するエレクタ装置。 An erector device comprising an erector ring rotatably supported in a shield tunneling machine and rotated in forward and reverse directions by a rotation drive motor, and an angle detector for detecting the rotation angle of the erector ring, wherein the erector ring is provided with an angle detector for detecting a rotation angle of the erector ring. An angle detection pinion that is meshed with a ring gear and driven to rotate, an angle detection hydraulic motor, and the angle detector are coaxially connected, and the generated torque drives the angle detection hydraulic motor. What is claimed is: 1. An erector device, characterized in that the erector device is connected to a hydraulic circuit such that the torque is smaller than that generated by a motor, and the angle detection pinion is always pressed in the same direction against the ring gear.
