<p>PROBLEM TO BE SOLVED: To secure a specified mounting strength and reduce leading-in force for a wiring and piping member by laying a supporter which opens upwards between master beams for a receiver for a wiring or piping member and installing, inside the supporter, a container which rotatably stores a rotary roller in a state such that the roller projects higher than the opening of the supporter. SOLUTION: When leading a cable W into a wiring and piping member receiver 1, the cable W is mounted on a rotary roller 4 first and then is led in. Since the rotary roller 4 rotates, being stored in a supporting section of a storing body 6, the leading-in force can be reduced. The rotary roller 4 is supported in the storing body 6, and the storing body 6 is supported in a supporter 5, being in close contact with an inner face of the supporter 5. Therefore, the load at the time of leading in the cable W is supported by the supporter 5, having a rigidity through the rotary roller 4, not by a member of a roller shaft for turning the rotary roller, and thereby the mounting strength of the entire body of a slave beam 3 can be increased.</p> |
