ABSTRACT OF THE DISCLOSURE In a variable nozzle structure for a turbine, moveable vanes for controlling variable cross section nozzles which lead to a turbine wheel are actuated by a drive unit which comprises an actuator for causing a linear motion to a rod member, a lever arm member which is pivotally supported by a part of the turbine casing and is connected to the rod member at its one end so as to be able to rotate about its pivot point with respect to a turbine casing when the rod member is driven linearly, a crank arm member which is integrally connected to a pin shaft which is securely attached to each of the moveable vanes and pivotally supports the corresponding moveable vane, and an engagement member which is fixedly attached to the lever arm member and is engaged with the crank arm member so as to cause the rotational motion of the crank arm member when the lever arm member is rotatively driven by the rod member. Thereby, accurate control of the variable nozzles can be accomplished with a simple structure.
