A flexible wire assembly of a compact structure that can transmit the torque for a high speed rotation even in a bent condition is provided. The flexible wire assembly includes a flexible outer tube, in which a flexible inner wire having its opposite ends defining rotation input and output ends, respectively, is rotatably supported by means of a plurality of rolling bearings. Spring elements are employed for applying preloads to those rolling bearings. The use is also made of a speed reducing mechanism for reducing in speed and outputting rotation of the inner wire. The spring elements include inner ring spring elements and outer ring spring elements that are alternately arranged over the length of the inner wire.
