本发明提供种旋转连接器，其具有能够提高转向角检测性能的同时实现小型化的转向角传感器单元。包括转子(21)、转向角传感器单元(12)、及可动侧壳体(50)，其中，该转子(21)在内筒部(21a)的外周面上体成形有沿着旋转方向的主齿轮(31)，该转向角传感器单元(12)具有：固定侧壳体(40)，转子(21)插通于该固定侧壳体(40)；行星齿轮(47、48)，其与主齿轮(31)啮合；及旋转角检测部(45)，其检测行星齿轮(47、48)的旋转，该可动侧壳体(50)具有与内筒部(21a)连结的外筒部(55)。 A rotating connector includes a movable housing and a steering angle sensor unit. The movable housing includes a cylindrical section through which a steering shaft penetrates and a main gear integrally molded with the movable housing on an outer circumferential surface of the cylindrical section along a rotation direction. The steering angle sensor unit includes a fixed-side housing into which the cylindrical section of the movable housing is inserted, a satellite gear which is provided in the fixed-side housing and meshed with the main gear, and a rotation angle detection unit which is provided in the fixed-side housing and detects rotation of the satellite gear.
