A flexible transmission mechanism of the kind in which a core member extends longitudinally within a flexible conduit for relative displacement between the core and the conduit for power transmission, has its conduit at least in part of wire coiled to form an external screw thread and means for fixing or serving as an abutment for the conduit are screwed onto the conduit. Advantageously, a projecting end portion of the conduit enclosing a corresponding end part of the core connectible to an operating or operated part is capable of flexure with the core from a fixing position and the said means can be adjusted along the screw conduit to determine the length of the projecting part of the conduit. A rigid rod may be fixed to one or each end of the core and not leave the conduit or prevent the aforesaid flexure. The said means may take the form of a plastics nut or nuts. The wire, or one wire of the conduit may be of triangulated section the flanks and apex of which may be rounded. |
