 a cushion portion including an inner surface and an outer surface to correspond to a corner of the washing machine to pack the washing machine; and   a recess indented from the outer surface of the cushion portion to have a cross sectional area gradually decreasing from the outer surface to the inner surface of the cushion portion.   
     
     
         2 . The corner protection pad according to  claim 1 , wherein:
 the cushion portion includes a first cushion portion having a first inner surface to come into close contact with one surface adjacent to the corner of the washing machine and a first outer surface at an opposite side of the first inner surface; and   the recess includes a first recess indented from the first outer surface to the first inner surface of the first cushion portion.   
     
     
         3 . The corner protection pad according to  claim 2 , wherein:
 the cushion portion further includes a second cushion portion having a second inner surface bent from the first inner surface by a predetermined angle to come into close contact with the other surface adjacent to the corner of the washing machine and a second outer surface at an opposite side of the second inner surface; and   the recess further includes a second recess indented from the second outer surface to the second inner surface of the second cushion portion.   
     
     
         4 . The corner protection pad according to  claim 1 , wherein the recess has an inwardly-tapered slope to disperse stress caused by external force. 
     
     
         5 . The corner protection pad according to  claim 1 , wherein the recess has at least one of a quadrangular pyramid shape and a circular cone shape. 
     
     
         6 . The corner protection pad according to  claim 1 , wherein a plurality of recesses is arranged in at least one of vertical and horizontal directions. 
     
     
         7 . The corner protection pad according to  claim 3 , wherein the first cushion portion and the second cushion portion are bent from each other such that an angle of an approximately 90 degrees is formed therebetween. 
     
     
         8 . The corner protection pad according to  claim 1 , further comprising protrusions protruding respectively from both ends of the cushion portion so as to be coupled into other protection pads for packing of the washing machine. 
     
     
         9 . The corner protection pad according to  claim 1 , wherein the cushion portion contains a shock-absorbing material including Styrofoam. 
     
     
         10 . A corner protection pad for packing of a washing machine, comprising:
 a cushion portion having a bent shape to correspond to a corner of the washing machine to pack the washing machine;   a recess indented in the cushion portion to absorb external force applied by a transportation device; and   an inwardly-tapered slope having a predetermined inclination to provide the recess with a gradually decreasing cross sectional area.   
     
     
         11 . A corner protection pad for packing of a washing machine, the corner protection pad comprising a cushion portion having a length corresponding to a corner of the washing machine to pack the washing machine,
 wherein the cushion portion includes first and second cushion portions bent from each other to come into close contact with both surfaces adjacent to the corner of the washing machine, and   wherein the first and second cushion portions respectively include first and second recesses having a cross sectional area gradually decreasing inward of the cushion portions.   
     
     
         12 . A washing machine packing structure comprising a corner protection pad, the corner protection pad including a cushion portion having a length corresponding to a corner of the washing machine to cover the corner of the washing machine,
 wherein the corner protection pad includes the cushion portion having a bent shape to come into close contact with the corner of the washing machine, and a recess having a cross sectional area gradually decreasing inward of the cushion portion.   
     
     
         13 . The washing machine packing structure according to  claim 12 , wherein:
 the cushion portion includes a first cushion portion having a first inner surface to come into close contact with a first frame surface adjacent to the corner of the washing machine and a first outer surface at an opposite side of the first inner surface; and   the recess includes a first recess indented in the first cushion portion.   
     
     
         14 . The washing machine packing structure according to  claim 13 , wherein:
 the cushion portion further includes a second cushion portion bent from the first cushion portion by a predetermined angle and having a second inner surface to come into close contact with a second frame surface adjacent to the corner of the washing machine and a second outer surface at an opposite side of the second inner surface; and   the recess further includes a second recess indented in the second cushion portion.   
     
     
         15 . The washing machine packing structure according to  claim 12 , further comprising an upper protection pad mounted on the washing machine to protect an upper portion of the washing machine, and a lower protection pad to protect a lower portion of the washing machine placed thereon. 
     
     
         16 . The washing machine packing structure according to  claim 15 , further comprising protrusions protruding respectively from both ends of the cushion portion so as to be coupled into the upper protection pad and the lower protection pad.
