Abstract: An apparatus for guiding a threaded spindle in rotation, which spindle is used to ensure the displacement in translation of a mobile element connected to a threaded female piece engaged on this threaded spindle, which threaded spindle has a certain length and is connected, by one of its opposite ends, to a motor device for driving in rotation about its longitudinal axis in such a way as to allow the displacement in translation of the threaded female piece, wherein this apparatus includes at least one device for elastic absorption of an axial force which force, directed axially with respect to the threaded spindle and toward either one of its opposite ends, arises between this threaded spindle and the threaded female piece, and which force, when exceeding a certain limit, is considered likely to distort in particular the surfaces by which the threaded spindle and the threaded female piece cooperate.
