description An elevator troubleshooting apparatus of the present invention is characterized by comprising detection means (1, 2) for detecting an amplitude value of any one of vibration acceleration and noise related to any one of various kinds of devices of an elevator, wavelet conversion means (8) for conducting wavelet conversion for a detection output of the detection means and thereby generating wavelet spectrum data, and troubleshooting means (9) for diagnosing occurrence of an abnormal condition at the elevator in accordance with magnitude of an amplitude value represented by the wavelet spectrum data generated by the wavelet conversion means.
