Document Type and Number:
WIPO Patent Application WO/2017/090702
Kind Code:
A1
Abstract:
Provided is a metal gasket that is sandwiched between a pair of housings, the metal gasket comprising: a straight section including a bolt hole; a bead section formed to rise up from the inner peripheral edge of the straight section toward one side of the gasket thickness direction; and a bent section formed to be bent from the outer peripheral edge of the straight section toward the other side of the gasket thickness direction. When the metal gasket is compressively sandwiched by the pair of housings, the bead section elastically deforms to decrease in height and the straight section also elastically deforms. At this time, the inner peripheral edge of the straight section contacts one of the housings, and the outer peripheral edge of the straight section contacts the other housing, and the bent section contacts the one of the housings. Further, a gasket installation discrimination projection is provided on the outer peripheral edge of the metal gasket, partially in the circumference of the outer peripheral edge of the bent section or the outer peripheral edge of the straight section.
