<p>PROBLEM TO BE SOLVED: To arrange an accompanying constitution such as stopper with a simplified structure and operation by a yoke material coupling between a plurality of rails being in a gate shape and utilizing a protrusion formed inwardly thereof for locking the accompanying constitution or load support. SOLUTION: An intermediate part yoke material 15 for coupling first rails 11 and 12 and an end yoke material are formed in identical shape and gate- shaped flat plate shape. Further, at the vertical intermediate part on a relative face such as side plate part 15B, an inward protrusion 15C or the like is integrally formed. By rotation operation of a nut body 28, double-screw rods 26 and 27 are tightened in approaching direction each other, thereby making it possible to fix the side of a division rail 10A to the side of a ceiling beam material 5 in stopped state via suspending means 20. At this time, a tightening force acted on the side of the yoke material 15 is received via a protrusion part 15C or the like to which a hook part 27a is locked.</p> |
