Abstract: A exhaust gas purifier includes a case having a flat transverse section including a pair of facing short sides and a pair of facing long sides, and configured to house a catalytic converter, and an inlet cone including a conical portion, and configured to connect an outlet of the turbine to an inlet of the case. The conical portion includes an inclined wall inclined from a mainstream of the exhaust gas to increase the transverse section of a path of the exhaust gas. A recess recessed inward is formed in a portion corresponding to each of the long sides of the inclined wall of the conical portion.
