<p>PURPOSE:To conduct alignment easily by forming a center line at the center of the base of a duct body for housing a wiring and a slot in the cross direction and forming a center mark on the main body side of the base of an ancillary base and a slot in the cross direction to the base. CONSTITUTION:A center line 13 is shaped at the center of the base of the main body base 10 of a duct body 1, in which a wiring is housed, and slots 12 extending in the cross direction are formed near both ends and the main body base 10 is fixed by screws. A center mark 23 is shaped to the main body side of the base of the ancillary base 20 of a coupling 2 connected to the main body base 10, and a slot 22 extending in the cross direction is formed to the base and the ancillary base 20 is fastened by a screw. Projecting sections 11c, 21c formed inside both side faces 11a, 21a of the cover 11 of the main body base 10 and the cover 21 of ancillary base 20 are engaged with recessed sections 10c, 20c formed to both side faces 10b, 20b of the main body base 10 and the ancillary base 20. Accordingly, alignment is easily conducted accurately by slots 12, 22, and the efficiency of wiring operation is improved.</p> |
