摘要： A reduction catalyst is disposed in an exhaust passage of an engine. A reducing agent added to the exhaust gas is urged to react with NOx in the exhaust gas, catalyzed by the reduction catalyst. A member for distributing the exhaust gas to which the reducing agent has been added is provided. This member is formed by applying of an axial welding and is disposed in the exhaust passage such that the internal surface of its joining portion is disposed to overhang from the topmost position of the joining portion.
