Claim:
A rotary connector device comprising: a first casing; a second casing mounted rotatably relative to the first casing; a support member arranged in an accommodation space that is formed between the first casing and the second casing; a cable including a conductor part and a covering part that covers the conductor part, and configured to electrically connect a first connector arranged in the first casing and a second connector arranged in the second casing to each other by the conductor part; and a roller rotatably supported on the support member, and configured to, when the second casing rotates relative to the first casing, bring an outer circumferential surface thereof into contact with the cable, thereby guiding the cable, wherein the roller is molded by using a die, when a plane including a parting line that is formed at the outer circumferential surface of the roller at a time of the molding is defined as an imaginary plane, the imaginary plane is arranged so as to be perpendicular to an axis of the roller and so as not to overlap the conductor part of the cable.
