The present invention forms a double half bead at the T-joint section of a head gasket, so that not only following characteristics due to the behaviors of a cylinder block and a cylinder head increase via a gap generated by the double half beads, but also the filing effect of a liquid phase sealant increases by a space portion generated by the cylinder head or the cylinder block and upper and lower land surfaces, thereby increasing the air tightness of the T-joint section. The head gasket of the T-joint section, of which upper and lower metal plates are formed in the same shape to be correspondingly stacked, an upper portion surface-contacts the cylinder head, a lower portion surface-contacts the cylinder block, and one side end contacts a chain case, comprises: half beads formed with predetermined inclination surfaces along an inward direction-direction of a space portion in a chain case-edge from the one side end contacting the chain case; and extinction beads having inclination surfaces in the opposite direction of the half beads and formed in parallel with the half beads from the one side end contacting the chain case, wherein the other side end encounters an edge, which is apart from the T-joint section by a predetermined distance, so as to be extinct. |
