ABSTRACT:
A linear actuator wherein a load-bearing body or structure made of relatively heavy metal provides for flexibly supporting an electric motor, the output shaft of which is connected, via a belt drive, to a tubular shaft parallel to the output shaft of the motor, and connected in rotary manner, at a first point, to the load-bearing structure and, at a second point, to a plastic element integral with the load-bearing structure; the output member of the actuator consisting of a screw coaxial with the tubular shaft and connected to the same via a recirculating-ball screw-nut-screw coupling.
