Metal gasket

Abstract

A metal gasket (10) installed between a cylinder head and a cylinder block comprises at least one metal substrate (11) coated with a sealant (19) on its outer surface, and including a full bead (13) for cylinder bore hole sealing and a half bead (16) for liquid hole sealing. The half bead (16) includes: an inclined plate portion (16b) connected to a flat substrate body (11a) of the metal substrate (11) through a first bend portion (16a) and inclined with respect to the substrate body (11a); and an edge plate portion (16d) connected to the inclined plate portion (16b) through a second bend portion (16c) and inclined with respect to the inclined plate portion (16b). A radius at a convex surface of the first bend portion (16a) and a radius at a concave surface of the second bend portion (16c) are in a range of 2.0 mm to 3.5 mm.
