Abstract
The flow-through characteristics of twin exhaust gas scroll passages of a turbine are made equal to each other. A tongue which partitions the scroll portions into outer peripheral portions and inner peripheral portions includes a front-side tongue and a rear-side tongue that respectively close the two exhaust gas passages at the outer peripheral portion. The inner sides of the front-side tongue and the rear-side tongue, and the minimal outflow width portions of the front-side passage and the rear-side passage, respectively, are formed substantially parallel to each other at a downstream end of the outer peripheral portion.
