         3 . The aerosol-generating device according to  claim 1 , wherein the first gasket comprises:
 a first compressed portion interposed between the first inner wall of the upper housing and the second inner wall of the lower housing; and   a first extension portion extending from the first compressed portion along an outer side of the second inner wall of the lower housing, wherein the first extension portion is between the first inner wall of the upper housing and the second inner wall of the lower housing.   
     
     
         4 . The aerosol-generating device according to  claim 3 , wherein the first inner wall of the upper housing comprises a compression protrusion protruding from the first inner wall of the upper housing, and
 wherein the first compressed portion is interposed between the compression protrusion and the second inner wall of the lower housing.   
     
     
         5 . The aerosol-generating device according to  claim 4 , wherein the compression protrusion extends to cover an inner circumference of the first compressed portion of the first gasket, wherein the compression protrusion is in contact with the second inner wall of the lower housing. 
     
     
         6 . The aerosol-generating device according to  claim 4 , wherein the upper housing further comprises a support rib located adjacent to an upper end of the insertion space and protruding from the first inner wall of the upper housing to the insertion space. 
     
     
         7 . The aerosol-generating device according to  claim 6 , wherein the support rib is among a plurality of support ribs, wherein the plurality of support ribs are sequentially arranged along an inner circumference of the first inner wall of the upper housing and connected to each other to form a polygonal shape. 
     
     
         8 . The aerosol-generating device according to  claim 6 , wherein the first inner wall of the upper housing further comprises a stopper disposed between the support rib and the compression protrusion, wherein the stopper is located adjacent to the compression protrusion. 
     
     
         9 . The aerosol-generating device according to  claim 8 , wherein the first inner wall of the upper housing comprises a cross-sectional area formed to gradually decrease from the support rib toward the stopper. 
     
     
         10 . The aerosol-generating device according to  claim 2 , wherein the second outer wall of the lower housing comprises a flange angled from an end portion of the second outer wall of the lower housing toward an outside of the lower housing, wherein the end portion is adjacent to the first outer wall, wherein the flange is coupled to the first outer wall of the upper housing, and
 wherein the first outer wall of the upper housing comprises a stepped portion formed on an inner side thereof and coupled to the flange.   
     
     
         11 . The aerosol-generating device according to  claim 10 , wherein the second gasket comprises:
 a second compressed portion interposed between the flange and the base; and   a second extension portion interposed between the base and the first outer wall.   
     
     
         12 . The aerosol-generating device according to  claim 1 , wherein the second inner wall of the lower housing comprises a notch recessed in a longitudinal direction of the upper housing,
 wherein the wick is disposed inside the notch.
