Abstract:
1. A linear actuator comprising: a body, an output member slidably received in the body along a first axis, a motor unit for producing a rotary motion about a second axis, and a motion conversion mechanism for converting the rotary motion produced by the motor unit about the second axis into a translational motion of the output member along said first axis, wherein the motion conversion mechanism includes a driving pulley arranged to be set into rotation by the motor unit about the second axis and an elongated mechanical transmission member wound onto the driving pulley, at the elongated mechanical transmission member having two opposite ends fastened to the output member to draw the output member in either direction along the first axis as a result of the rotation of the driving pulley in either direction, wherein the output member is shaped as a rod and is received in a cylindrical cavity of the body so as to project partially therefrom, and wherein the elongated mechanical transmission member is fastened to the output member at axially opposite points of the output member with respect to the driving pulley.
