アクチユエータ。[Claims for Utility Model Registration] 1. A trunnion pin that reciprocates in the axial direction of an actuator slides in a yoke groove provided in a yoke, thereby rotating a valve shaft attached to a swinging fulcrum of the yoke. In the torque actuator, a notch is provided at the end of the yoke groove, the angle between the notch and the axis of the actuator when the valve is fully open is 0°, and the trunnion pin is connected to the piston rod of the actuator. What is claimed is: 1. A torque actuator for driving a valve, characterized in that the torque actuator is removably attached to the mounting portion, and a pin portion that contacts the upper notch portion is eccentric with respect to the mounting portion. 2. At the mounting part where the trunnion pin is removably attached to the piston rod of the actuator,
A torque actuator for driving a valve according to claim 1, which is formed with serrations or splines.
