CONSTITUTION: A bypass channel(10) is installed in a case(1) to guide exhaust gas to pass a carrier(4) and detour so as to be discharged. The bypass channel is placed in the case, and directly connects an inlet(2) and an outlet(3) of the case so that some of exhaust gas introduced through the inlet is directly discharged through the outlet without passing the carrier. An opening and closing unit(11) is installed to an inlet of the bypass channel to be selectively opened and closed depending on strength of exhaust pressure, and comprises a valve body(12) and a spring(13). The valve body opens and closes the inlet of the bypass channel, and has one side hingedly coupled to a wall of the case to allow the valve body to rotate. The spring is formed on an axis of the valve body to elastically press the valve body in closing direction.
