Abstract
A device for elastic guidance in rotation for a timepiece mechanism allowing rotation of one element relative to another element about an axis of rotation Z defining an axial direction, including construction blades, each construction blade includes an assembly fixing part including a body and a functional part extending from the body as far as one end, the assembly fixing part and the functional part being separated by at least one slot in at least two extensions which are elastically connected and extend in a radial direction transverse to the axial direction, and anchorage zones which are disposed at opposite axial ends of the flexible guidance device, and configured to be fixed to the elements.
