Abstract
In a rotary connection device, since a film of a solid lubricant is coated on both sides or one side of the flat cable, only the film and the surface facing thereto, or the films slide with each other at the time of tightening or loosening the flat cable, and thus the sliding friction can be reduced at the time of rotational sliding.
