Abstract
Embodiments of the present invention may include a variable nozzle turbocharger having a variable nozzle mechanism for controlling a flow velocity of exhaust gas to a turbine wheel. The variable nozzle mechanism includes a plurality of variable nozzles, a unison ring and a biasing member. The variable nozzles each have a nozzle vane. The unison ring is configured to adjust a degree of opening of the variable nozzles through rotation of the unison ring. The biasing member biases the unison ring so as to open the variable nozzles.
