<p><P>PROBLEM TO BE SOLVED: To provide a drawing cover for wiring and piping materials that can be attached to and detached from a protection cylinder and has satisfactory workability, regardless of the drawing/lead-in work of the wiring and piping materials. <P>SOLUTION: The drawing cover 5 comprises a contact section 1 that comes contact with a building wall; a fixing section 2 used for fixing to the building wall; an insertion section 3 into which an edge 6a in the protection cylinder 6 is inserted; and an opening 4a that covers the periphery of the edge 6a and is opened in a direction opposite to the opening direction of the edge 6a of the protection cylinder 6. The cover section 4 has a bending section 4b inside. The bending section 4b bends the wiring and piping materials, withdrawn from the edge of the protection cylinder so that they are folded back toward the opening 4a. The cover section 4 allows the wiring and piping material folded back from the opening 4a to be withdrawn to the outside of the cover section 4. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
