1. A turbine comprising:
a turbine wheel;
a housing including a flow path to direct therethrough a gas received from an inlet port;
a variable geometry device disposed inside the housing, and configured to receive the gas from the flow path and guide the gas to the turbine wheel, the variable geometry device including a disc-shaped nozzle ring having a main surface and a rear surface opposite the main surface, and nozzle vane members including:
nozzle vanes disposed adjacent to the main surface of the nozzle ring;
nozzle shafts extending respectively from the nozzle vanes and through the nozzle ring; and
nozzle link plates disposed adjacent to the rear surface of the nozzle ring and connected to distal ends of the nozzle shafts, respectively; and
one or more biasing members in contact with the nozzle link plates, to primarily apply a biasing force in an axial direction of the nozzle shafts, wherein the biasing force urges the nozzle link plates away from the nozzle ring.
