Abstract

L'invention concerne une virole élastique pour balancier de pièce d'horlogerie. Selon l'invention, sa forme est la transformation géométrique d'un cylindre, cette transformation étant effectuée de manière à conserver la symétrie de rotation et à obtenir des parties concaves et des parties convexes, les parties concaves étant tangentes à l'axe du balancier 1 et les parties convexes formant des protubérances 6, 7, 8 sur l'arête de l'une desquelles on peut fixer le spiral 9, et sur lesquelles on peut agir à l'aide d'un outil pour effectuer la mise au repère. L'invention s'applique notamment à l'horlogerie.
