ることを特徴とする副室式内燃焼機関の燃焼室。A sub-chamber nozzle is provided at the top of the piston to communicate the main combustion chamber defined by the piston, the cylinder, and the cylinder head with the sub-combustion chamber formed in the cylinder head. In a sub-chamber type internal combustion engine having a protrusion capable of penetrating into a chamber nozzle, the sub-chamber nozzle and the protrusion are aligned with the center line of the sub-combustion chamber and the cylinder. The angle αL between the cylinder centerline side ridgeline of the cut surface of the pre-chamber nozzle on a plane including the centerline of the cylinder and a plane perpendicular to the cylinder centerline, and the cylinder centerline side ridgeline of the protrusion on the plane. A combustion chamber for a pre-chamber internal combustion engine, characterized in that the relationship between the angle αR and a plane perpendicular to the cylinder centerline is such that αL>αR.
