Abstract
A turbocharger gas casing includes a scroll part forming a plurality of scroll passages at a same position in an axial direction of the turbine. The plurality of scroll passages include a first scroll passage. The first scroll passage is configured so that an extension line of a line segment connecting a farthest position from a rotational axis of the turbine at an inlet for an exhaust gas of the first scroll passage and a position of a tip of a tongue part formed on an inner peripheral side of the first scroll passage does not intersect a rotor blade of the turbine in a cross section of the turbine orthogonal to the axial direction.
