ル排気系用触媒コンバータ。 A dual system in which the end face of a catalyst carrier carrying a catalyst is held in a case via a retainer, and the exhaust gas passage in the catalytic converter is divided into two by partition walls provided on the upstream and downstream sides of the catalyst carrier. In the exhaust system catalytic converter, the case has a structure that can be divided into two parts in a direction perpendicular to the flow direction of exhaust gas, and each divided case has a first partition wall that partitions an exhaust gas passage, and a first partition wall that partitions an exhaust gas passage. forming a groove extending along the partition wall of the case and forming a holding portion for holding the retainer; forming a second partition wall extending along the first partition wall of each case in the retainer; The outer peripheral part of the partition wall is
A catalytic converter for a dual exhaust system, characterized in that it fits into a groove in a partition wall.
