。[Claims for Utility Model Registration] A ceramic turbine housing that has a metal casing on its outer shell and is connected and fixed to a gas outlet pipe or inlet pipe to the turbine through the metal casing, The end of the turbine housing at the connection part is fitted to the fitting part of the gas outlet pipe or inlet pipe with the end of the turbine housing on the inside, and the flange surface provided on the metal casing and the gas outlet are fitted together. The pipe or the flange surface provided on the inlet pipe are coupled in abutting state, and the turbine housing is slidably fitted to the outer circumferential surface of the fitting part fitted to the turbine housing, and the turbine is connected to the turbine housing through the fitting part. disposing a displacement absorbing member in the connecting portion, the displacement absorbing member having a sleeve portion that elastically supports the housing and a flange portion that is slidably held between the flange surfaces that are coupled in the abutting state;
A ceramic turbine housing characterized in that the displacement absorbing member absorbs relative displacement caused by a difference in coefficient of thermal expansion in the connecting portion.
