Exhaust gas control apparatus for internal combustion engine

An exhaust gas control apparatus comprising:

• a catalytic converter;
• and
• a merging portion that connects the catalytic converter and an internal combustion engine and that is provided with a dispersion surface on an inner wall of the merging portion, wherein
• the internal combustion engine including a plurality of cylinders and a plurality of exhaust passages respectively communicating with the cylinders,
• the merging portion has a cylindrical shape and is connected to a downstream side portion of each of the exhaust passages,
• the catalytic converter is connected to a downstream side of the merging portion, and
• the dispersion surface faces an outflow opening of exhaust gas in the downstream side portion and that three-dimensionally disperses a main flow of exhaust gas linearly flowed into the merging portion from the outflow opening.
