Abstract
A winding device (1), in particular of a barrel (2) provided with a spring, including a ratchet (3) mounted integrally on a rotary winding shaft, the rotary winding shaft being, for example, a winding shaft of the barrel (2), the rotation of which winds the barrel (2), and a winding gear train (4) meshing with the ratchet (3), the rotation of the winding gear train (4) causing the rotation of the ratchet (3) and that of the rotary winding shaft by application of a torque to the ratchet (3), wherein the ratchet is deformable in order to be able to disconnect the ratchet (3) from the winding gear train (4). Also, a horological movement comprising such a winding device (1).
