PROBLEM TO BE SOLVED: To prevent erroneous counts caused by vibration of a vibration machine generated by large amplitude vibrations in directions other than the measurement direction, such as a press machine. SOLUTION: The displacement measurement device of the vibration machine 40, vibrating in directions other than the measurement direction, comprises a scale 50 fixed to one 48 of relative displacement members and a direct drive guide (rail 52), a detector 56 fixed to a slider 54 of the direct drive guide, and a link 60 rotatably connected between the slider 56 and the other 46 of the relative displacement members.
