<P>PROBLEM TO BE SOLVED: To provide a good cable threading method to a grommet, which can improve the threading work efficiency at the time of threading a cable into a long grommet, and to provide a grommet expander. <P>SOLUTION: The grommet expander 10 is equipped with three pieces of first to third flexible long members 11, 12, and 13 for diameter expansion, which are to be passed into the hole of the long grommet, drive means 21 and 31, which displace these second and third flexible long members 12 and 13 for diameter expansion with both their ends supported into far positions, a frame 18, and a controller 20. The grommet is brought up near the center while expanding it to shrink the longitudinal dimensions by displacing these first to third flexible long members 11, 12, and 13 for diameter expansion into mutually far positions and flexing the centers of the first to third flexible long members 11, 12, and 13 for diameter expansion with both their ends supported. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
