A bicycle control cable is provided with a central wire and at least one resin string. The at least one string made of resin is spirally wound onto the radially outermost surface in a direction intersecting with a center longitudinal axis of the central wire with a pitch less than or equal to 1 millimeter. The at least one resin string defines a spiral gap between adjacent windings of the at least one resin string. The at least one resin string defines an outer sliding surface for reducing a sliding resistance of the central wire. The central wire and the at least one resin string define an inner wire configured to slidably move in an axial direction with respect to the center longitudinal axis of the central wire within an outer case to operate a bicycle component.

A tubular shaft for a tubular shaft instrument includes a hollow shaft component, an actuating rod arranged in the hollow shaft component, and functional elements that are attached at the distal ends of the shaft component and/or of the actuating rod. The actuating rod is axially displaceable relative to the hollow shaft component to move the distal sections of the functional elements toward one another, past one another, and/or away from one another. The actuating rod includes at least one bending area in which flexible segments and support segments alternate and in which the actuating rod has significantly less bending resistance than outside the at least one bending area. A friction-reducing layer on the at least one bending area of the actuating rod reduces the friction of the actuating rod on the inside wall of the shaft component.

A toothed cable includes a cable body, and a cap provided at a tip of the cable body. The cap includes a conical tip portion, and a cylindrical body portion provided on a side of a base end of the tip portion, when the toothed cable moves in a direction from a side of the cap toward a side of the cable body in a curved guiding path of a guide member, the cap moves so as to be in sliding contact with an outer wall portion, and the toothed cable is configured such that an end region of the cable body, which end region is on the side of the cap, contacts an inner wall portion of the guide member when the cap comes into sliding contact with an edge of a concave portion of the guide member to limit an angle ? at which the cap swings.

A bicycle cable includes an inner line and an outer sheath. The inner line connects a driving mechanism and a driven device of a vehicle therebetween. The driven device includes a brake device or a derailleur. The inner line is composed of a plurality of threads twining together. The inner line has a maximum outer diameter ranged of 1.2 mm, and a minimum outer diameter ranged between 0.90-1.0 mm. The outer sheath has an outer diameter ranged between 3.5-4.5 mm and an inner diameter ranged between 2.0-2.2 mm. The outer sheath is sleeved onto the inner line. A gap formed between an inner face of the outer sheath and the inner line has a maximum ranged between 0.8 mm to 1.3 mm.

The disclosed embodiments describe a method for producing a bent tubular shaft for a tubular shaft instrument as well as a tubular shaft produced in such manner as well as a tubular shaft instrument with such a bent tubular shaft. The tubular shaft is produced by providing a hollow shaft component and an actuating rod. The actuating rod in this case has at least one bending area in which flexible segments and support segments alternate. The at least one bending area of the actuating rod is provided with a friction-reducing layer before it is inserted into the shaft component in order to create a tubular shaft. The tubular shaft is then bent in an area that corresponds to the at least one bending area of the actuating rod.

[Object] A hollow stranded wire line, for manipulation, having an excellent torque transmittability is provided. [Solution] A hollow stranded wire line 2 for manipulation is a hollow stranded wire line 2 that is advantageously used as a stranded wire line for manipulation in a medical instrument, and a side wire 4 or a side strand which is an outermost layer has a forming rate that is greater than 100% and not greater than 110%.
