Zusammenfassung:	PURPOSE:To enable to apply the titled detector to a rotary part of an industrial robot by making the titled detector possess both a bearing function of a rotary shaft and a rotary position detecting function, by providing a rotary displacement detector on a rotary bearing unitarily, in the rotary bearing provided with an inner and outer rings. CONSTITUTION:A rotary bearing, for example, a ball bearing is provided with an outer and inner rings 1, 7. In this case, the outer ring 1 is provided with a magnetism detecting head 9, the inner ring 7 is provided with a coded ring 6 to which a code based on the magnetism is recorded and a groove part of the outer ring 1 is provided with a stress detecting mechanism based on a strain gauge 12. With this construction, the titled bearing can detect highly accurately a rotary position, bending stress and thrust stress while it is functioning as the rotary bearing of a joint part and a rotary part of a robot especially.
