Abstract: Door with automatic opening and closing, including a door panel, a support column fixed to the door panel and suitable for rotating around its longitudinal axis in such a way to move the door panel between two end-of-travel positions, an electric motor for actuating the support column and a drive unit for transmitting the motion from the electric motor to the support column. The drive unit has a first drive element connected to the electric motor and a second drive element connected to the support column, wherein the drive unit includes a clutch unit that is interposed between the first drive element and the electric motor or between the second drive element and the support column. The door also has an automatic lock that completes the automation of the door by detectors.
