Title:
金属製ガスケット
Document Type and Number:
Japanese Patent JP3747120
Kind Code:
B2
Abstract:
This metal gasket comprises a pair of beaded metal plates formed of elastic metal plates having beads extending along the circumferences of bore holes, and adapted to seal bore seal portions, and one outer circumferential metal plate formed of an elastic metal plate adapted to seal outer circumferential seal portions other than the bore seal portions. The beaded metal plates and outer circumferential metal plate have different sealing performance, and are adapted to seal the bore seal portions and outer circumferential seal portions respectively, these two types of metal plates being formed out of different materials, whereby the gasket manufacturing cost is reduced. A pair of beaded metal plates are provided with beads extending along the circumferences of the bore holes with the projecting portions thereof opposed to each other. Since the thickness of the single outer circumferential metal plate is set larger than that of each of the beaded metal plate and smaller than a total thickness of the two beaded metal plates, the surface pressure of the bore hole-surrounding regions can be set high.
