Abstract
A shock-absorber device for a wheel arbor of a micromechanical device includes a support which includes a turning-arbor delimited by a rim defining a housing into which a pivot module is inserted. The pivot module includes a setting having a central orifice into which is inserted a bored stone. An endstone is placed on top of the bored stone. The shock-absorber device also includes a spring ring arranged between the support and the pivot module. The shock-absorber device is equipped with a bayonet system for mounting the spring ring. The bayonet system includes a peripheral shoulder under which is formed a circular groove which defines a holding area. The spring ring is equipped on an outer periphery with at least one catch. At least one first notch which leads to the circular groove is provided in the peripheral shoulder.
