<p><P>PROBLEM TO BE SOLVED: To properly shorten and extend a flexible wiring duct of a bellow structure used for a curved wiring portion. <P>SOLUTION: Spigots 3 that are inserted into ends of straight wiring ducts 16 are provided continuously on ends of a wiring duct body 2 of the bellow structure, and shortening cum extending spigots 4 are continuously provided between the spigots 3 and the wiring duct body 2. Locking portions 8 are formed protrusively from inside surfaces of the spigots 4, and first cutting grooves 9 are formed at one end side of the locking portions 8 of the spigots 4. Second cutting grooves 10 are formed at the other end side of the locking portions 8 of the spigots 4. The duct is shortened by cutting off the spigots 3, 4 integrally at the first cutting grooves 9 by fitting the spigot 4 to the outside of the end of the wiring duct body 2, and by fitting the locking portions 8 into the bellow structure of the wiring duct body 2. The duct is extended by cutting off the spigot 3 at the second cutting groove 10 by externally by fitting the remaining spigot 4 to the outside of the end of the other wiring duct 2' of the bellow structure, and by fitting the locking portion 8 into bellow grooves 7 of the other wiring duct 2'. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
