A turbocharger includes: a turbine wheel that is driven by exhaust gas from an engine and supported rotatably by a predetermined rotary shaft; and a turbine housing that forms an exhaust gas passage that leads the exhaust gas to the turbine wheel, wherein the turbine housing includes a housing main body constituted by a plate-form member and a reinforcement member that forms the exhaust gas passage together with the housing main body and reinforces the housing main body, the reinforcement member includes a pair of annular portions having a substantially annular shape and provided about an axial center of the rotary shaft at an interval in an axial direction of the rotary shaft, and a connecting portion that connects the pair of annular portions, and the pair of annular portions and the connecting portion are molded integrally by implementing deformation processing on the plate-form member.

Turbocharger and manufacturing method for turbocharger

Method and apparatus for pressing a sheet blank into a tubular container, including a first process or device for drawing the blank into an intermediate workpiece having a tubular portion and a bottom portion closing one end of the tubular portion, and a second process or device for ironing the tubular portion in the axial direction. The second process includes a forward ironing step for placing the workpiece on a first ironing punch and forcing the workpiece and first punch together into a first die hole, to iron the tubular portion in an axial direction from the above one end toward the other end, and a backward ironing step for placing the workpiece on a columnar second ironing punch and forcing the workpiece and second punch together into a second die hole, with a columnar pushing punch held in pressing contact with the outer surface of the bottom portion of the workpiece, to iron the tubular portion in the direction opposite to that in the forward ironing step.
