| description | Drive member for timepiece movement comprising: a barrel comprising a drum mounted on an arbor; a main spring wound inside the barrel, and a core coaxial with and pivoting on the arbor; the exterior end of the spring being coupled to the drum and the interior end of the spring being coupled to the core; the exterior end of the spring is coupled to the drum by a first clamp that is pivot-mounted in the drum so that when the spring is unwound, the first clamp pivots in such a way as to hold the exterior turn of the first spring against the drum and when the spring is wound up, the first clamp pivots towards the center of the barrel to follow the exterior turn of the spring. The bending stresses in the spring are reduced. |
