Abstract
A turbine housing for a centrifugal turbosupercharger comprising a spiral wall defining a gas passage through which exhaust gas from an engine passes and a partition wall dividing said gas passage into two passages wherein the height of the partition wall gradually decreases in the downstream direction. In such a manner that the gap between the outer periphery of a turbine rotor and the tip of the partition wall reaches a maximum at about 225.degree. as measured from an intersection of the inner periphery of the partition wall and a line passing through the center of the turbine rotor and drawn perpendicular to the direction of introduction of exhaust gas.
