Abstract
A rotatable connector includes a stator having an outer cylindrical portion; a rotor having an inner cylindrical portion and rotatably supported by the stator; three or more flat cables received in an annular space defined between the outer cylindrical portion and the inner cylindrical portion, the winding direction of each flat cable being halfway reversed, and opposite ends of each flat cable being fixed to the stator and the rotor, respectively; and a holder rotatably disposed in the annular space and having three or more openings through which the reversed portions of the flat cables pass. A width in the circumferential direction of a first opening is set smaller than a width in the circumferential direction of a second opening different from the first opening, and a bending strength of the flat cable passing through the first opening is set greater than that of the other flat cables.
