Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a simply-configured exhaust device for a multicylinder engine that can suppress the decrease in an ejector effect.SOLUTION: The exhaust device includes: a plurality of independent exhaust passages 52 which are connected to an exhaust port of one cylinder or exhaust ports of a plurality of cylinders having a non-sequential order of exhaust; and a collection portion 56 with a diameter gradually decreasing toward the downstream side of the exhaust flow direction, and into which exhaust that has passed through the independent exhaust passages 52 flows. The downstream ends of the independent exhaust passages 52 are connected to the upstream end of the collector portion 56 in a bundled state. The collector portion 56 or an exhaust passage downstream of the collector portion 56 is provided with an obstacle member 59 that partially blocks the exhaust flow passage.
