[Problems to be solved by the invention]
However, in the above-mentioned structure, since the insertion of the flaky member into the option mounting groove and the cable wiring work are performed using the end of the support, the end of the support is used at the time of the work. There is an inconvenience that cautious work is inevitably required, in many cases, when the user gets caught. In general, the support of the structure is prepared by preparing a long-sized molded body as a support material by extrusion molding, and cutting it at predetermined lengths for use as a support. In this case, the cut edge of the end of the column is exposed as it is. Such cut edges may be subjected to chamfering or other edge treatments at the ends of the struts, but the struts forming the option mounting grooves and wiring spaces have a relatively complicated skeleton in cross-sectional shape. For this reason, the chamfering operation or the like is very troublesome operation, and causes a disadvantage that productivity is significantly reduced.
[0006]
[Object of the invention]
The present invention has been devised in view of such inconvenience, and its purpose is to eliminate the necessity of performing operations such as chamfering on the ends of the columns, and to maintain the cut-off state even when cut off.
