Claims

[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 vertequerate, and each of the shell members is Exhaust gas treatment for a diesel engine, in which connecting parts that are formed and protrude outward from the cylindrical container are welded together in contact with each other, and particulates in exhaust gas flowing through the cylindrical container are removed. In the device, the connecting portion on one side that comes into contact is extended, and the connecting portion on one side is bent so as to surround the connecting portion on the other side, and the end of the connecting portion on one side is connected to the other side. An exhaust gas treatment device for a diesel engine, characterized in that the device is welded to the shell member. (2) A pair of shell members are brought together in the middle to form a cylindrical container that accommodates a trap body for collecting particulate therein, and a cylindrical container that is formed on each of the shell members and located 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 portions protruding from each other are welded together in contact with each other, and the connecting portions on one side that are in contact with each other are A diesel engine characterized in that the connecting portion is provided with a reinforcing portion that is inserted through the connecting portion on the other side, and the reinforcing portion that is inserted through the connecting portion on the other side is welded to the shell member on the other side. Engine exhaust gas treatment equipment.
