エストゲート構造。[Claims for Utility Model Registration] A plurality of cylinders, a plurality of independent exhaust passages that lead out only the exhaust gas of the cylinders whose exhaust strokes do not overlap among the plurality of cylinders, and a plurality of independent exhaust passages that are divided in parallel in the circumferential direction of the turbine housing. In an engine equipped with an exhaust turbo supercharger, the exhaust turbo supercharger has a plurality of scroll parts each guiding exhaust gas from the independent exhaust passages. A plurality of wastegate passages that bypass exhaust gas downstream of the turbine are provided, and a swing valve that swings around a predetermined rotation axis to open and close a downstream end opening of each of the wastegate passages is provided. A waste gate structure for an engine with an exhaust turbo supercharger, characterized in that the downstream end opening of the waste gate passage is arranged such that the longer the passage length, the farther the waste gate passage is located from the axis of the rotating shaft.
