ABSTRACT:
An anti-rotation mechanism in a linear actuator has outer and inner cylinders, affords high accuracy and rigidity, is simple in structure, not requiring the use of a tie rod, and is inexpensive to manufacture. The outer cylinder 3 has both end portions 3 of circular cross section and an intermediate portion whose inner surface has an axially uniform non-circular cross-sectional shape including a rotation inhibiting surface 3F. The inner cylinder 4 has a collar 7 on the outer peripheral surface which is guided and supported slidably by the intermediate portion of the outer cylinder and has a conforming non-circular cross-sectional shape including a flat surface 7B for sliding engagement with the rotation inhibiting surface 3F to inhibit rotation of the inner cylinder.
