A turbocharger, comprising: a turbine wheel configured to be rotated by exhaust gas of an engine; a turbine housing which accommodates the turbine wheel and forms at least a part of a scroll flow path through which exhaust gas to be supplied to the turbine wheel flows; a bearing housing which accommodates a bearing supporting a shaft of the turbine wheel rotatably, the bearing housing being coupled to the turbine housing; a shroud having a facing surface which faces a tip of a blade of the turbine wheel and being configured to surround the turbine wheel, the shroud comprising a separate member from the turbine housing and being disposed inside the turbine housing via a gap with respect to the turbine housing; a mount supported to at least one of the turbine housing or the bearing housing, the mount being an annular member including an engagement portion engaged with an annular step portion formed on the bearing housing by socket-and-spigot fitting and is disposed at a position closer to the bearing housing than the scroll flow path in an axial direction of the shaft; and at least one connection part connecting the mount and the shroud, the at least one connection part exposed to exhaust gas flowing between the shroud and the mount, wherein the turbine housing includes a first housing formed of sheet metal, the first housing accommodating the turbine wheel and forming at least a part of the scroll flow path, characterized in that the shroud is disposed inside the first housing via the gap with respect to the first housing, and in that the turbocharger further comprises: an outlet guide tube configured to guide exhaust gas having passed through the turbine wheel; a seal ring which seals the gap between the shroud and the turbine housing; and a piston ring which seals a gap between the first housing and the outlet guide tube so that the first housing is slidable with respect to the outlet guide tube in the axial direction of the shaft. a turbine wheel configured to be rotated by exhaust gas of an engine; a turbine housing which accommodates the turbine wheel and forms at least a part of a scroll flow path through which exhaust gas to be supplied to the turbine wheel flows; a bearing housing which accommodates a bearing supporting a shaft of the turbine wheel rotatably, the bearing housing being coupled to the turbine housing; a shroud having a facing surface which faces a tip of a blade of the turbine wheel and being configured to surround the turbine wheel, the shroud comprising a separate member from the turbine housing and being disposed inside the turbine housing via a gap with respect to the turbine housing; a mount supported to at least one of the turbine housing or the bearing housing, the mount being an annular member including an engagement portion engaged with an annular step portion formed on the bearing housing by socket-and-spigot fitting and is disposed at a position closer to the bearing housing than the scroll flow path in an axial direction of the shaft; and at least one connection part connecting the mount and the shroud, the at least one connection part exposed to exhaust gas flowing between the shroud and the mount, wherein the turbine housing includes a first housing formed of sheet metal, the first housing accommodating the turbine wheel and forming at least a part of the scroll flow path, characterized in that the shroud is disposed inside the first housing via the gap with respect to the first housing, and in that the turbocharger further comprises: an outlet guide tube configured to guide exhaust gas having passed through the turbine wheel; a seal ring which seals the gap between the shroud and the turbine housing; and a piston ring which seals a gap between the first housing and the outlet guide tube so that the first housing is slidable with respect to the outlet guide tube in the axial direction of the shaft. an outlet guide tube configured to guide exhaust gas having passed through the turbine wheel; a seal ring which seals the gap between the shroud and the turbine housing; and a piston ring which seals a gap between the first housing and the outlet guide tube so that the first housing is slidable with respect to the outlet guide tube in the axial direction of the shaft.
