The worm wheel (3) is operatively connected to a chain actuator (4). A motor (5) is operatively connected to the worm screw (2) and configured to rotate the worm screw (2) around the center axis (C). At least one bearing (6) has a center axis coaxial with the center axis (C) of the worm screw (2). A bracket element (7) is fixed to a center shaft (3a) of the worm wheel (3) by means of an opening in the bracket element (7) configured to accommodate the center shaft (3a). The bracket element (7) comprises at least one axially extending recess (8) configured to accommodate the at least one bearing (6), the bearing (6) being configured to support the worm screw (2).
