Abstract: An actuating drive includes an actuating arm pivotally mounted about a pivoting axis for moving the movable furniture part, a spring device for applying a force onto the actuating arm, and a transmission mechanism for transmitting a force of the spring device onto the actuating arm. The transmission mechanism includes an actuating portion movement-coupled to the actuating arm, a setting contour, and a pressure portion pressurized by the spring device. The pressure portion is a rotatably mounted pressure roller for running along the setting contour. The setting contour is arranged between the actuating portion and the pressure roller, and the setting contour is on a contour portion separate from the actuating portion. The contour portion has a fastening section configured to rest against the actuating portion and a limb protruding transversely from the fastening section, and the setting contour is a curved outer surface of the limb.
