Abstract:
1. An umbilical-member processing structure for an industrial robot which comprises a forearm having a tool managing and relaying device and a wrist with a proximal end rotatably connected to said forearm and having a work tool mounted on a distal end of said wrist, with an umbilical-member connected to said work tool being disposed to run along said wrist via said tool managing and relaying device: wherein said forearm has a first reduction gear which reduces a rotational speed of a driving source to rotationally drive said wrist, said first reduction gear having a first insertion hole for passing said umbilical-member into said first insertion hole; and, wherein said wrist comprises a first wrist element having a through-path in communication with said first insertion hole and rotatably connected to said forearm, and a second wrist element having a second insertion hole in communication with said through-path and rotatably connected to said first wrist element; and, wherein a conduit for passing said umbilical-member from one end to the other end is provided in said first insertion hole of said forearm, in said through-path of said first wrist element, and in said second insertion hole of said second wrist element; and, wherein, with one end of said conduit being inserted in said first insertion hole so as to permit a movement in an axial direction and in a direction of outer circumference of said conduit, the other end of said conduit is held on said second wrist element in a cantilever fashion by a conduit holding member so as to restrict a movement of said conduit in said axial direction of said conduit.
