    • In an exhaust converter, where a casing is made by fastening and welding a cylindrical metal plate wrapped on an outer periphery of a supporting mat that is wrapped on an outer peripheral surface of a catalyst carrier, recovering means is formed at either or both of the supporting mat and the casing for recovering positional shifts of the supporting mat, thereby preventing positional shifts of the supporting mat in conjunction with fastening work of the metal plate from occurring. Such recovering means can be structured by a recess formed at an end of the casing, plural spaces formed of a crank shaped supporting mat, or a space formed at an overlapped portion at which each end of the casing is overlapped to each other.
    • 在排气转换器中,通过紧固和焊接包裹在包裹在催化剂载体的外周表面上的支撑垫的外周上的圆柱形金属板来制造壳体,在其中的一个或两个处形成回收装置 支撑垫和用于恢复支撑垫的位置偏移的壳体,从而防止支撑垫的位置偏移与金属板的紧固工作一起发生。 这种恢复装置可以由形成在壳体的端部处的凹部,由曲柄形支撑垫形成的多个空间或形成在壳体的每个端部彼此重叠的重叠部分处的空间构成。
