摘要

ASSEMBLY ELEMENT INCLUDING SUPERPOSED STRIP SHAPED ELASTIC STRUCTURES AND TIMEPIECE FITTED WITH THE SAME Assembly element (18) made in a plate of brittle material, including an aperture (32) provided for the axial insertion of an arbour {26), the inner wall (33) of the aperture (32) including elastic structures (34), which are etched into the plate to grip the arbour (26) radially. Each elastic structure (34) includes a first rectilinear elastic strip (L[err]) which extends along a tangential direction relative to the arbour (26). According to the invention, each elastic structure (34) is formed by a radial stack of several parallel elastic strips.The invention also proposes a timepiece fitted with this assembly element (18).
