PROBLEM TO BE SOLVED: To provide a motor-driven actuator which can hinder the load of a work from being applied to a feed screw and is able to transport a heavy object. SOLUTION: The load of a work applied to a slide table 68 is supported by a guide block 78 and guide rails 30a and 30b mounted on a frame 12. A pin member 72 to constitute a floating mechanism 64 installed in the lower part of the slide table 68 is fitted slidably in a fit-in member 66 in approx. a channel shape. This hinders the load of the work from being transmitted to a ball screw through a member displaceable. |
