摘要：
A rotating machine includes a rotating part rotatably supported by a bearing disposed between a first stationary part and a second stationary part. A rubbing position identification device determines, when rubbing occurs on the rotating machine, whether the occurrence position of the rubbing is a first unit including the first stationary part or a second unit including the second stationary part, based on an AE signal detected by a pair of first AE sensors attached to the first stationary part and the second stationary part, respectively.
