To prevent a flexible flat cable (hereinafter referred to FFC) from tilting by its own weight when the FFC is fed out in perpendicular posture and used by enhancing its self-standing properties without altering the structure thereof at all.

At any one or both of the connecting part in a movable section 10 and the fixed part in a fixed section 4, a supporting surface 33 having an upper part slightly inclining rearward and imparting self-standing properties to an FFC 8 is provided in order to prevent the upper part of the FFC 8 from tilting forward by its own weight due to the moving position of the movable section 10. A spacer 34 for urging the FFC 8 toward the supporting surface 33 inclining rearward is also provided.
