<p>An actuator (7) comprises a housing (4), a motor (8), an actuating member (25, 35) and a screw machanism (10) providing a linear movement of the actuating member (25, 35) with respect to the housing (4) in response to a rotational movement of the motor (8), said screw mechanism (10) comprising a screw (24) and a nut (22) one of which is rotatably supported with respect to the housing (4). The screw mechanism (10) and the actuating member (25, 35) engage each other through a resilient intermediate pressure means (28, 29, 36).</p> |
