Title
(EN) EXHAUST GAS PURIFICATION DEVICE
(JA) 排気ガス浄化装置
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an exhaust gas purification device which can be handled easily and can be quickly assembled and disassembled, and so on while a small size of the device is maintained.

SOLUTION: The exhaust gas purification device 1 comprises: a body shell 31 and an outlet-side shell 41 which are cylindrical in shape and are detachably disposed in series along a direction of flow of exhaust gas; and a CSF 32 disposed inside the body shell 31. A heat insulation mat 322 is interposed between the body shell 31 and the CSF 32, a bulging portion 51 is provided in an end portion of the body shell 31 on the side of the outlet-side shell 41, and a flare portion 61 which gradually expands toward the body shell 31 is provided in an end portion of the outlet-side shell 41 on the side of the body shell 31, wherein the shells 31, 41 are connected with each other by means of a fastening device 7 which has a V-insert 71 extending over the bulging portion 51 and the flare portion 61, and an end portion of the CSF 32 on the side of the outlet-side shell 41 protrudes toward the outlet-side shell 41 more than the end portion of the heat insulation mat 322 and is positioned inside the end portion of the body shell 31.
