Flexible centering apparatus for centering a flexible drive cable within a cylindrial cable housing, the centering apparatus formed of an elongated finned sleeve in which radially disposed fins engage the cable housing, the fins being free and unattached at their outer ends. In one embodiment, the centering apparatus is of uniform construction; in another embodiment, the centering apparatus is of dual durometer construction.

In combination with rotary power transmitting apparatus of the type including drive means, means for being rotatably driven by said drive means, and a flexible, torque transmitting cable between and operably connected to said drive means and said rotatably driven means and mounted for rotation within a generally cylindrical shaped cable housing, said drive means rotating said cable and thereby said rotatably driven means, a flexible centering device extending through said cable housing for concentrically centering said cable with respect to said cable housing, said centering device comprising: an elongated sleeve defining a generally circular cylindrical passage-way through which said cable passes, said cable being supported by said elongated sleeve in said cylindrical passageway for rotation relative to said elongated sleeve and a plurality of fins extending radially outwardly from said elongated sleeve and with respect to said cylindrical passageway a sufficient distance to contact the interior surface of said cable housing solely at the outer ends of said fins and to concentrically center said cylindrical passageway with respect to the interior of said cable housing, adjacent ones of said fins defining a space between one another and between the interior surface of said cable housing and said elongated sleeve, said fins being unconnected with one another at their outer ends, said fins each extending continuously longitudinally over a major portion of the length of said elongated sleeve, said centering device being dimensionally formed to be constrained against rotational movement within said cable housing.
