    • A managing structure for an umbilical member of an industrial robot, the umbilical member being for supplying air and electric energy to a work tool attached to an end of a wrist of the robot, in which the umbilical member is properly moved and interference between the umbilical member and a peripheral object or a forearm of the robot is prevented. The umbilical member elastically contacts a guide surface of a guide plate attached to a second wrist element of the robot without widely projecting from the robot. The umbilical member is guided such that the extending direction of the umbilical member generally coincides with the longitudinal direction of the guide plate before the umbilical member is connected to the work tool. The thickness of the guide plate may be gradually reduced or constant toward a free end of the guide plate. The rotational motion about a third axis of the work tool by a final axis of the robot is converted to the rotational motion about a fourth axis via a transmission, so as to rotate the work tool. Even when the work tool is rotated, the umbilical member is properly moved. The work tool may also be rotated about the third axis.

A second wrist element 12 is rotatably provided around a second axis line B, on the first wrist element 11. A welding torch 2 is rotatably supported around a line C via a transmission mechanism 13. The third axis line C is disposed approximately perpendicularly to the axis line B and is remote from the axis line A by a predetermined distance. A wire feeder 4 is disposed at a position (on a mounting table 8, an upper arm, or a rotating body) other than a forearm. A torch cable 3 is fitted to a slider 6b that is movably fitted along a direction approximately parallel with the first axis line A, with an intermediate fitting section 3a. A slider 6b can be pulled backward by returning a wire 81 connected to a tension generator 80 using a pulley 82. In place of the fitting section 3a, an intermediate guiding section can be provided, and the torch cable 3 can be movably guided along a direction approximately parallel with the first axis line A. With this arrangement, an excessive looseness or tension of the torch cable and an occurrence of interference with the wire feeder can be prevented.
