VARIABLE DISPLACEMENT TURBOCHARGER AND CORRESPONDING METHOD FOR ASSEMBLING THE VARIABLE NOZZLE MECHANISM WITH WHICH IT IS EQUIPPED

It is provided with: a variable nozzle mechanism 23 for regulating a flow of exhaust gas to a turbine rotor 7; a link mechanism 35 for converting reciprocal displacement from an actuator that operates a variable nozzle mechanism into rotational displacement and transmitting the rotational displacement to an inner section of a bearing housing; and an engaging part 51 for engaging an output section of the link mechanism and an input section of the variable nozzle mechanism, and the engaging part 51 is constituted by a pin 46 and a pin insertion slot 45 where the pin 46 is inserted, and a smooth surface 47 is formed around an insertion position of the pin 46 so as to guide a tip of the pin 46 to the insertion position .
