<p>PROBLEM TO BE SOLVED: To pull out an electric wire easily from its tip, by forming a larger annular part at its upper part and an engaging hole for engaging a wire material at its lower part using an expanding member, and forming a cylindrical body for sliding vertically at the upper annular part. SOLUTION: A linear expanding member 2 is folded into two and inserted in a cylindrical body 1, and a larger annular part 3 is formed at its upper part. The cylindrical body 1 involves an inner diameter sliding vertically easily at the annular part 3. An engaging hole 6 for engaging an electric wire 7 is formed under the expanding member 2 by folding up one wire so as to be overlapped with the edge of the other one, and fixing the overlapped part with a sleeve 5. The electric wire 7 is inserted in the engaging hole 6 and is connected by twist-locking at its use. This wire passing tool is formed with the cylindrical body 1 at the outside of the expanding member 2, therefore, it is easy to conduct working without deflecting at the time of inserting from a small hole. By expanding or shrinking the annular part 3 using such easy operation as permitting the cylindrical body 1 to slide vertically, it is possible to guide the electric wire smoothly to an inspection opening.</p> |
