Abstract
A Bowden cable is provided that includes, but not limited to, a casing and a wire extending in a cavity of the casing. Points of contact between the wire and the casing are unevenly distributed on the circumference of the wire in each cross section. A clearance extends helicoidally along the wire. The helicoidal clearance has a pitch (L) at least equal to twice the diameter (D) of the wire. In each cross section the clearance extends around at least half of the circumference of the wire.

A Bowden cable, comprising:
- a casing having a cavity;
- and
- a wire extending in the cavity of said casing,
- wherein points of contact between the wire and the casing unevenly distributed on a circumference of the wire in each cross section and a clearance extending helicoidally along the wire,
- wherein a helicoidal clearance has a pitch at least equal to twice a diameter (D) of the wire and that in each cross section the helicoidal clearance extends around at least half of the circumference of the wire.

A casing for a Bowden cable, comprising:
- a central cavity;
- and
- a non-circular cross section of the central cavity having a shape of which a cross section rotates along said casing,
- wherein a pitch of a rotation of the cross section along said casing is at least equal to twice a transversal dimension of the central cavity.
