Abstract
To a housing having a valve opening which serves as a bypass passage for exhaust gases, there is fixed one end portion of a plate valve which is capable of elastic deformation by deflection. The housing is provided with an enclosing wall which projects in a direction of opening of the plate valve in a manner to enclose the plate valve. A valve opening is formed by an inner peripheral space of the enclosing wall. When the exhaust gas pressure exceeds a predetermined pressure, the plate valve is deformed to a position beyond the open end of the enclosing wall, whereby the valve opening is opened to passage. A plate spring to contact the plate valve is provided. With an increase in the amount of deflection in the opening direction, the position of contact of the plate spring deviates toward a fixing end of the plate valve. The bending moment to be applied to the plate valve in a closing direction decreases.
