PROBLEM TO BE SOLVED: To provide a diagnostic device of a rolling bearing unit capable of highly accurate detection without overlooking a defect of a rotating part of a mechanical device, when performing an inspection test periodically, while rotating the device, without decomposing the mechanical device requiring much labor for decomposition. SOLUTION: This diagnostic device 10 of the rolling bearing unit is a device for diagnosing abnormality in rolling bearings 11, 11 on which a radial load is loaded, and has a thrust force imparting mechanism 18 for imparting an optionally-varied thrust force to the rolling bearings 11, 11 installed on a rotary test stand, and performs a rotation test, while loading the thrust force on the rolling bearings 11, 11 by the thrust force imparting mechanism 18.
