Abstract
A linear actuator comprises a rotary driving source, a tube member which is supported by a support rib extending in a substantially horizontal direction along a side section of a base member, an internal movable member and an external movable member which are integrally displaceable along the tube member under the magnetic coupling action, a slide screw shaft which is connected to a drive shaft of the rotary driving source and which transmits the rotary driving force to the internal movable member, and a slide screw nut for the slide screw shaft to be screwed therein for converting the rotary motion into the rectilinear motion.
