Abstract

A plurality of independent passages (51), a collecting passage (52), a catalyst device (6), and a swirling part (53) are provided to an exhaust passage, the plurality of independent passages (51) individually extending from exhaust port opening ends (12), exhaust gas that passes through the independent passages being collected in the collecting passage (52), the swirling part (53) connecting the collecting passage to the catalyst device (6) to cause the exhaust gas to swirl in the swirling part. The plurality of independent passages and the collecting passage have, as a whole, a shape that is bent in such a way as to bulge toward an exhaust side from the plurality of exhaust port opening ends and to extend downward, and the swirling part has a shape that causes the exhaust gas led out from the collecting passage to swirl about an axis extending along a cylinder arrangement direction.
