Abstract
In an exhaust gas control apparatus for an internal combustion engine in which a catalytic converter is attached to an engine having a plurality of cylinders and a plurality of exhaust passages communicating with the plurality of cylinders, a diffusion portion that promotes a jet flow of a main flow of the exhaust gas flowing into the merging portion is provided at a merging portion connected to a downstream side of the exhaust passage. Further, on the inner wall of the merging portion facing the inlet of the exhaust gas provided in the exhaust passage, a dispersion face for three-dimensionally dispersing the main flow of the exhaust gas flowing linearly into the merging portion from the inlet is formed.
