A sandwich flange is provided between a plurality of cases of the cylindrical DPF casing 60, and the plurality of cases are connected to each other by the sandwich flange. The sandwich flange is constituted by a plurality of units 53a, 53b, 54a, 54b separated in a circumferential direction. In addition, butting portions at ends of the units 53a, 53b which are butted along the circumferential direction and butting portions at the other ends of the units 54a, 54b which are butted along the circumferential direction, are positioned such that their phases are shifted from each other. |
