Through passage forming members for wiring and piping materials

Abstract

This article relates to a through passage forming member for wiring and piping materials, which is used when wiring materials such as cables and piping materials such as electric wires and drain pipes are laid through wall materials, etc. Explained with reference to a front view of the sloped state, a reference exploded perspective view, and a reference view of the usage state, this article consists of a flange part and a sleeve part assembled to the flange part so as to be swingable, and a drainage pipe or the like can be laid inside this article by inserting the sleeve part into the back of the wall through a through hole formed in the wall material. In this case, the sleeve part can be swung obliquely relative to the flange part to create a drainage slope.
