PURPOSE: To reduce the number of tools by holding a cable with a guide, jointing plural pulleys with links, moving a press roller with a freely rotationable screw, co-moving the other pulleys with it and bending this cable.

CONSTITUTION: MI cable 10 is arranged between plural pulleys 5 and the 1st guide 9 and is supported with the 2nd guide 11. When a handle attached to a joint 14 is rotated, the screw 13 rotates and the slider 8A moves from the back of the body 1 to the front, and the press roller 16 bends this cable 10. The link 17 swings, the slider 8 moves in the grooved hole 4 and the pulley 5 draws the cable 10 in U-letter shape. The reduction of operating space, the improvement of workability, the uniformity of bent shape and the reduction of many tools and jigs can be realized.
