A flexible shaft 13 for transmitting torque, for example between a motor and an automobile seat to be adjusted. The shaft 13 has a core 15 including one or more wire layers 16 helically wound in opposite winding directions. The outer layer has a number of wires 22a, 23a, 24a, 25a with a circular cross-section and at least one flat wire 21a. The wires of the outer layer are helically wound in a winding direction opposite to that of the adjacent layer. The flat wire 21a has a thickness substantially less than the maximum diameter of the outer layer wires of circular cross-section. A strand 26a of flocked yarn is wound on the flat wire 21a and protrudes above the adjacent wires 22a, 23a, 24a, 25a of the outer layer, to engage the inner wall of a surrounding casing and reduce noise when the shaft is rotated within the casing. |
