         2 . The sealing structure of  claim 1 , wherein the cover further comprises:
 a first end portion;   a second end portion opposite to the first end portion; and   an extension extending along the second lid face between the first end portion and the second end portion.   
     
     
         3 . The sealing structure of  claim 2 , wherein the extension is configured to deform based on the first end portion. 
     
     
         4 . The sealing structure of  claim 2 , wherein the cover further comprises a seat connected to the second end portion and configured to contact the second lid face. 
     
     
         5 . The sealing structure of  claim 4 , wherein the second lid face and the seat are separated from each other by a gap therebetween. 
     
     
         6 . The sealing structure of  claim 4 , wherein the second lid face and the seat are configured to be in contact with each other, and
 wherein the second lid face and the seat are not physically restrained to each other.   
     
     
         7 . The sealing structure of  claim 4 , wherein the cover further comprises an adhesive portion provided between the second lid face and the seat, the adhesive portion being configured to bond the second lid face and the seat. 
     
     
         8 . The sealing structure of  claim 1 , wherein the connector is positioned between the second lid face and the first cover face and the connector has a thickness smaller than the second distance between the first cover face and the second cover face. 
     
     
         9 . The sealing structure of  claim 1 , further comprising:
 a protrusion protruding from the second lid face or the connector.   
     
     
         10 . The sealing structure of  claim 1 , wherein the cover further comprises a coating layer provided on the first cover face. 
     
     
         11 . The sealing structure of  claim 1 , wherein the connector comprises:
 a support structure provided on the second lid face; and   an elastic body connected to the support structure and the second cover face.   
     
     
         12 . The sealing structure of  claim 11 , wherein the support structure comprises:
 a wall portion extending from the second lid face in a first direction; and   a base portion extending from the wall portion in a second direction intersecting with the first direction to be connected to the elastic body.   
     
     
         13 . The sealing structure of  claim 1 , wherein the connector comprises a support structure provided on the second lid face, the support structure having a pivot to which the cover is rotatably connected. 
     
     
         14 . The sealing structure of  claim 13 , wherein the cover further comprises:
 a first end portion;   a second end portion opposite to the first end portion;   an extension extending along the second lid face between the first end portion and the second end portion to be connected to the pivot; and   a weight provided on the extension.   
     
     
         15 . A sealing structure comprising:
 a lid comprising a first lid face, a second lid face opposite to the first lid face, a fragile area between the first lid face and the second lid face, and a first pole element provided in the fragile area and configured to exhibit a first polarity; and   a cover comprising a first cover face connected to the second lid face, a second cover face opposite to the first cover face, and a second pole element configured to exhibit a second polarity opposite to the first polarity,   wherein the first cover face faces the second lid face and overlaps the fragile area.   
     
     
         16 . The sealing structure of  claim 15 , wherein the lid and the cover are formed of substantially a same material. 
     
     
         17 . The sealing structure of  claim 15 , wherein the lid is formed of a first material and the cover is formed of a second material different from the first material. 
     
     
         18 . The sealing structure of  claim 15 , wherein the cover further comprises:
 a first end portion connected to the second lid face;   a second end portion opposite to the first end portion; and   an extension extending along the second lid face between the first end portion and the second end portion, and configured to deform based on the first end portion.   
     
     
         19 . A sealing structure comprising:
 a lid comprising:   a first lid face;   a second lid face opposite to the first lid face;   a fragile area between the first lid face and the second lid face; and   a plurality of guides provided in the fragile area, wherein a pair of adjacent guides from among the plurality of guides form a channel.   
     
     
         20 . The sealing structure of  claim 19 , wherein the lid is configured to elastically deform to have a first shape in which the plurality of guides contract and a second shape in which the plurality of guides expand.
