A ball bearing control assembly includes a cylindrical flexible sheath. A pair of stationary races defines a first raceway. A force transmission member defines a second raceway on opposing sides. Rolling members have a center point and are in rolling contact with the first and the second raceways as the force transmission member translates axially within the sheath. A ball guide interacts with the rolling members to constrain the majority of the rolling member. In one example, the ball guide interacts with the rolling members at two locations on each axial side of the rolling members. The two locations are positioned at different distances from the second raceway. The stationary races are located between the ball guide and the flexible sheath, and the ball guide is located between the stationary races and the force transmission member. Other examples can include two ball guides.

A parking cable has a plurality of plastic split type liners, which reduces frictional resistance between the inner cable and a conduit among the components of the parking cable. The plurality of split type liners is press-fitted and disposed to a desired position in an inner diameter of the conduit. The plastic split type liners may serve as a guide that ensures force for smoothly moving the inner cable and also improve in-line assembly properties. A method of manufacturing the parking cable includes press fitting the plurality of split type liners between the inner cable and the conduit.

A drive cable for actuating a vehicle element which is movable with respect to a vehicle design, which can have a cable body having a flexible cable core which is wrapped with a spiral, which follows a helical line so as to become engaged with a gearwheel. At least three longitudinal ribs or crosspieces can be formed along the periphery of the cable body, said drive cable being able to support itself in a cable guide via said longitudinal ribs which form at least mostly continuous guiding lines and contact lines of the drive cable, each having the same distance all around to the cable axis. Alternatively, an elastically or plastically malleable cable jacket can be provided which engages over the cable core and the spiral and which forms a cylindrical and rib-free peripheral surface of the cable when the cable core is stretched.

The invention relates to a flexible shaft (1) with a spiral coil (3) arranged on a core (2) of the cable (1) and with a catch (4) arranged at one of the cable ends for transmitting a force, for example to sliding roofs or cargo hold covers of motor vehicles. In order to further simplify the production of the flexible shaft (1), the invention proposes providing a bore (5) in the catch (4), with an inner section (7), in particular an internal screw thread, corresponding to the spiral coil (3).

A sliding component comprises a base member, a plated layer, and a lubricant agent. The plated layer includes a metallic material and is disposed on the base member. The lubricant agent includes a fatty acid containing a carboxyl group. The lubricant agent contacts the plated layer.

An operating wire has a multi-twisted structure constituted by twisting side strands, each formed by twisting element wires together around a core strand. A side element wire of the side strand faces the outside of the operating wire in the radial direction at a site located on the outer circumference of the operating wire and has a flattened surface where a flat portion provided in a portion of the side element wire in the circumferential direction extends in the X axis direction, the length in the X axis direction of the flattened surface being 4.8-11.0 times the diameter of the side element wire, and the pitch magnification of the side strand being 7.0-12.0 times the diameter.

The present invention relates to a medical instrument capable of enhancing the slidability of an operating wire in a lumen. The medical instrument (for example, a catheter (10) of the present invention) includes: a medical instrument body (a sheath (16)) which has a long length and flexibility and is inserted into a body cavity; a lumen (for example, a sub-lumen (30)) which is formed in the medical instrument body along a longitudinal direction of the medical instrument body; and an operating wire (40). The operating wire (40) is accommodated in the lumen, extends along a longitudinal direction of the lumen, and is slidable in the longitudinal direction of the lumen, and the medical instrument body can be bent by an operation of pulling the operating wire (40). A lubricating liquid (45) adheres to at least a surface of the operating wire (40).
