The drive (1) has an actuating element e.g. chain, pivoting a wing between an opened position and a closed position, where the drive is displaced in a drive housing (3). An opening (4) is clamped with the actuating element. The drive housing is formed as a closed rectangular hollow profile. The opening limits clamping of the actuating element at the hollow profile of the drive housing, so that the drive displaced in the hollow profile is fixed at the drive housing by a discharge element (6) inserted into the opening, where the drive comprises a discharge guide (5) for the actuating element. |
