<p>PROBLEM TO BE SOLVED: To provide an auxiliary measuring tool capable of preventing the work efficiency from being decreased in measuring work of the distance of the center interval of a screw structure.SOLUTION: An auxiliary measuring tool includes: a base member installed on a screw structure; and a fixing member 3 on a shaft fixable with the end part of a scale. The base member includes: a socket part 20 having a fitting recess 200 fit to a polygonal shape part of the screw structure; and a female thread part 21 having a screwing recess part 210 screwed to the female thread part. The fixing member 3 is configured to provide the socket part 20 and the female thread part 21 in such a manner that the fitting recess part 200 and the screwing recess part 210 are opened in a direction reverse to each other. The fixing member 3 is insertably inserted to the socket part 20 and the female thread 21 so as to extend over the fitting recess part 200 and the screwing recess part 210, and respective end parts in an axial direction can fix the end parts of the scale.</p> |
