<p>PURPOSE: To provide a wiring piping structure and its wiring piping molding method in a relatively rotating part, with narrow processing space only required to facilitate replacement, while corresponding to requirement of spreading an operating range of an industrial robot or the like and to requirement of improving reliability of built-in cable, hose, etc. CONSTITUTION: In a relatively rotating part formed of a fixed base 1 and a turn base 4, a cable introducing space 3 is formed in the inside of the fixed base 1, to introduce a coil shape-formed cable 2A in this introducing space 3, to fix a base end part 2a of this coil-shaped cable 2A to a side of the fixed base 1, to fix an end part 2b of this cable 2A to a side of the turn base 4, and further wiring is performed of the coil-shaped cable 2A to rise up so that its coil center 01 almost agrees with the center of rotation 0 of the turn base 4.</p> |
