HEAD GASKET HAVING DOUBLE HALF BEAD STRUCTURE OF WATER INLET SECTION

摘要

The present invention is to increase the air tightness of a gap, which is generated by the behaviors of a cylinder block and a cylinder head, by following characteristics which increase by double half beads, wherein the water inlet section of a head gasket is provided at the rim thereof with the double half beads having various inclination angles. The head gasket of the water inlet section surface-contacts the cylinder head at the upper portion of a metal plate and the cylinder block at the lower portion thereof. The head gasket includes: half beads formed with predetermined inclination surfaces along the rim of the water inlet section; and vanishing beads having inclination surfaces in the opposite direction of the half beads and formed in parallel with the half beads, wherein both ends of the vanishing beads encounter the rim, which is apart from the water inlet section by a predetermined distance, so as to vanish.
