[과제] 회전 커넥터 장치에 있어서, 강도를 확보하면서, 스티어링 회전시의 슬라이딩 음을 저감한다. [해결 수단] 회전하는 로터(5)와 고정된 스테이터와의 사이의 환상 공간내에, 플랫 케이블(3)이 감겨져 수납된 회전 커넥터 장치에 있어서, 로터(5)는, PBT 수지제의 로터 본체(6)와, 환상 공간에 면하는 폴리아세탈계 수지제의 로터 커버부(15)를 겹쳐서, 강도를 확보하면서, 플랫 케이블(3)과 로터(5)의 슬라이딩 음을 저감한다. 플랫 케이블(3)을 로터 본체(6)로부터 환상 공간으로 인출하기 위해서 로터 커버부(15)에 개구부(72)가 형성되고, 로터 본체(6)와, 로터 커버부(15)의 조립시의 작업 효율 향상을 위해서 원반부(16)에 오목부(70)가 형성된다.

    There is provided a rotary connector device in which a flat cable (3) is wound and accommodated in an annular space (S) between a rotating rotor (5) and a fixed stator (30). The rotor (5) is provided with a rotor main body made (6) of a PBT resin, and a rotor cover portion (15) made of a polyacetal resin and overlapping the rotor main body (6) to ensure strength of the rotary connector device and reduce sliding noises between the flat cable (3) and the rotor (5). The rotor cover portion (15) is provided with an opening portion (72b) for pulling the flat cable (3) in the annular space (S) out of the rotor main body (6), and a concave portion (70) is formed in a disc portion (16) of the rotor cover portion (15) for improving work efficiency at the time of assembling the rotor main body (6) and the rotor cover portion (15).
