         3 . The device according to  claim 2 , wherein the shoelace connects the opposite sides of the opening in zigzags, is crossed between opposite lateral walls, and is provided with a first connecting member to which the first end part of the pull wire is locked in at least one intersection between the opposite lateral walls. 
     
     
         4 . The device according to  claim 3 , further comprising
 a handle connected to at least one among the shoelaces connecting the opposite sides of the opening; and   a hook provided in a rear of the shoe main body and holding the shoelace pulled using the handle.   
     
     
         5 . The device according to  claim 4 , wherein the hook is provided in plural and spaced in a lateral direction. 
     
     
         6 . The device according to  claim 4 , wherein the lateral wall is formed with through holes penetrating the lateral wall at a position where the shoelace connecting the opposite sides of the opening and the lateral wall are crossed. 
     
     
         7 . The device according to  claim 4 , wherein the lateral wall comprises through holes formed in upper and lower end parts and allowing the shoelace to pass therethrough, and the shoelace is not interfered with the lateral wall between the upper and lower end parts. 
     
     
         8 . The device according to  claim 4 , wherein the lateral wall comprises a shoelace support roller to freewheel in a portion for supporting the shoelace to which the first connecting member is connected. 
     
     
         9 . The device according to  claim 6 , wherein the first connecting member is connected to the shoelace crossed via lower through holes on the lateral wall. 
     
     
         10 . The device according to  claim 9 , wherein the tightening unit further comprises a second connecting member which is arranged in an upper region between opposite lateral walls, through which the shoelace crossed via an upper through holes of the lateral wall passes horizontally, and through which the pull wire passes vertically. 
     
     
         11 . The device according to  claim 10 , wherein the tightening unit further comprises a holding member installed on the pull wire placed in the second connecting member and the first connecting member and interfered in the second connecting member while pulling the pull wire. 
     
     
         12 . The device according to  claim 11 , wherein the tightening unit comprises a shoelace support roller to support the pull wire in a curved portion of the lateral wall bent along a curved surface of the tongue. 
     
     
         13 . The device according to  claim 12 , further comprising a stopper installed in an upper end part of the tongue and selectively holding the pull wire. 
     
     
         14 . The device according to  claim 13 , wherein the stopper is formed in front of a winding guide plate around which an exposed part of the pull wire is wound. 
     
     
         15 . The device according to  claim 14 , wherein the stoppers are spaced in an opposite direction at opposite sides and doubly hold the pull wire.
