摘要： PROBLEM TO BE SOLVED: To improve, by a half bead 4c, followability to thermal deformation on a flange side to which a gasket 1 is attached, and to reduce a permanent set in fatigue by reducing an amount of plastic deformation compared to the case where a full bead is formed.SOLUTION: A gasket 1 comprises at least two seal plates, that is, a first seal plate 3 and a second seal plate 4 in which through holes 3a and 4a are provided, respectively. A grommet 6 is formed by folding back the circumference of the through hole of the first seal plate so as to surround the inner circumferential edge of the through hole of the second seal plate, and the inner diameter side of the grommet is formed as a pressure fluid hole 2 to be hermetically sealed. In the second seal plate 4, a half bead 4c protruding to the opposite side of the first seal plate 3 and surrounding the pressure fluid hole 2 is formed on the inner side of the grommet 6 and it is desirable to form a tip end 4d on the through hole 4a side of the half bead 4c as a half bead whose section is in the shape of a chevron by bending it toward the first seal plate side.
