Claims

[Scope of utility model registration request]

In a ceramic chamber with a shrink-fitting metal ring, which forms a sub-combustion chamber by shrink-fitting a metal ring to the outer periphery and inserting it into a recess on the lower surface of the cylinder head, a ring-shaped groove is formed at the lower part of the outer periphery of the metal ring, and a ring-shaped groove is formed in the groove. 1. A ceramic chamber with a shrink-fit ring, characterized in that a ring having outward tension is closely fitted to the inner circumferential surface of the recess.
