Claims (1)

[Claims for Utility Model Registration] (1) A pair of shell members are brought together midway to form a cylindrical container that accommodates a trap body for collecting particulate therein, and a trap body is formed on each of the shell members. Exhaust gas treatment for a diesel engine, in which the connecting portions protruding outward from the cylindrical container are welded together in contact with each other, and vertecumulate is removed from the exhaust gas flowing within the cylindrical container. In the device, an insertion hole is formed in the mating portion where the connecting portions abut each other, and a reinforcing member is inserted through the insertion hole, and both ends of the reinforcing member are attached to the connecting portion, respectively. An exhaust gas treatment device for a diesel engine characterized by being welded. (2) A pair of shell members are brought together in the middle to form a cylindrical container in which a trap body for collecting particulate is housed, and a cylindrical container is formed on each of the shell members and arranged on the outside of the cylindrical container. In an exhaust gas treatment device for a diesel engine that removes particulates from exhaust gas flowing in the cylindrical container, the connecting parts are welded together in contact with each other, and the connecting parts are in contact with each other and are welded together. 1. An exhaust gas treatment device for a diesel engine, characterized in that the contacting mating portions are clamped by clamping members, and the clamping members are welded to the cylindrical container.
