A rotation detecting device (1) includes a rotation operation part (5) configured to be rotationally operated, a first detector (10) configured to detect a rotation of the rotation operation part (5)and output a first rotation detection signal, a second detector (20) configured to output a second rotation detection signal, with a predetermined phase difference with respect to the first rotation detection signal, a third detector (30) configured to output a third rotation detection signal, with each of a predetermined phase difference with respect to the first rotation detection signal of thefirst detector and a phase difference with respect to the second rotation detection signal of the second detector, and a controller (40) configured to, based on the first rotation detection signal, the second rotation detection signal, and the third rotation detection signal, perform detection of a failure of the first detector (10), the second detector (20), or the third detector (30). 本发明提供能进行故障检知的旋转检测装置。具有：进行旋转操作的旋转操作部(
