PURPOSE: To provide low-priced wiring with excellent quality by forming a first movable cable part with one end fixed close to the end part of a first rectilinear moving unit and with the other end fixed to the fixing part of a moving member, and a second movable cable part fixed to a moving part after being twisted in the moving direction of a second rectilinear moving unit. ;CONSTITUTION: In a first movable cable part 24, the nearly end part 24a is fixed, an approximately U-shape part 24b is formed along a first rectilinear moving unit 21, and the other end 24c is fixed to a moving member 23. Part 27 of cables is twisted by 90° in the moving direction of a second rectilinear moving unit 22. In a second movable cable part 28, an approximately U-shape part 28a is formed along the rectilinear moving unit 22 and fixed to a moving part. The movable cable parts 24, 28 are single continuous parts without a break. When the moving member 23 is moved, the other end 24c of the movable cable part 24 moves integrally with the moving member 24 while the position of the approximately U-shape part 24b at the intermediate part is changed along the flexibly changed shape of sheaths 30, 32 and air tubes 33.;COPYRIGHT: (C)1995,JPO
