ABSTRACT:
The invention relates to an apparatus for rotatably driving a winding-up/unwinding support, particularly a winding-up/unwinding tube for a sail. This apparatus comprises a transmission shaft (7) having an upper extremity provided with means for fixation (8) to a support, a manual control member (9, 10, 11) able to be actuated manually, a hydraulic motor (13) comprising a motor shaft (15) having one upper extremity of a form able to lodge the lower extremity of the transmission shaft (7), a clutch apparatus controlled by means of a fluid under pressure and having a clutch member (27) movable along the transmission shaft (7) and adapted to solidly connect said transmission shaft and the motor shaft (15) when the clutch apparatus is subjected to the pressure of the fluid, and the transmission shaft (7) and the manual control member (9, 10, 11) in the absence of fluid, and feed means adapted to simultaneously deliver a fluid to the hydraulic motor (13) and the clutch apparatus.
