摘要： PROBLEM TO BE SOLVED: To suppress or prevent clogging of three-way catalytic converter 6 provided in an exhaust emission control device 5 for gasoline engine and clogging of a rectification member 7. SOLUTION: This device includes a three-way catalytic converter 6 including large numbers of passages 6a ... in which exhaust gas circulates and a straightening member 7 arranged in an exhaust gas introduction side of the three-way catalytic converter 6 and straightening in-flow of exhaust gas to each passages 6a ... of the three-way catalytic converter 6 roughly in parallel to a center axial line of each passage 6a .... Metal chemical compound contained in exhaust gas is made not to easily adhere on the exhaust gas introduction part of the three-way catalytic converter 6 by rectification action of the rectification member 7. The rectification member 7 is displacably supported by a cylindrical exterior case 4 via a support member 9. Consequently, since the rectification member 7 is displaced (vibrated) via the support member 9 when vibration of the gasoline engine is transmitted to the exterior case 4, metal chemical compound contained in exhaust gas does not easily adhere to the exhaust gas introduction part of the rectification member 7.
