A turbine housing is formed which comprises a plurality of housing members. The distance between mating portions of opposite side walls of one housing member is a first distance and the distance between mating portions of opposite side walls at one end of an adjacent member in the direction of fluid flow in the turbine is greater than or equal to the first distance. The distance between the mating portions of opposite side walls at the other end of the adjacent member is less than or equal to the first distance. Further, the distance from the axis of the housing to the mating portion of the circumferential wall which connects opposite side walls of the one housing member is less than or equal to the radial distance to the circumferential wall at the one end of the adjacent member and the distance to the circumferential wall at the other end of the adjacent member is less than or equal to the distance from the axis of the circumferential wall of the one housing member.
