摘要：Inner cases are connected to outer cases through joining flanges which protrude toward outer peripheries of the outer cases. A plurality of combinations each including filters, the inner cases, and the outer cases are provided. Both the joining flanges are sandwiched and fixed between a pair of sandwiching flanges, thereby connecting the plurality of outer cases to each other.
主权项：1. An exhaust gas purification device comprising: a filter for purifying exhaust gas discharged from an engine; inner cases incorporating the filter; and outer cases incorporating the inner cases; and wherein the inner cases are connected to the outer cases through a pair of joining flanges which protrude toward outer peripheries of the outer cases; wherein the exhaust gas purification device includes a plurality of combinations of the filter, the inner cases, and the outer cases; wherein both the joining flanges are sandwiched axially and fixed between a pair of axially opposed sandwiching flanges, thereby connecting the plurality of outer cases to each other; wherein each of the sandwiching flanges is comprised of a plurality of units divided in a circumferential direction of the outer case, and the plurality of units surround an outer periphery of the outer case; wherein a support body for supporting the outer case on the engine is fastened to at least one of the sandwiching flanges; and wherein a support body fastening portion on which the support body is fastened is provided on one unit among the plurality of units comprising the sandwiching flanges on which the support body is fastened.
