Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a nozzle blade drive device, in which variable nozzle blades of a turbocharger is driven by a drive ring through a link mechanism and the link mechanism is driven by a cam mechanism to increase a drive force so as to prevent vibration of the nozzle blades caused by a reaction force generated when exhaust gas is restricted by the nozzle blades and to stabilize an engine output control. SOLUTION: A nozzle blade drive device for a turbocharger is a device for driving the plurality of nozzle blades 41 for flow rate control disposed in a flow passage connecting a scroll 42 with a turbine rotor chamber 47 by the drive ring 43 disposed coaxially with a turbine rotor. The nozzle blade drive device for the turbocharger includes: the link mechanism 2 disposed to allow rotation of the drive ring 43 in a circumferential direction; the cam mechanism 3 operating the link mechanism 2; and an urging means 23 urging an abutment part, which abuts on a cam face of the link mechanism 2 and copies the cam face, onto the cam face.
