<p>PURPOSE: To make a cable extension work efficiently with a cable being prevented from coming off. CONSTITUTION: A first tightening means 8 is installed to pressure-weld a partial piece 11 of a stationary body such as a cable brace to a first-side piece 3 of an installation basic frame 1. A main piece 13 of an intermediary board 12 is pressure-weldedly laid on top of a central piece 2 by means of a second tightening means 16. A square connection piece 15 which always juts out from the installation basic frame 1 is formed, and an basic end of a guide substrate 19 is pressure-weldedly laid on top of the connecting piece 15 by means of a third tightening means 22. A supporting lever 27 which is constituted of a parallel lever section 26 is installed on the guide substrate by the rising lever section 25. An installation edge 34 such as a long cutout is formed in the guide substrate 19 in the longitudinal direction of the parallel lever section 26. A frame body 31 which is U-shaped when viewed from front face is removably assembled on the installation edge 34. On the frame body 31 and the supporting lever 27, guide rollers 21 are axle-supported so as to surround a cable C.</p> |
