PROBLEM TO BE SOLVED: To improve the durability of a gasket by suppressing the thermal influence of a fluid.SOLUTION: When high temperature exhaust gas passes through an exhaust path 2008 of a turbo charger 20 from an exhaust path 1808 of an exhaust manifold 18 through an opening 36, the heat of exhaust gas is transmitted from an inner peripheral part of the exhaust path 1808 of the exhaust manifold 18 toward an outer periphery, and transmitted from an inner peripheral part of the exhaust path 2008 of the turbo charger 20 toward an outer periphery. A first recessed portion 2602 and a second recessed portion 2802 are positioned at places of a multi-layer gasket 30 on the inside of a first bead portion 38. A first air layer 26 formed on the first recessed portion 2602, and a second air layer 28 formed on the second recessed portion 2802 have extremely low heat conductivity as compared with metallic material configuring the exhaust manifold 18 and the turbo charger 20.SELECTED DRAWING: Figure 5 |
