A surface texture measuring instrument has a rotary table on which a workpiece is rotatably mounted, a Z-axis slider capable of moving in a Z-axis direction parallel to a rotation axis of the rotary table, an X-axis slider that is held by the Z-axis slider and is advanceable and retractable in an X-axis direction orthogonal to the rotation axis, a first arm that is held by the X-axis slider and is rotatable around a center line parallel to the X-axis, a second arm that is held by the first arm and is advanceable and retractable in a direction orthogonal to the X-axis, and a detector held by the second arm to measure a surface texture of the workpiece.

A reference fixture () for a roundness measuring instrument performs acquisition of origin information of a roundness measuring instrument () including a workpiece rotary mechanism () on which a workpiece is set and a probe () provided with a stylus () and also performs calibration of the probe (). The reference fixture () includes a mount (), a calibration master () provided on a top face of the mount () for calibrating the sensitivity of the probe (), an origin ball () disposed above the calibration master () for providing the origin information of the roundness measuring instrument () by the stylus () of the probe (), and a holder () that holds the origin ball ().
