Abstract
In a surface texture measuring instrument, a measurement arm includes: a first measurement arm that is supported by a bracket around a support shaft movably in a circular movement in a casing; and a second measurement arm having styluses that are attachably and detachably provided to an end of the first measurement arm via an attachment-detachment mechanism, the attachment-detachment mechanism being arranged in the casing. A displacement detector includes: a scale provided to the measurement arm; and a detection head provided to the bracket to face the scale. A detecting surface of the scale is on an axis of the measurement arm and on a plane of the circular movement of the measurement arm.
