A remote control cable (C) comprising a central core that moves axially while being guided in a sheath (5) by rolling and sliding members between first and second diametrically opposite rails, and an outlet rod (A) connected to each of the ends of said core and sliding inside a respective sheath end

A remote control cable (C) comprising a central core that moves axially while being guided in a sheath (5) by rolling and sliding members between first and second diametrically opposite rails, and an outlet rod (A) connected to each of the ends of said core and sliding inside a respective sheath endpiece (B).The cable is characterized in that the sheath endpiece (B) includes between its inner face and the outer surface of the outlet rod (A), axial guidance (20) for guiding said rod and for reducing radial friction between the rod (A) and the endpiece (B); the axial guidance (20) for the outlet rod (A) including at least one ring (20) of length that is sufficient to provide axial guidance of the rod relative to the endpiece (B).The ring (20) is made up of two coaxial cylindrical elements, an inner element (30) and an outer element (40) defining between them cages (14) in which trains of balls (10) are enclosed, the cages (14) comprising at least one cavity (15) opening out at least in part into the inner surface (32) of the inner cylindrical element (30) so as to enable rotary contact between said balls (10) and the rod (A).Balls one disposed between the inner wall of the endpiece (B) and the outer surface of the rod (A) in such a manner as to be capable of coming into rotary contact with the outer surface of the rod (A).

1. A remote control cable (C) comprising a central core that moves axially while being guided in a sheath by rolling and sliding members between first and second diametrically opposite rails, and an outlet rod (A) connected to each of the ends of said core and sliding inside a respective sheath endpiece (B), the cable being characterized in thatsaid sheath endpiece (B) includes between its inner face and the outer surface of said outlet rod (A), at least one ring serving both to convert radial forces into axial movement, and to guide said rod axially relative to said endpiece (B); said ring being made up of two coaxial cylindrical elements, an inner element and an outer element defining between them cages in which trains of balls are enclosed, said cages comprising at least one cavity opening out at least in part into the inner surface of said inner cylindrical element so as to enable rotary contact between said balls and the outer surface of the rod (A) in such a manner as to reduce friction between said rod (A) and the endpiece (B).
