Beschreibung
Zusammenfassung:	This displacement detecting sensor is provided with two encoders attached to a first link and a second link that are coupled in such a way as to be capable of moving relative to a certain axis, wherein: the two encoders are provided with two scale members at different distances from the axis, and two detectors for detecting scales on the respective two scale members; a positional relationship between the scale members and the detectors changes in accordance with an external force accepted at the distal end of the second link, generating a difference between the two scales detected by the two encoders; and the displacement of the distal end of the second link can be detected on the basis of the two scales.
