ABSTRACT:
This metal gasket is adapted to excellently seal a height different portion occurring on the opposed surfaces of a cylinder block and a chain case, by elastic members provided in recessed portions of full beads on an elastic metal plate. In this metal gasket, a first elastic metal plate is laminated on a second elastic metal plate so that the ridges of full beads on the first elastic metal plate contacts the second elastic metal plate. The first elastic metal plate is provided with a half bead extending along the circumference of an opening in which a camshaft driving chain travels, and full beads position in the regions which correspond to the opposed surfaces of a three-surface combining portion. In order to seal a height different portion occurring on the opposed surfaces of the three-surface combining portion, elastic members are provided in the recessed portions of the full beads formed on the first elastic metal plate, in such a manner that the elastic members are positioned in the three-surface combining portion.
