Claims

[Scope of utility model registration request]

In a piston having a ceramic piston crown on the top surface, an explosive force receiving part that receives explosive force applied to the piston crown and a ring land part to which a piston ring is attached are separated, and the ring land part is A piston for an internal combustion engine, characterized in that the piston is thin-walled, and a cooling chamber is formed between the explosive force pressure receiving part and the ring land part, into which cooling lubricating oil is ejected.
