Abstract
One of the swing shaftsof the nozzle vanesis selected so as to operate as swing drive shaftthat projects to the outside. As the swing drive shaftis driven to revolve, all the nozzle vanesare driven to turn by a same angle by way of the driving leverand the coupling ringlinked to it. Therefore, it is only the swing drive shaftthat projects to the outside, the projecting part can be sealed in a simple and reliable manner to improve the sealing effect and the durability of the variable geometry turbocharger. Additionally, since the rotary motion of the swing drive shaftis directly used to driven the nozzle vanesto swing, the mechanism for transmitting the driving force is simplified.
