INTAKE MANIFOLD GASKET

PROBLEM TO BE SOLVED: To provide an intake manifold gasket free from oxidation or corrosion caused by gaseous mixture, water, oil or the like, which can be reduced in weight, worked easily, and readily fitted with a seal ring. SOLUTION: The intake manifold gasket 1 is arranged at a joint portion between a cylinder head and an intake manifold. The intake manifold gasket 1 includes a synthetic resin main body plate 2 having opening portions 22 corresponding to fluid flow holes 4 formed in the cylinder head and the intake manifold, and the elastic seal ring attached to each opening portion 22 along the inner periphery 23. A plurality of inwardly-projecting upper and lower engagement pawls 21 are formed at an upper corner portion 2A and a lower corner portion 2B of the inner periphery 23 of the opening portion 22 in such a manner that the plurality of upper and lower engagement pawls 21 do not overlap with one another as viewed from above. The outer periphery of the elastic seal ring 3 is held between the upper and lower engagement pawls 21 so that the seal ring 3 is engaged with the inner periphery 23 of the opening portion 22.
