In the above-described conventional configuration, when the laser displacement meter 2 is used, the state of reflection changes depending on the color and gloss of the inner surface of the tube. Although a coating film is formed on the inner surface of the tube, the coating film is not uniform in color and has different color spots and gloss depending on portions. This becomes noise and causes an error in the measured value.

In addition, it is necessary to maintain the positional relationship between the prism 3 and the laser displacement meter 2 strictly, and it is necessary to take care not to cause bending or the like of a member supporting the two.
If the member supporting the prism 3 is lengthened in order to measure a deep position in the tube, the shape becomes large to secure the strength of the member, and it becomes difficult to insert the member into a small-diameter tube. Since the laser spot applied to the inner surface of the tube is small, it is necessary to accurately apply it to the measurement location. However, the mechanical positioning accuracy of the prism 3 is coarser than the spot diameter, so that the spot is sometimes located at an incorrect location. there were.
When there was a groove-shaped concave portion on the inner surface of the tube, the bottom of the groove was rough due to the difficulty in processing, and it was not possible to obtain a reliable reflected light of the laser, and measurement was not possible. Further, the calibration work of the laser displacement meter 2 is troublesome, and it is difficult to perform the calibration work in a short time at the start of a day or in the cycle of the measurement work.
