    Abstract: PROBLEM TO BE SOLVED: To provide an exhaust turbosupercharger having a variable nozzle mechanism component capable of maintaining low manufacturing cost, capable of holding firm tightened state, and having stable quality by tightening the component of the variable nozzle mechanism by less man-hours. SOLUTION: In this variable nozzle mechanism component of the variable displacement type exhaust turbosupercharger, a variable nozzle mechanism varying the vane angles of a plurality of turnably supported nozzle vanes is installed in a case member including a turbine casing. When a shaft-like member fixed to the through-hole of a through-hole-formed member having the through-hole among the components of the variable nozzle mechanism is manufactured, a wear resistant material higher in hardness and larger in wear resistance than a steel plate is built up by a prescribed thickness on the upper surface of the steel plate, and the shaft-like member with a prescribed outer diameter is cut out from the built up part of the wear resistant material and the steel plate.
