ABSTRACT:
The gasket of the invention is formed of a compressible gasket member, a ring member, and main and auxiliary grommets. The auxiliary grommet is installed around a hole of the gasket member, and the ring member is situated inside the auxiliary grommet. The main grommet is arranged to surround the auxiliary grommet and the ring member. When the gasket is tightened, surface pressure is formed on the ring member and the auxiliary grommet without concentrating at one portion. Thus, the area around the hole is effectively sealed without deforming the engine parts.
