    摘要： A barrel includes a mainspring cooperating internally with a core, externally with a track of a drum by way of a resilient sliding bridle. The track and the bridle are of non-circular shape, nesting one inside the other in the free state of the bridle. The track and the bridle are arranged to make one raised portion of the bridle abuttingly engage with a sill of the track when the torque applied to the bridle is less than a torque limit value, and to allow radial constriction of the raised portion when the torque is greater than the limit value. The track and the bridle are arranged to allow the passage of the raised portion over the sill and to allow the bridle to travel angularly under the effect of the torque until the next encounter between the sill and the raised portion.
