摘要： A vehicle forced-induction device includes a first exhaust turbine type forced-induction unit and a second exhaust turbine type forced-induction unit. The first forced-induction unit includes an outlet pipe. The outlet pipe includes a first tubular portion and an annular first flange. The second forced-induction unit includes an inlet pipe. The inlet pipe includes a second tubular portion and an annular second flange. The forced-induction device includes a fastener that includes an annular groove. The annular groove has a shape in which a width of the annular groove decreases toward a groove bottom. The fastener is wound around the first and second flanges along a circumference of the first and the second flanges, thereby housing the first and second flanges in the annular groove. The fastener fastens the first and second flanges to urge the first and second flanges toward each other.
