Claims (5)

[Claims] A first cable holding member for forming a curved portion by relaxing a middle portion of the flexible strip-shaped conductor cable, and holding a cable portion routed in one direction from the curved portion; A second cable holding member that is arranged to face the first cable holding member at a predetermined interval and holds a cable portion routed in the other direction from the curved portion; and the first cable holding member and the second cable holding member. A connection shaft attached between the two cable holding members so as to be in contact with the curved portion disposed in a space sandwiched between the second cable holding members; and at least one of the cable holding members. A flexible portion of the flexible belt-shaped conductor cable, wherein the cable portion is rotatable with respect to the connection shaft, and the crossing angle of the cable portion arranged in each direction is variable. 2. The fixed structure of a flexible strip-shaped conductor cable according to claim 1, wherein one of the cable holding members is positioned at a tip of the connection shaft with respect to the other cable holding member. A curved portion fixing structure for a flexible strip-shaped conductor cable, comprising a guide holding portion that is slidably movable. 3. The curved portion fixing structure for a flexible strip-shaped conductor cable according to claim 1 or 2, wherein the first cable holding member and the second cable holding member have oppositely facing surfaces. And a cable guide groove for accommodating and guiding the flexible strip-shaped conductor cable is formed. 4. The structure for fixing a curved portion of a flexible strip-shaped conductor cable according to claim 1, wherein one of the first cable holding member and the second cable holding member is inclined to form the space. A curved portion fixing structure for a flexible strip-shaped conductor cable, wherein the portion is gradually widened from the connection shaft side toward the release end side. 5. The bending portion fixing structure for a flexible strip-shaped conductor cable according to claim 4, wherein one of the bending portions is provided on a facing surface of the first cable holding member or the second cable holding member. A curved portion fixing structure for a flexible strip-shaped conductor cable, comprising a cable guide having an inclined surface for supporting the portion.
