Zusammenfassung:	An upstream exhaust assembly (48) of an exhaust apparatus (E) of the present invention comprises: a plurality of branch pipe portions (32), a single exhaust pipe portion (34), and an exhaust gas-purifying unit (40). The exhaust gas-purifying unit (40) is disposed on a vehicle-rear side of the engine (1) to allow a gas passage thereinside to extend approximately in a vehicle-widthwise direction, in top plan view. The upstream exhaust assembly (48) includes, on an exhaust upstream side of the single exhaust pipe portion (34), a section which curves to allow an exhaust downstream region of the section to be oriented toward one side of the vehicle-widthwise direction which is a direction coming close to the transmission (11), in top plan view. The single exhaust pipe portion (34) curves to allow an exhaust downstream region of the single exhaust pipe portion (34) to be oriented toward a vehicle-front side, in top plan view. This makes it possible to compactly lay out the upstream exhaust assembly (48) in an engin
