       10 . The structure according to  claim 9 , further comprising:
 a fixing end provided at one side of the adjusting element; and   an elastic element interposed between the fixing end and the mount.   
   
   
       11 . The structure according to  claim 10 , wherein the elastic element is configured to be compressed while an end of the adjusting element is raised along the height adjusting path, and configured to be returned to its original state while the end of the adjusting element is moved forward along the fixing path. 
   
   
       12 . The structure according to  claim 9 , wherein front ends of the rail are bent toward each other in order to prevent the adjusting element from departing from the rail. 
   
   
       13 . The structure according to  claim 9 , wherein the adjusting element is provided at a lower side of the shelf and is bent in a shape the same as a side and front circumference of the shelf. 
   
   
       14 . The structure according to  claim 13 , wherein a push member is provided at a position of the adjusting element extending along a front circumference of the shelf. 
   
   
       15 . The structure according to  claim 14 , wherein the shelf is lowered for one time by the operation of pushing and releasing the push member. 
   
   
       16 . The structure according to  claim 9 , wherein the adjusting element configured to be forwardly moved after being retreated by the operation of lifting the shelf. 
   
   
       17 . A refrigerator having a structure for adjusting height of a shelf therefor, comprising:
 a body in which a refrigerating chamber or a freezing chamber is provided;   a rail which is provided at a rear wall of the refrigerating chamber or the freezing chamber;   a shelf which is movably connected to a front of the rail, and of which at a rear end a mount is extended;   an adjusting element which is provided at a lower portion of the shelf, and of which an end is received in the inner side of the rail to adjust height of the shelf by moving in a back-and-forth direction.   
   
   
       18 . The refrigerator according to  claim 17 , wherein a plurality of support elements which are composed of a slanted surface and a horizontal portion, and a plurality of guide elements protruded at a surface opposite to the support element are vertically arranged in the rail at regularly spaced intervals. 
   
   
       19 . The refrigerator according to  claim 18 , wherein each of the guide elements is disposed between the adjacent support elements. 
   
   
       20 . The refrigerator according to  claim 18 , wherein the adjusting element includes:
