Claims

[Scope of utility model registration request]

The gasket is made by laminating a plurality of thin metal plates, and an exhaust gas hole is bored in the middle of the gasket for the exhaust gas to pass through, and the inner peripheral end of the exhaust gas hole of the thin metal plate is A grommet is attached to the first thin metal plate located on the outermost surface of the thin metal plates, and extends in an annular shape around the exhaust gas hole and protrudes from both the front and back surfaces of the first thin metal plate. A first protrusion is provided, and a third thin metal plate, which is the third thin metal plate counted from the first thin metal plate, has a circle having a diameter smaller than that of the first protrusion concentrically with the first protrusion. a second protrusion forming a ring and protruding from both the front and back sides of the third thin metal plate; and a second protrusion forming a ring and protruding from both the front and back sides of the third thin metal plate; A third protrusion is provided,
A laminated gasket characterized in that a second thin metal plate having no protrusions is interposed between the first thin metal plate and the third thin metal plate.
