摘要
An exhaust turbocharger equipped with a nozzle throat area varying mechanism can be provided in which brazing welding is achieved with a small number of man-hour and at low cost, and which is stable in quality without danger of fracture of brazing-welded parts of constituent members. The variable-throat exhaust turbocharger equipped with a nozzle throat area varying mechanism for varying the blade angle of a plurality of nozzle vanes supported rotatably by members including turbine casing, is characterized in that members having at least one through-hole with at least one shaft member to be inserted into the through-hole(s) to be fixed therein among constituent members of the nozzle throat area varying mechanism are connected by means of brazing welding.
