Zusammenfassung:A displacement measuring device for a vibration machine (40) vibrating in a direction other than a measuring direction includes: a scale (50) and a linear motion guide (rail 52) which are fixed to one relative displacement member (48), and a detector (56) which is fixed to a slider (54) of the linear motion guide, and a link (60) which freely rotatably couples the slider (54) and the other relative displacement member (46) . This prevents occurrence of erroneous counting due to vibration in a vibration machine.
