A rotation-guiding device includes a fixed support and a movable support able to rotate around the fixed support about an axis of rotation, wherein an interface between the fixed and movable supports includes a bearing to guide the movable support in rotation about the fixed support, a flexible dynamic seal providing seal-tightness between the fixed support and the movable support that is mounted between a friction track secured to one of said supports and a mechanical structure secured to the other support, and which includes a metal spring to provide the contact force for the seal between the friction track and the mechanical structure. The dynamic seal may be mounted parallel to the axis of rotation so that the contact force is exerted parallel to the axis of rotation. |
