports a lower portion of the second protruding rib. 
     
     
         10 . The refrigerator of  claim 4 , wherein a third protruding rib is spaced apart from the first protruding rib and is disposed above the first protruding rib. 
     
     
         11 . The refrigerator of  claim 1 , wherein the drawer includes:
 a body portion; and   a front surface portion disposed in front of the body portion,   wherein the front surface portion includes a side protrusion protruding outward of a side surface of the body portion,   wherein the storage includes a boundary surface defining a boundary between the side surface of the body portion and a rear surface of the side protrusion, and   wherein the boundary surface includes a curved surface.   
     
     
         12 . The refrigerator of  claim 11 , wherein a lowermost end of the boundary surface defines the boundary with the rear surface of the side protrusion and starts from an outermost surface of the side protrusion. 
     
     
         13 . The refrigerator of  claim 11 , wherein the protruding ribs protrude outward from the storage and do not extend beyond an outermost surface of the side protrusion. 
     
     
         14 . A refrigerator comprising:
 a storage; and   a drawer including:
 a roller disposed at a side of the drawer and configured to enable the drawer to horizontally move relative to the storage, and 
 an accommodation portion that at least partially receives the roller; and 
   a protruding rib extending along an outer perimeter surface of the storage and at least partially extending horizontally.   
     
     
         15 . The refrigerator of  claim 14 , wherein the protruding rib includes a plurality of protruding ribs, and
 wherein the plurality of protruding ribs are spaced apart from each other.   
     
     
         16 . The refrigerator of  claim 15 , wherein the roller includes:
 a rolling element;   a roller cover configured to accommodate the rolling element and enable the rolling element to rotate; and   a latch disposed at a side surface of the roller cover and protruding outwards, and   wherein the storage includes a latching groove being configured to be coupled by the latch.   
     
     
         17 . The refrigerator of  claim 16 , wherein the plurality of protruding ribs includes a first protruding rib, at least a portion of the first protruding rib extending to overlap the latching groove. 
     
     
         18 . The refrigerator of  claim 15 , wherein the roller includes:
 a rolling element;   a roller cover configured to accommodate the rolling element and enable the rolling element to rotate;   an insertion hole disposed at a lower portion of the storage; and   a support part disposed at a side surface of the insertion hole and disposed at a side surface of the roller cover.   
     
     
         19 . The refrigerator of  claim 18 , wherein the plurality of protruding ribs includes a second protruding rib, at least a portion of the second protruding rib extending along the insertion hole.
