Abstract
Provided is a turbine housing that comprises: a scroll unit; a flat annular cover () that is disposed in a state where one end face abuts a flanged portion () of the scroll unit and that is welded to the flanged portion (); an annular seal portion () that extends from a basal end () welded to the inner circumferential side of the other end face of the annular cover () to the distal end () disposed further to the exterior than the basal end () in the radial direction and that comprises a member that can be elastically deformed; and a plurality of threaded bushings () that are each welded in a plurality of locations on the outer circumferential side of the other end face of the annular cover () and that have fastening holes () for fastening bolts () inserted along the direction of the axis of rotation. A sealing region that extends around the entire circumference of the axis of rotation is formed by elastically deforming the annular seal portion () by the distal end () being in contact with the outer circumferential face () of a bearing housing () by way of the bearing housing () being pressed toward the annular cover () via a seat face of a washer ().
