Claims

[Claim for Utility Model Registration] A limit gauge head that can be inserted into a hole to be measured in a workpiece positioned on a surface plate, and a position axially distant from the limit gauge head for measuring the position of the hole to be measured. a first measurement position where the limit gauge head is inserted into the hole to be measured, and a second measurement position where the limit gauge head measures the hole position of the hole to be measured. a slide rod that can take a measurement position; the slide rod is guided and held between the first and second measurement positions, and when the slide rod is in the first measurement position, the limit gauge head is set to the measurement target; a floating bush movably held by the holding member on the surface plate so as to be movable only in a direction perpendicular to the axis within the limit tolerance of the hole position; and a floating bush that is moved to the second measurement position. A positioning member for positioning the slide rod or the floating bush at a reference position for hole position measurement when the slide rod or the floating bush is located at a reference position for hole position measurement.
