To provide an inside diameter measuring unit capable of automating the inside diameter measurement and a control method of automatic inside diameter measurement.SOLUTION: An inside diameter measuring part is supported by a support frame via a floating joint part. The floating joint part includes a rotation allowing mechanism allowing the inside diameter measuring part to rotate with respect to the support frame part, and a translation allowing mechanism allowing such displacement that the inside diameter measuring part translates with respect to the support frame part. A measurement head of the inside diameter measuring part is inserted into a hole by a robot arm part. The inside diameter measuring part autonomously adjusts a position and an attitude by reaction force when a probe presses an inner wall of the hole, and accordingly, the axis of the inside diameter measuring part matches the axis of the hole. The inside diameter of the hole can be automatically measured by an electric inside diameter measuring unit (an electric inside diameter measuring instrument and a robot arm part).SELECTED DRAWING: Figure 22 【課題】内径測定を自動化できる内径測定ユニットおよび自動内径測定の制御方法を提供する。【解決手段】内径測定部はフローティング継手部を介して支持フレームに支持されている。フローティング継手部は、内径測定部が支持フレーム部に対して回転することを許容する回転許容機構部と、内径測定部が支持フレーム部に対して並進する変位を許容する並進許容機構部と、を有する。ロボットアーム部によって内径測定部の測定ヘッド部が穴に挿入される。測定子が穴の内壁を押すときの反力によって内径測定部は自律的に位置および姿勢を調整し、内径測定部の軸線と穴の軸線とが一致する。電動内径測定ユニット（電動内径測定器、ロボットアーム部）によって穴の内径を自動的に測定することができる。【選択図】図２２
