摘要： 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.

摘要： A cylindrical body of a catalyst container has that overlapped portion of a rolled sheet of metal which is welded in an axial direction of the cylindrical body. A coned portion is welded, at a large diameter portion thereof, to each axial end of the cylindrical body. The large diameter portion of the coned portion has a flange which extends radially outward, and the axial end of the cylindrical body is brought into abutment with an outward end surface of the flange and is fillet-welded along an outer corner which is formed by the flange and the cylindrical body. A heat shield cover is mounted under the casing by connecting a second flange connected to a front end of a downstream exhaust gas pipe to a first flange connected to a rear end of the casing. The heat shield cover is made up of a mounting flange portion and a cover portion. The mounting flange portion is extended so as to abut with an upstream surface of a lower part of the first flange. The cover portion is bent backward and forward to cover the bottom surfaces of the rear coned portion and the first and second flanges. The heat shield cover is connected to the first and second flanges with bolts and nuts by inserting the bolts from the side of the mounting flange portion.
摘要翻译：催化剂容器的圆筒体具有沿圆筒体的轴向焊接的轧制金属板的重叠部分。锥形部分在其大直径部分处焊接到圆柱体的每个轴向端部。锥形部分的大直径部分具有径向向外延伸的凸缘，并且圆柱体的轴向端部与凸缘的外端表面邻接并且沿着外角形成圆角焊接，该外角由法兰和圆柱体。通过将连接到下游排气管的前端的第二凸缘连接到与壳体的后端连接的第一凸缘，将防护罩安装在壳体下方。隔热罩由安装凸缘部分和盖部分组成。安装凸缘部分延伸以与第一凸缘的下部的上游表面邻接。盖部分向后并向前弯曲以覆盖后圆锥形部分和第一和第二凸缘的底表面。通过从安装凸缘部分的侧面插入螺栓，隔热罩通过螺栓和螺母连接到第一和第二凸缘。
