Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To provide high sealability as well as a high vibration isolating function by arranging the first elastic member having relative hardness and small compression deformation on the bolted part of a core member, and the soft and highly conformable second elastic member on a fluid seal part other than the bolted part, and making the thickness of the second elastic member equal to or larger than the thickness of the first elastic member. SOLUTION: This composite gasket uses a metallic plate for a seal core member 1 having a bolt part 11 and a seal part 12, hard vulcanized rubber as the first elastic member at the position of the bolt part 11, and soft and highly conformable expanded rubber as the second elastic member at the position of the seal part 12, all integrated with one another. Furthermore, the thickness of the second elastic member is made equal to or larger than the thickness of the first elastic member. In this case, the first elastic member having hardness is laid at the bolt part 11 and a drop in torque at the bolt part 11 is restrained. At the same time, the contact of metals with each other is prevented, thereby providing effectiveness for isolating a vibration as well.  Also, the soft second elastic member is laid at the seal part 12 and a resonance point can be thereby shifted to a low-frequency zone via a small spring constant.
