Abstract
A flexible spindle suitable for transmitting a torque as well as an axial thrust is constituted by a plurality of helical spirals of wire all of the same length. Each spiral has opposite winding directions to the winding direction of the adjacent spirals and the outer diameter of each spiral is equal to the inner diameter of the spiral which surrounds it. The terminal ends of the spirals are assembled integrally with each other and with the terminal ends of a flexible member situated inside the innermost spiral. Each sprial has a length which is equal to that of the other spirals as measured along their axis when these are in their bent operating position and under those conditions under which they are designed to transmit torque and thrust, with the flexible spindle resulting not to be radially or longitudinally deformable when under stress, thus transmitting the forces without loss.
