Abstract
A two-flow-passage type exhaust gas driven turbocharger, in which a scroll portion in a casing is divided by an annular partition to form two flow passages, the turbo-charger being constructed so that the difference between the temperature of the outer surface of the portion of the casing to which the partition is fixed and that of the partition can be minimized so as to reduce the thermal strain in the partition and thereby prevent thermal fatigue cracks from occurring therein.
