Variable capacity turbocharger

A variable capacity turbocharger comprising:

• a variable nozzle unit rotating a nozzle vane inside a nozzle flow passage of a turbine;
• a bearing housing accommodating a bearing supporting a rotation shaft of a turbine impeller of the turbine;
• a circular heat shield plate located between the turbine impeller and the bearing housing and surrounding the rotation shaft in a circumferential direction of the rotation shaft;
• and
• a water chamber which is provided in the bearing housing and circulates a cooling water,
• wherein the heat shield plate is sandwiched between the variable nozzle unit and the bearing housing together with a disc spring in an axial direction of the rotation shaft, is fixed by being pressed against the variable nozzle unit by the disc spring in the axial direction, and is aligned in a radial direction of the rotation shaft by being fitted into the bearing housing by a fitting portion extending in the circumferential direction,
• wherein the heat shield plate comprises:
• a fitting surface formed in the fitting portion and fitted into the bearing housing;
• and
• an inner peripheral heat shield portion projecting radially inward from the fitting surface and located with a gap between the bearing housing in the axial direction, and
• wherein at least a part of the water chamber exists at a same radial position as a radial position of the fitting portion.
