ABSTRACT:
A linear/rotary actuator capable of carrying out both linear motion and rotary motion either individually or concurrently as desired while controlling both motions as desired. A rotary driving motor includes a hollow shaft. When the rotary driving motor rotates a third nut fitted on a spline section of the rotary driving motor, an output shaft rotatably fitted on a linear shaft through bearings is rotated. The linear shaft 21 is provided thereon with a threaded section. A spline section and a first nut is threadedly fitted on the threaded section and a second nut kept stationary is fitted on the spline section. The first nut is rotated while being fixed in a hollow shaft of a linear driving motor. Rotation of the linear driving motor leads to rotation of the first nut, resulting in the linear shaft 21 being linearly moved in an axial direction thereof, so that the output shaft may be linearly moved.
