         8 . The air conditioner of  claim 7 , wherein the coupling slot is elongated in a direction parallel to the flow direction of the air flow flowing through the discharge flow path. 
     
     
         9 . The air conditioner of  claim 8 , wherein the at least one communication hole comprises a plurality of communication holes disposed in a direction intersecting the flow direction of the air flow flowing through the discharge flow path, and wherein the coupling slot is disposed in a row with the plurality of communication holes. 
     
     
         10 . The air conditioner of  claim 5 , wherein the movable portion comprises a coupling pillar formed in the coupling slot, and wherein the link comprises a coupling recess configured to be coupled to the coupling pillar. 
     
     
         11 . The air conditioner of  claim 5 , wherein a thickness of the fixed portion is thicker than a thickness of the connecting portion. 
     
     
         12 . The air conditioner of  claim 6 , wherein the connecting portion is bent as the moving portion moves. 
     
     
         13 . The air conditioner of  claim 5 , wherein the connecting portion comprises:
 a first connecting portion that connects the movable portion to the fixed portion; and   a second connecting portion that extends from the movable portion toward the fixed portion and spaced apart from the fixed portion.   
     
     
         14 . The air conditioner of  claim 13 , wherein the connecting portion comprises a slit formed between the first connecting portion and the second connecting portion. 
     
     
         15 . The air conditioner of  claim 14 , wherein an edge of the second connecting portion facing the fixed portion is curved. 
     
     
         16 . An air conditioner, comprising:
 a case comprising an intake port and a discharge port;   a fan that is disposed inside of the case and forms an air flow;   an indoor heat exchanger that heat-exchanges air inside of the case with a refrigerant; and   a guide that is disposed downstream of the fan and guides the air flow flowing to the discharge port, wherein the guide comprises a plurality of vanes disposed in a row in a discharge flow path formed between the discharge port and the fan, wherein vanes disposed at outermost edges of the guide comprises at least one communication hole that extends therethrough.
