The main body () is provided with an upstream-side inner pipe () and a downstream-side inner pipe () therein. The upstream-side inner pipe has a shroud portion () which is located in the wheel housing chamber () and extends along edges of turbine blades () of the turbine wheel (). The downstream-side inner pipe () is arranged in the exhaust passage () so as to be located on a downstream side of the upstream-side inner pipe (). A thickness (t) of the downstream-side inner pipe () is thinner than a thickness (t) of the upstream-side inner pipe ().
