         6 . The refrigerator of  claim 1 , wherein
 the elastic deformation portion is spaced from the first inner wall, and   the fastening portion protrudes toward the first inner wall from the elastic deformation portion to be in contact with the first inner wall.   
     
     
         7 . The refrigerator of  claim 6 , wherein
 the fastening portion includes a protrusion protruding from the elastic deformation portion toward the first inner wall, and a coupling hole on the protrusion and through which the fastening member is coupled.   
     
     
         8 . The refrigerator of  claim 6 , wherein
 the fastening portion includes:
 an extension portion extending from the elastic deformation portion toward the first inner wall, 
 a contact portion extending from one end of the extension portion toward the first inner wall parallel to the first inner wall and in contact with the first inner wall, and 
 a coupling hole through the contact portion and through which the fastening member is coupled. 
   
     
     
         9 . The refrigerator of  claim 1 , wherein
 the first inner wall includes a support portion protruding to support the support case, and   the support case further includes an elastic protrusion interfering with the support portion and configured to be elastically deformed while being pressed by the support portion.   
     
     
         10 . The refrigerator of  claim 9 , wherein
 the support case further includes a case body supported by the support portion, and   the case body includes an interference prevention hole facing the support portion and configured to prevent the case body from interfering with the elastic protrusion while the elastic protrusion is elastically deformed, and   the elastic protrusion extends from one end connected to the case body to another end positioned at an inner side from edges of the interference prevention hole.   
     
     
         11 . The refrigerator of  claim 1 , wherein
 the fastening portion is a first fastening portion,   the fastening member is a first fastening member configured to couple the first fastening portion to the first inner wall,   the elastic deformation portion is a first elastic deformation portion, and   the support case further includes:
 a second fastening portion, opposite to the first fastening portion, coupleable to the second inner wall by a second fastening member, and 
 a second elastic deformation portion, opposite to the first elastic deformation portion, configured to be elastically deformed to be moveable while being supported by the second fastening portion and the second fastening portion is pressed by the second inner wall. 
   
     
     
         12 . The refrigerator of  claim 1 , further comprising
 a water supply pipe configured to supply water to the ice tray,   wherein the support case includes
 a water supply opening provided in an upper portion of the support case, the upper portion positioned above the ice tray, and formed to allow water to flow into the ice tray through the water supply pipe, and
