VARIABLE CAPACITY-TYPE EXHAUST TURBOCHARGER EQUIPPED WITH VARIABLE NOZZLE MECHANISM

A variable displacement exhaust turbocharger is provided with a plurality of nozzle vanes (2) that are rotatably supported by a nozzle mount (5), a drive ring (3) that is interlocked with an actuator (41) and fits to a guide part (5a) of the nozzle mount (5), a lever plate having one end coupled to the drive ring (3) and the other end coupled to the nozzle vane (2), and a variable nozzle mechanism that varies the vane angle of the nozzle vane (2) by rotating the drive ring (3). A bulge suppressing portion (5e) is provided for absorbing bulging occurring on an outer peripheral surface of the guide part (5a), the bulging being caused by the press-fitting of a nail pin (20) into a press-fitting hole (5b) in a direction slightly toward the rotational axis with respect to the guide section (5a) and following the axial direction of the nozzle mount (5).
