真円度測定装置。 A magnetic displacement meter that rotates around the central axis of the inner circumferential surface is housed in a non-magnetic case with its operating direction aligned with the radial direction of the inner circumferential surface whose roundness is to be measured. The scale is positioned outside the surface, inserted from the outside to the inside of the inner peripheral surface, and is elastically supported by the case so as to be movable in the operating direction of the magnetic scale, and to operate the magnetic displacement meter as the scale moves. A roundness measuring device characterized in that a contact element that comes into contact with the inner circumferential surface is held at the tip of a non-magnetic movable body.
