動装置。 A lever is fixed substantially perpendicular to each of the blade axes of a plurality of variable stator vanes arranged radially on a constant radius and whose radially outer blade axes penetrate a fixed ring and protrude outward. The lever pins installed at the other end approximately parallel to the blade axis are connected by a drive ring, and the drive ring is moved in the circumferential direction to change the angle of the variable stator blade and control the power of the turbo. In the stationary blade drive device, there is provided a roller pocket extending approximately parallel to the blade axis approximately midway between the lever pin of the lever and the blade axis, and a roller pocket inserted into the roller pocket whose outer periphery is connected to the driving ring and the fixing ring. A variable stator vane drive device for a turbomachine, comprising a roller sandwiched between.
