<p>The actuating element (1) has a housing (3) i.e. plastic tube, extending along a longitudinal axis (2), and a drive-shaft coupled to a drive device, where the drive device is designed as an electric motor and forms a support element. The drive-shaft is driven at the longitudinal axis in a rotatable manner. A spindle-drive comprises a thread-spindle provided with an external thread. A spindle-nut is provided with an internal thread adapted to the external thread. An adjusting element (19) is shifted in a direction of the longitudinal axis by the spindle-drive.</p> |
