Claims

[Scope of utility model registration request]

A worm that is rotatably driven by an electric servo motor, a worm wheel meshed with the worm, an output shaft that transmits the rotational motion of the worm wheel, and an output shaft that transmits rotational torque in forward and reverse directions to the outside. In a servo actuator, the torque generating device is connected to a hydraulic stroke cylinder, a rack that moves linearly by the cylinder, and a rack that meshes with the rack and rotates the linear motion output from the hydraulic stroke cylinder. A servo actuator characterized by comprising a pinion that converts into motion output.
