<p>PURPOSE:To simplify the wiring of a wiring duct by specifying the disposition of the duct, forming the same connecting state of the ducts crossing at the joint portions to thereby enable to couple the respective joint portions at the same jointing unit. CONSTITUTION:Wiring ducts 1 are arranged in lattice state in combination of regular triangle, hexagon of 60 deg. or 120 deg. of internal corner angle or of parallelogram of both angle combination in such a manner that the opposite wire routes 1a, 1a of the ducts 1, 1 forming 60 deg. of the internal corner angle of parallel pair wire routes 1a, 1b wired in the duct 1 are the same polarity, and the opposite wire routes 1a, 1b of the ducts 1, 1 forming the 120 deg. of internal corner angle are different polarities.</p> |
