PROBLEM TO BE SOLVED: To provide a turntable capable of visually confirming a light emission part, regardless of the rotation angle of the rotating part. SOLUTION: The turntable 100 is equipped with a fixed part 103 and the rotation part 102, supported rotatably about a predetermined shaft on the fixed part 103. An LED 108 is provided to the fixed part 103, and the light emitted from the LED 108 passes through a light guide 105, provided to the rotation part 102 and radiated to the upper part of the rotation part 102. An optical path for guiding the light emitted from the LED 108 to the upper surface of the rotation part 102 is formed inside the light guide 105. The light, radiated from the upper surface of the rotation part 102 along the optical path, forms a light-emitting part 111. The position where the light emission part 111 is formed on the upper surface of the rotation part 102 is a position that corresponds to a rotation reference position (0(rad)), regardless of the rotation angle of the rotating part 102.
