    摘要： A monolithic catalyst converter includes a monolithic catalyst (2), and a catalyst container (1). The catalyst container includes a tube-shaped member (1), and a pair of funnel-shaped cone members (1d,1e). The tube-shaped member holds the monolithic catalyst therein, and have opposite ends. The funnel-shaped cone members are connected with exhaust pipes of an exhaust system, are disposed at the opposite ends of the tube-shaped member, and are formed free from welding and integrally with the tube-shaped member. The monolithic catalyst converter can be manufactured with a high material yield (or a low scrap rate), at a reduced cost and under a good working environment, because it can be manufactured without the conventional troublesome welding operation and leak-test inspection.

    摘要翻译： 整体式催化转化器包括整体式催化剂（2）和催化剂容器（1）。 催化剂容器包括管状部件（1）和一对漏斗形锥体部件（1d，1e）。 管状构件将整体式催化剂保持在其中，并具有相对端。 漏斗状的锥形部件与排气系统的排气管连接，设置在管状部件的相对端，并且与管状部件形成为无焊接，整体形成。 由于可以在没有常规麻烦的焊接操作和泄漏检查检查的情况下制造，所以可以以低成本和良好的工作环境，以高的材料产率（或低废料率）制造整体式催化转化器。
