Abstract
An actuator (5) comprises a housing (4) with a motor (6) and a screw mechanism (9), said screw mechanism comprising nut (10) and a screw (11) one of which is rotatably supported with respect to the housing by means of a screw mechanism support (13) allowing relative rotations of the screw and the nut with respect to the longitudinal screw mechanism axis (28), and an actuating member (15) connected to the screw mechanism by means of an actuating member connection (26), such that on relative rotation of the nut and screw the actuating member is displaced with respect to the housing. The screw mechanism support and the actuating member connection allow rotations having at least one axis transverse with respect to the longitudinal screw mechanism axis, so as to compensate traverse loading and bending moments.
