OPENING DEGREE REGULATING STRUCTURE FOR VARIABLE NOZZLE MECHANISM, AND VARIABLE CAPACITY-TYPE TURBOCHARGER

摘要

The present invention is characterized by comprising: a variable nozzle mechanism section (23); an opening degree regulating means (43) that regulates the angle of a nozzle vane (19a) by bringing the outer peripheral surface (41) of the inner tube of a bearing housing (13) to which a nozzle mount (21) is affixed and the inner peripheral edge surface of a lever plate (33) into contact; and a discharge recess (47) that discharges soot which accumulates in the gap between the inner peripheral edge section of the lever plate (33), the nozzle mount (21), and the bearing housing (13) to the inner peripheral edge section of the lever plate (33), said section defining the outer periphery of the opening degree regulating means (43).
