室封止装置。[Scope of Claim for Utility Model Registration] In a combustion chamber sealing device using a metal head gasket for an engine, which is constructed by fixing a cylinder head 4 on a cylinder block 1 of an engine with a metal head gasket 9 interposed therebetween, the gasket of the metal head gasket 9 Main body 1
A cylinder chamber hole 11 is made in 0, the circumferential wall 11a of the cylinder chamber hole 11 is rolled downward, and the core material 12 is rolled into the rolled wall 11a to form a rolled seal part 13. The core material 12 is made of a metal material with higher pressure resistance and coefficient of thermal expansion than the gasket body 10, and the cylinder liner 2 is fitted into the cylinder block 1 so that the upper end 2a of the cylinder liner 2 is lower than the upper surface of the cylinder block 1. Gasket body 1
The seal part accommodating part 14 is formed in a step-like manner in the part surrounding the cylinder liner 2 on the upper surface of the cylinder block 1, so that the seal part 13 of the head gasket 9 is inserted into the cylinder liner 2.
A combustion chamber sealing device using a metal head gasket for an engine, characterized in that the outer side of the protruding upper end portion 2a of the combustion chamber sealing device is fitted into a seal portion accommodating portion 14 of a cylinder block 1.
