Abstract
An exhaust gas purifying apparatus is comprised of a plurality of exhaust gas passages, and a filter bodyinstalled in the exhaust gas passages. The exhaust gas passage contains a filter-conducting portionof conducting the exhaust gas to the filter body, and a filter-bypassing portionof bypassing the filter-conducting portionby branching out to an exhaust gas passage adjacent from the filter-conducting portion. When PMs are deposited on the filter-conducting portionand an exhaust gas pressure loss is increased, the exhaust gas is branched out from the filter-bypassing portionto flow.
