       9 . The elastic member as claimed in  claim 8 , wherein the hollow shape seating part comprises at least one ring shape groove provide at least one of either the inner circumferential surface or the outer circumferential surface.  
   
   
       10 . The elastic member as claimed in  claim 8 , further comprising an auxiliary supporter having a first end coupled with the hollow shape seating part and a second end extended toward a surface supporting the base, the auxiliary supporter preventing the elastic member from being excessively transformed.  
   
   
       11 . The elastic member as claimed in  claim 10 , wherein the second end of the auxiliary supporter provided to have a predetermined distance from a surface supporting the base.  
   
   
       12 . The elastic member as claimed in  claim 11 , wherein thickness of the lower base is thicker than that of the auxiliary supporter.  
   
   
       13 . A refrigerator, comprising: 
 a body of a refrigerator having a space for storing food;    a compressor provided in the body for compressing refrigerant;    an elastic member for supporting the compressor and absorbing vibration of the compressor, the elastic member comprising: 
 a compressor seating part having a hollow passing through in an axis direction and an axial direction supporting part for supporting compressive load of the compressor; and  
 a hollow shape base provided at a lower part of the compressor seating part, the hollow shape base supporting the compressor seating part and having an average radius different from that of the axial direction supporting part; and  
 a stand inserted into the hollow of the elastic member for fixing the elastic member.
