Claims

[Scope of utility model registration request]

It connects to the exhaust hole outlet of the cylinder head of a multi-cylinder engine and forms an exhaust pipe section that collects combustion exhaust gas from each cylinder, and also separates the exhaust pipe section into a plurality of parts, which are fitted together and connected to each other. In the joint structure of the exhaust manifold, a sealing member having heat resistance, oxidation resistance, and a low coefficient of thermal expansion is fitted into the space around the outer periphery of the exhaust pipe portions adjacent to each other, and a sealing member having a low coefficient of thermal expansion is fitted over the entire outer periphery of the sealing member. A configuration in which a presser ring is fitted into the abutting ring, a plurality of springs are disposed in the flange of the presser ring in the longitudinal direction of the exhaust pipe section, and the presser ring is provided so as to be slidable in the longitudinal direction of the exhaust pipe section. An engine exhaust manifold joint structure characterized by:
