         2 . The ventilating apparatus of  claim 1 , further comprising a pre-filter installed in the other open side of the filter box. 
     
     
         3 . The ventilating apparatus of  claim 2 , wherein the rotary-type total heat exchange element has a flat disc shape. 
     
     
         4 . The ventilating apparatus of  claim 3 , wherein a section of the other open side of the first covering in contact with the rotary-type total heat exchange element has a semi-circular shape. 
     
     
         5 . The ventilating apparatus of  claim 1 , wherein the inside inlet is directed into one side of the body housing and the inside outlet is directed into the other side opposed to one side thereof. 
     
     
         6 . The ventilating apparatus of  claim 1 , further comprising a second covering disposed between an exhaust part of the second blower fan and the rotary-type total heat exchange element and preventing leakage of air flowing in the second air flow path,
 wherein the second air flow path is formed such that the air flowing therein sequentially passes through the outside inlet, the second blower fan, the second covering, the rotary-type total heat exchange element, and the inside outlet.   
     
     
         7 . The ventilating apparatus of  claim 6 , further comprising at least one purification filters disposed inside the second covering. 
     
     
         8 . The ventilating apparatus of  claim 1 , further comprising a shielding part encompassing a peripheral area of the rotary-type total heat exchange element. 
     
     
         9 . The ventilating apparatus of  claim 1 , further comprising an intake/exhaust duct including an intake duct having a first unit connected to the outside inlet and a second unit, and an exhaust duct having a first unit connected to the outside outlet and a second unit,
 wherein a combined part is formed by combining the first unit of the intake duct and the first unit of the exhaust duct, and a divided part is formed by dividing the second unit of the intake duct and the second unit of the exhaust duct from the combined part.   
     
     
         10 . The ventilating apparatus of  claim 9 , wherein the combined part has a cylinder shape. 
     
     
         11 . The ventilating apparatus of  claim 9 , wherein the combined part has the first unit of the intake duct and the first unit of the exhaust duct combined to have a cross-sectional yin-yang shape. 
     
     
         12 . The ventilating apparatus of  claim 9 , wherein the divided part has the second unit of the intake duct and the second unit of the exhaust duct directed in different directions. 
     
     
         13 . The ventilating apparatus of  claim 9 , further comprising a cover part covering the divided part;
 wherein parts of the cover part, corresponding to the second unit of the intake duct and the second unit of the exhaust duct, have nets or grill allowing for intake and discharge of air.   
     
     
         14 . The ventilating apparatus of  claim 9 , wherein the intake duct and the exhaust duct are formed of polyvinyl chloride (PVC). 
     
     
         15 . The ventilating apparatus of  claim 9 , wherein the first unit of the intake duct and the first unit of the exhaust duct are bonded with an adhesive.
