Abstract
Provided is an exhaust treatment device including a cylindrical shell into which an exhaust gas is introduced, and a flow channel pipe that penetrates through the cylindrical shell. One end of the flow channel pipe is connected to an exhaust-gas flow path of an internal combustion engine, and the exhaust gas is introduced into the cylindrical shell via the flow channel pipe. A pair of through holes, in which the flow channel pipe is disposed, are provided in a pipe wall of the cylindrical shell. A lid member configured to occlude one of the through holes is welded to the other end of the flow channel pipe so as to occlude an opening in the other end. The lid member is welded to the pipe wall so that the one of the pair of through holes is occluded by the lid member.
