Disclosed herein is an exhaust gas control device for internal combustion engines. The exhaust gas control device has a main exhaust pipe (3) communicating with an exhaust manifold (2) used for guiding exhaust gas discharged from a combustion chamber (1) of an engine, a catalytic converter (6) arranged on a predetermined position of the main exhaust pipe (3) for purifying unburnt fuel discharged with the exhaust has and having a plurality of sequentially arranged catalyst units (6a, 6b, 6c), and an unburnt fuel collection tank (8) provided with a plurality of cooling fins (9) and connected to the catalytic converter (6) through a branch pipe (7). The collection tank (8) collects purified unburnt fuel after the unburnt fuel is treated by the catalytic converter (6) so as to remove noxious materials therefrom.
