A drive unit for awnings and roller blinds is disclosed. The drive unit is adapted to be installed in a tubular shaft upon which an awning cloth or the roller blind is to be wound. More specifically, the unit comprises the following components which are arranged along a common axis: an electric motor; a reduction gear; a shut-off unit with associated setting means; and a coupling member adapted to transmit the torque from the reduction gear to the tubular shaft. In accordance with the invention, the reduction gear is arranged between the electric motor and the shut-off unit. Additionally, a hollow gear wheel is provided as the coupling member. The latter gear wheel is adapted to support and to be drivingly connectable to the surrounding tubular shaft, and is also in driving connection with the reduction gear. With the drive unit designed as above, its axial dimension can be made relatively short. |
