測定装置である。As described above, the present invention allows the measuring tip of the dial gauge that is in contact with the inner end of the piston member to expand and contract depending on the position of the tip surface of the piston member and the position of the collar of the collet member that enters the inner circumferential groove. Since the dimensional difference is indicated on a dial gauge, the device is compact and can be easily operated with one hand, so even non-experts can easily and accurately measure dimensions, and the measurement time is greatly reduced. Therefore, it is a groove position measuring device for inner circumferential grooves that is most suitable for use in the field, especially in places where quick, easy, and accurate measurement is required, such as assembly sites.
