Timepiece movement, has elastic fixation device fixing bridge to plate and comprising elastic unit fixed to bridge, where elastic unit exerts elastic action on projecting element for tightening plate and bridge against each other

摘要

The movement has an elastic fixation device (5) for fixing a bridge (2a) to a plate (1). The fixation device comprises a projecting element (6) coupled and fixed to the plate. An elastic unit of the fixation device is fixed to the bridge. The elastic unit exerts an elastic action on the projecting element for tightening the plate and the bridge against each other. A free end of the elastic unit cooperates with a throat of the projecting element for exerting the elastic action. The elastic unit has elastic arms (7) that are arranged in the form of V joined in a rigid lug (8).
