Abstract
As shown in the reference drawings, this article prevents rail breakage by, for example, using two of the article to sandwich the underside of the rail. The bottom plate portion of the article is used in a state where it is placed on the underside of the rail. Alternatively, holes may be drilled in multiple locations on the article and two of the article may be joined using connecting members, or bolts may be used to prevent the rail from slipping out of the article. Furthermore, rail breakage can also be prevented by sandwiching the underside of the rail between the bottom plate portion and protruding piece of one of the article.
