Abstract
An actuator () includes a body (), an output member () slidably received in the body () along— a first axis (X), an electric motor () arranged to set into rotation a motor shaft () about a, second axis (X) and a motion conversion mechanism () for converting the rotary motion produced by the electric motor () about the second axis (X) into a translational motion of the output member () along the first axis (X). The motion conversion mechanism () includes a driving pulley () which is drivingly connected for rotation with the motor shaft () and an elongated mechanical transmission member which is wound onto the driving pulley () and is fastened at its two opposite ends to the output member () to draw this latter in either direction along the first axis (X) as a result of the rotation of the driving pulley () in either direction. The output member () is shaped as a rod and is received in a cylindrical cavity () of the body () so as to project partially therefrom. The elongated mechanical transmission member (S) is fastened to the output member () at axially opposite points of this latter with respect to the driving pulley ().
