Claims

[Scope of utility model registration request]

A piston for a reciprocating internal combustion engine that has one oil ring and at least one pressure ring on the outer periphery, and the pressure ring located closest to the piston head is the outer circumferential surface of one joint end and the combustion chamber side. A recess that is open to the side surface, the outer circumferential surface, and the abutment end surface is provided at a corner close to the side surface facing the side, and the other end of the abutment has a recess located at a position opposite to the recess in the attached state. The reciprocating device is characterized in that the pressure ring has a convex portion that is accommodated and seated in the concave portion, and an inner cut is provided at a corner of the inner circumferential surface of the pressure ring and the side surface facing the combustion chamber side. Pistons for dynamic internal combustion engines.
