PROBLEM TO BE SOLVED: To provide a device for elastic guidance in rotation which is compact and economical to manufacture and has good performance in use.SOLUTION: A device 2 for elastic guidance in rotation for a timepiece mechanism allowing rotation of one element relative to another element about an axis of rotation defining an axial direction comprises construction blades 4a, 4b each comprising an assembly fixing part. The assembly fixing part comprises a main part 13a, 13b and a functional portion 10 that extends from the main part 13a, 13b to one end. The assembly fixing part and the functional portion 10 are separated by at least one slot 12 provided in at least two extension portions 17, which are elastically connected to each other and extend in a radial direction transverse to the axial direction. The device also comprises anchorage zones 9, 11 which are disposed at flexible opposite axial ends and configured to be fixed to the elements.SELECTED DRAWING: Figure 1a |
