PURPOSE: A sealing structure for an exhaust manifold is provided to reduce leakage of exhaust gas by reducing the pressure difference between the interior and exterior of the exhaust manifold. CONSTITUTION: A sealing structure comprises a first body(30) and a second body(40). The first body has a first groove(31) and a second groove(32) with stepped cross sections. The second body has a first protrusion(41) and a second protrusion(42) with stepped cross sections. The first body and the second body are coupled with each other. The inner surface of the first groove surface-contacts the outer surface of the first protrusion, and the inner surface of the second groove surface-contacts the outer surface of the second protrusion. A sealing(50) is fit to a sealing groove(43) formed at the outer surface of the second protrusion.
