Abstract
A gasket resistant to vibration and noise generation is interposed between a cylinder head and an exhaust manifold of an engine. The gasket includes a gasket main body interposed between a cylinder head and an exhaust manifold of an engine, a base plate affixed to the gasket main body and having a heat shielding portion integral with a base portion and extending to a side of the exhaust manifold, and a reinforcement plate fixed to the heat shielding portion, in which the reinforcement plate is not present at a region of the base portion in contact with the gasket main body, and a reinforcement rib is formed at the region of the base portion in contact with the reinforcement plate and a region of the heat shielding portion in contact with the reinforcement. The base portion is provided with a projected portion projected into a path of introducing secondary air from a side wall of the cylinder head to an exhaust port.
