に当接させたことを特徴とする触媒コンバータ。 A catalyst carrier is housed in a container into which exhaust gas flows, and a cylindrical part located inside the container and surrounding the outer circumferential surface of the catalyst carrier is provided on both sides of the catalyst carrier, and a cylindrical part that extends inward from one end of the cylindrical part. In the catalytic converter, at least one of the cap members is disposed, and the annular portions restrict movement of the catalyst carrier in the axial direction within the container. An inner groove of a foam sealing material having a cylindrical U-shaped cross section is fitted onto the cylindrical portion of the member, and the inner peripheral surface of the foaming seal material is brought into contact with the outer peripheral surface of the catalyst carrier. A catalytic converter characterized in that the outer peripheral surface of a foamable sealing material is brought into contact with the inner peripheral surface of a container.
